Thanks for the review and kind words. We'll see about other color options. When this pack was developed last year Ultra 200 only came in white (cool but gets dirty) and black (gets really hot and melts the chocolate), so we worked with Challenge to develop this grey and then opened up the color to other gear makers. At the time I looked at other colors too but there were only a few options and they were all pretty bad. I'll keep looking at it. Colors are a tough one though - the original green of the DD40 wasn't that well received.
@@teufeldritch The sage green in the tents was a huge hit. The green in the DD40 was a bit different and was received fine, but some people didn't like it in combo with the grey.
I love this channel so much, just straightforward insightful info that explains actual design concepts behind the packs, not just a shallow “this” vs “that” brand/model!
This is very similar to the solution Outdoor Vitals came up with for their Shadowlight pack. Under 2 pounds but with a frame that has some horizontal rigidity. I have to admit it became my favorite pack very quickly. Now I am super curious about this Durston pack; I'm usually extremely pleased with the quality of Durston gear, so now I have to try it!
@@user-pe6mv1kd5p the Hyperlite pack shown in this video is $370, the Durston pack is $250 and the Osprey Atmos is $300. The levity is $149 right now on their website so yeah do some research. Also light equipment isn’t cheap, we’re talking competitive and comparable gear.
Glad to hear you like the pack! I was hoping this hit the mark of that in between space of being ultralight but still supportive. My Atmos 65 is definitely heavier than it needs to be and I found I didn't use half the pockets during our last trip so i'm trying to optimize my weight. Super excited for Kakwa 55L option they are working on for next year. Hoping to crack under 30lbs with bear can and 3L water!
Just used my Kakwa 40 on my 10day hike TMB in Sept and found it very comfortable. Also, I was concerned about losing my gear in transit from Australia to Geneva, Managed to pack all my essential gear into the pack and keep the size and weight to on airline carry-on 7kg limit.
Its weighs 3,17 lbs for the regular, thats more than a little more than 1,75 lbs and while i dont know the price of the durston i didnt find the granite cheap. I am currently eyeing the exped lightning 60, its cheaper and only wheighs 2,69 lbs. I would think its a better option, the padding looks good too.
@@jonathankobbe6073 I only got into backpacking last year with an OLD North face 80L. I think that beast weighs almost 8 pounds. Hearing you guys taking about 3.17 is too much in going for 2.6 just make me laugh 🤣🤣🙃 But really my main "what am I missing?" Is around size. I have a down sleeping bag that is a tight fit in my 80L bag. And I don't think I've been able to fit it under the trampoline. How in the world could anyone take a bear canister and a sleeping bag in a 40L pack just amazes me. LOL I'll learn as I go though
40 liter too small for me, but I am intrigued about any ultra light stuff that has any kind of abrasion resistance and is generally somewhat abusable. The price isn’t insane given today’s prices for nearly anything. But I’ll stick with my 95 liter Gregory, the one with the zippers and pockets and straps and stuffs. It would make an ultralighter’s head explode, which would kind of be fun to watch if I’m being honest! 😂
The problem with both of the Durston packs lies in the shoulder straps. They work ok for some, but the yoke of material between the straps doesn’t allow the straps to form to shoulders like independent straps. They’re a bit thinly padded too. Dan is really innovative, but I think spent soooo much time focused on the things other packs miss, he missed the things others get right.
Off topic for this video but had my feathered friends flicker quilt 20° down to 24° the other night. Did great! Slept in 250g merino wool base layers and was warm.
I feel you should take a look at Sierra Designs Flex Capacitor. It weights a little bit mora than shown on video, but has far less compromises and suitable for far larger audience than the one presented.
As soon as I saw the internal frame of this pack I just thought it was a less well designed version of the flex capacitor Y frame. I think people see the "flex gimmick" of the flex capacitor and write it off but the best feature is the Y frame. Although I still love all the straps and ability to cinch it down.
@@cullumash I don't care a lot about it's ability to change volume to be honest. But I like it's "normal" feel with minimal weight, comparing to other ultralight options. Choosing 40-60 version also gives you a lot of space, which most people will use.
This right here, the flex is the most under rated and under talked about bag IMO. Its never seen or suggested, but everyone who tries one LOVES it. (as did I). Its super comfortable, cheap and works amazingly well. plus everyone complains about carrying bear canisters, either they dont fit or are strapped on awkwardly.... guess which bag does that just fine?
I was torn between this and the Gossamer Gear Mariposa. I love Durston Gear, but the size ended up being a deciding factor. So anyone looking into this but are worried about the size, the Mariposa has similar features and weight, with the extra room.
I think I read that the Mariposa (which I was considering) is 60L with all of the pockets etc. included while Dan's pack is 40L for just the main compartment (slightly larger than the Mariposa if I remember correctly). Anyway, I have a Kakwa 55 on order and think it will suit my needs. I do think that GG make a lot of nice gear though.
Totally agreed. IMO, the intermediate between standard and ultralight packs is the sweet spot. Something with a true frame that provides support but without the heavy bag materials and unnecessary pockets and zippers that most traditional packs have. Something that is in the 2-3lb range but has enough structure to carry a full load of gear comfortably is perfect. This Durston pack looks awesome, I hadn't heart much about it before this video.
Hip belt size options was the main reason I wasn't able to go with this pack. Hopefully in the future that may change cause I still think about the Kakwa almost everyday.
My new favorite pack is made by Nashville Packs. It is an ultralight frameless pack that is more comfortable than any pack of any kind I’ve owned previously.
Great review. I always need a 70+ litre back pack with multiple pockets as I’m looking after young boys on multiple day hikes. I’ll stick with my Osprey Aether plus 70L for now. Maybe in 5 years time I’ll look at getting one of these. Glory to all Outdoors creatures!
I dunno...if you regard a pack not being "ultralight" but offering you lots of possibilities to fix gear you might want to access without unpacking half of your stuff - like your drinking bottle, money, small snacks, first aid kit, camera, trekking poles etc. - as a "big problem", then yes, that's what "traditional" packs are meant for. But I wouldn't speak of a big problem there, it's a different set of features and very handy for most beginners to have your stuff a bit more organized. This just becomes a big problem when gram counting gets more important then comfort to you personally.
I just used the kakwa for an overnight section hike in Pennsylvania, pack worked great, but.......seems like it would be better for summer pack for me, it was 34 degrees at night and the pack just seemed really high and full with temp appropriate gear. Gonna use my waymark 50l for a trip next wk
Z packs are flat also, good idea, I have a 3400 Southwest and just picked up a Gossamer Gear Kumo for the kid. That back pocket needs to be bigger. The 3400 can feel overloaded, but WOW that extra space for a food carry and a full size pillow is something that I need. I carry the food for the family to keep their packs well under 15lbs. Im at 31lbs and under 20 on the way down cool vid thx
Kluttermusen uses same system of aluminum tubing for frame. It does make a pack much more comfortable yet keeping it light at the same time. One negative about it is much easier to break aluminum tube and then it's a huge pita to make a new one. Apparently it is quite a skill to bend alumnium tubing without intoducing weak spots. But with regular stays any home depot sell them 3.50 a foot no biggie.
I got the first Dan Durston pack and the HMG southwest 2400. I agree with the benefits of the reversed U frame however the DD40 was giving trouble with the gears rounding up the pack unlike the southwest. I guess it was improved with Kakwa. On a side note, Dan already mentioned a 55L version of this could be released. I’ll probably get one if it happens.
Osprey exos 58 is just a bit over 2#...and have all the comfort I want. I want this 40l pack but my Osprey is so good. Hard to spend the cash for a few oz.
The Outdoor Vitals Shadowlight series has a very similar suspension system. I own both the Shadowlight and the Kakwa pack and the Kakwa is my favorite. The fit and function is amazing!
Kakwa 40 doesn't have proper seam allowance for the Ultra 200 which is being corrected in the next iteration. Also, the foam padding is a little thin and light IMO.
What do you mean by "seam allowance"? I have heard that the Ultra 400 used in Pa'Lante packs shows some seam stretching due to fabric stretch and stitching choices made by the company. I haven't seen a video that shows this issue after significant use (PCT Thru-hike) so am curious if that is your concern with this pack and the Ultra 200 fabric. I own the Pa'Lante Desert Pack that is made using the Ultra 400 but have not put it through as rigorous a test as a thru-hike. The Pa'Lante is seam taped.
Ultra fabric is approximately 2/3rd's UHMWPE yarns woven with approx. 1/3rd polyester yarns, and then a PET film is laminated to one side for waterproofing and dimensional stability of the yarns (UHMWPE fibers and yarns are very slippery). It is a *very* different material than DCF. The strength, abrasion resistance, etc. will vary depending on what weight and type of DCF you're comparing it to. But it will be much stronger and more abrasion resistant than almost all DCF materials. You may not like the dark grey color, but the darker colored a synthetic material, the better and longer it will last in relation to UV exposure. Organic synthetics like nylon, polyester, and to a lesser extent UHMWPE get broken down and weakened by UV faster than people realize (especially when in the form of relatively thin fabrics). With that said, UHWMPE material handles UV better than nylon, polyester, and PU. The colorant acts as a UV absorber, somewhat like the melanin in our skin, and just like with melanin and our skin, the darker the color, the more UV it absorbs. But if you had a white pack, even with it being 2/3rds UHMWPE, you'd see significant decrease in the various strengths and durability of the fabric within a few years if you're out a lot in the sun with it, especially in the higher elevations during summer and south to mid latitude. Personally speaking, I'm looking for ultra durability over ascetics. (One way to decrease this process is to use a decent sized reflective umbrella). I'm so anal about durability, that I may attach a sacrificial flap/covering of very light weight, black silpoly over the top and back, and over the straps.
So far I really like the Kakwa but I agree with your criticism of the front mesh. I wish it was the stretchy lycra and had more capacity. Also, the tall side pocket is a bit too snug. Wish it was bigger.
Stretch lycra mesh works pretty awesome but we avoid it because it is much easier to damage. It's perhaps the single most common failure point on packs, which is seemingly why Zpacks recently stopped using it. We use a non-stretch mesh with pleats to add volume that is a bit smaller but will last a lot longer. I do agree that it would be nice to boost the volume more. Our upcoming 55L version has more space in the front pocket.
@@durstongear Thanks for reply. Always appreciated. Good to hear a larger volume pack coming. Hope tall side pocket has bigger opening and draw string closure. My 40 has very small opening and elastic is way too tight. Ive never had any issues with the lycra. Still my personal preference.
Great review. I wish they would make the packs with a larger diameter. I don't like going high in the tub of my pack. I've been using a home built Ray Way pack for about 11 years now. Great pack but I need more room down low. If you use the top it wants to fall away.
At least for me, the load lifters completely eliminate that “falling away” feeling when the pack’s is loaded to its full height. But the 55L coming in a few months would certainly have a larger diameter and would presumably still be a rolltop so you wouldn’t have to use the full height.
I did a quick search on your channel and nothing came up, but it'd be nice to know what somebody like you with all this gear does with stuff when you're done testing it. Is most sent back to the vendor? Do you just sell it? I like behind the scenes stuff of how various RUclipsrs run their channels. Amazing how many things aren't obvious until it's shown/explained to us!
The most comfortable pack I've ever owned. I had a 750ml bottle in the ez grab pocket and a 1L in the taller pocket and was able to run and bounce down the trail with no jiggling around.
I see there is now a Kakwa 55 but both the Kakwa 40 and the Kakwa 55 are sold out as of Aug 6, 2023. I'd be ok with the grey or white. Still not sure if I'm going to buy an ultralight pack since I like the traditional packs but maybe I'll give it a try someday.
I got this as soon as it came out and is the best! I can’t wait for a full season with it but it serves me great late summer though fall. It’s the best thought out pack and I’m in love with it
Quick little tip for your supercool gear channel: the G for grams behind the weights you (thankfully!) provide in your videos should be small. At least for Europe it's common to write e.g. 354g, not 354G. Same goes for 10kg, if it's 10 kilograms. If it's a formatting issue with your typeface, just forget I wrote this ;-)
You need to do a review of the Outdoor Vitals Shadowlight 60. This pack looks like it largely takes design elements from the OV pack, and the center zipper on the Shadowlight makes it absolutely super versatile. I’ve had one since they came out and almost never use anything else.
Z-packs arc series has a terrific frame and suspension package for the weight, and I’ve never had it “round out”. Sits equally on my shoulders and hips and not anywhere else. And they’ll send you one tomorrow
I agree completely with this comment. I have an Arc Ultra 60 that weighs less than the Kakwa, has a breathable mesh back that works as advertised, and the pack can easily handle a bear canister. Assorted colors would be nice, but absolutely last on my list of desirables.
The old Alumuinum frame external packs were the best design if you got the right pack to use on the frame and were light too if you got the right combo. It is too bad now they are only made in hunting designs with extra framing people do not need for backpacking and often have to modify these packs to have them work with a backpack if you never plan to use it hunting. The other flaw with some fastpacks is they are designed for running packing and not really enough to the pack to do overnight packing, mainly made for running nonstop some longer routes over 38--40 miles depending on needs and size of pack at 20--25 liters up to 30 Liters when 39--40 liters on up is what you want in ultralight camping packs as 30--35 liters is really only good for overnight with a tube tent/tube tarp if you go Dinner of the night before and Breakfast as the only meals and basically sleeping the night. The 30--35 Liters category is where the old overnight rust-sack/stupidly named large/extra large nap sack fit in.
Would be interesting to see your thoughts on ULA packs, they share a lot of the things you enjoyed about the Kakwa and have a full line of pack sizes. They’re admittedly a bit heavier, their most comparable pack is probably the Circuit Ultra at 35 OZ, but it also has more external storage and additional hip belt load lifter doodads (load stabilizers?) They also make Robic Nylon packs that are marginally heavier but around $100 cheaper.
Looks like a really nice pack. 👍 Volume keeps my favorite pack (Granite Gear Crown 2) in the running for best pack that doesn't get near enough love. The side pocket design is my number one wish for the Crown 2.
You all need to try the English made Atom Packs Atom plus and the Mo. They both have frames which as you say have horizontal and vertical support. They easily challenge the weight of this and the Mo has load lifters and can carry 18kgs. They also have a better choice of customisations and capacities. Above and beyond what I've seen on offer elsewhere. Prove me wrong.
True, this pack is only 40L which might be small for winter gear plus a bear canister. However, it should have been mentioned that a 55L will also be available and that should be plenty adequate.
Do you have a ballpark $ range on this pack? Since it's ultra I'm assuming near the $400 which, for a framed pack at that weight is pretty pricy. While I think you make some interesting points in this one Steven I personally never saw an issue with bowing on a framed pack. With a slimmer frame profile or a frameless pack you need to be more aware of how you pack your bag or go with a full panel that weighs more. I don't see how this pack will take off based on the weight to price ratio. It's a lot like Waymark packs in that regard. When there are lighter or cheaper options it's hard to justify packs like these. Great video!
I have a 60l pack made by Vango with the U shape aluminium support from over 20 years ago, I think it might even date from the late 80s early 90's as it was my step-fathers hand me down to me. It's nothing new!
I haven’t tried yet. I’m going to use the BV450 which is a smaller canister. I’m worried it will slide out from under the strap. I’ve also read the strap isn’t quite long enough for a bear canister
Pants Open weave material (as a solution) (not too hot, not too cold) Kathmandu colors (outdoors style since 1980's) the typical Nepalese colors. Japanese colors and prints as an alternative. Natural colors and many others... (if manufacturers want to stand out style wise)
Well before the ultralight kick the original internal frame packs were almost all two parallel aluminum stays, usually 6061t. 7000 series aluminum is much stiffer.
i will stick with my alice pack lg thank you. i was never fond of internal frame packs. they always did what you talk about here and just rubbed me raw.
I know I may be the odd man out here but I couldn't find anything that fit my ideal version of a pack in any of the traditional backpacking packs. Just recently I found a pack by stone glacier called the terminus. It gets me 115L of space for less than 4 pounds and there isn't a single pack in the backpacking world that matches the comfort that this pack offers. I would be really interested in seeing more backpackers review these hunting packs.
Hey man, quick question-- if you were worried about the bulky items such as your clothes and bear canister, how come you went with the 40L? I hike and backpack in the Adirondacks a lot, and I am looking at the Kakwa 55L. I am also looking at the X-MID 2 from Durston. I currently have an Osprey Exos 58L and it's nice, but I'd like something a little lighter. I'm a seasoned hiker but new to backpacking as I've only gone on 2 overnights starting this year (I'm hooked!). Not an ultra-lighter, but looking into Durston for lightening up my kit. Love your videos!
Just started backpacking and used the Hyperlite 3400 and it was great, I loved how light it was. I am looking to buy a pack, I borrowed the last one, is the Ultra200 better than the material on the 3400, do you think it's waterproof to do you need a cover for this? I am new to this and not sure about companies, is this a reputable company I can trust to take on a good hike and not worry about it falling apart? Sorry so green to this, seem like the 3400 has been around so it seems like its built really nice and lots of great resources and reviews, this seems newer and fixes some issue like you said...Any other advise, thanks so much!
You described two problems of the backpack. There are eight more problems. Outdoor sport backpacks sold throughout the world have five to eight bio-mechanical inefficiencies reducing a persons’ speed, endurance, comfort and generates fatigue. The spine is the center of human torso rotation that provides efficient human forward motion. The backpack is placed on the torso which rotates about twice that of the hips. Loads placed at the spine reduces waste motion which reduces waste energy. Loads placed at a distance from the spine generates thrusted motion generating waste energy required to return the thrusted load. 1. Backpacks extend to a person’s hips or lower eliminating one's inherent pace speed. 2. The width of backpacks causes gear storage side to side thrusting generating waste energy. 3. The depth of backpacks causes gear storage side to side thrusting generating waste energy. 4. Water is normally the heaviest load carried in or on a backpack. Placed at the side pockets it causes thrusting generating waste energy. 5. Hip belts reduce breathing by about 25 percent valuable for speed and comfort, not necessary for loads less than 20 pounds except to reduce side to side thrusting. 6. Water stored on shoulder straps generates side to side thrusting generating waste energy. 7. Shoulder straps not placed on the trapezius muscles pull the backpack forward and up with each step generating waste energy. 8. During the summer season, lack of air space on the back generates perspiration and elevated heat generating fatigue. The backpack lacks frontal storage for quick access to emergency and preferential gear thus necessitating the removal of the backpack for access to gear wastes time. A balanced load, front and rear reduces shoulder stress and transfers a persons’ center of gravity forward for reduced energy expenditure carrying a load.

Great review. I always need a 70+ litre back pack with multiple pockets as I’m looking after young boys on multiple day hikes. I’ll stick with my Osprey Aether plus 70L for now. Maybe in 5 years time I’ll look at getting one of these. Glory to all Outdoors creatures!
I dunno...if you regard a pack not being "ultralight" but offering you lots of possibilities to fix gear you might want to access without unpacking half of your stuff - like your drinking bottle, money, small snacks, first aid kit, camera, trekking poles etc. - as a "big problem", then yes, that's what "traditional" packs are meant for. But I wouldn't speak of a big problem there, it's a different set of features and very handy for most beginners to have your stuff a bit more organized. This just becomes a big problem when gram counting gets more important then comfort to you personally.
I just used the kakwa for an overnight section hike in Pennsylvania, pack worked great, but.......seems like it would be better for summer pack for me, it was 34 degrees at night and the pack just seemed really high and full with temp appropriate gear. Gonna use my waymark 50l for a trip next wk
Z packs are flat also, good idea, I have a 3400 Southwest and just picked up a Gossamer Gear Kumo for the kid. That back pocket needs to be bigger. The 3400 can feel overloaded, but WOW that extra space for a food carry and a full size pillow is something that I need. I carry the food for the family to keep their packs well under 15lbs. Im at 31lbs and under 20 on the way down cool vid thx
Whoa. The price on that's very reasonable. With those features, color me intrigued on my list next time I'm pack shopping!
Am loving my Kakwa!
That frame for the Kakwa is identical to the Outdoor Vitals Shadowlight. And it is amazing!! With load lifters, comes in at the similar weight.
Kluttermusen uses same system of aluminum tubing for frame. It does make a pack much more comfortable yet keeping it light at the same time. One negative about it is much easier to break aluminum tube and then it's a huge pita to make a new one. Apparently it is quite a skill to bend alumnium tubing without intoducing weak spots. But with regular stays any home depot sell them 3.50 a foot no biggie.
Black and gray looks sharp.
I got the first Dan Durston pack and the HMG southwest 2400. I agree with the benefits of the reversed U frame however the DD40 was giving trouble with the gears rounding up the pack unlike the southwest. I guess it was improved with Kakwa. On a side note, Dan already mentioned a 55L version of this could be released. I’ll probably get one if it happens.
Great post my friend. I appreciate all the information you are sharing here. 🏃♂️
Osprey exos 58 is just a bit over 2#...and have all the comfort I want. I want this 40l pack but my Osprey is so good. Hard to spend the cash for a few oz.
Interesting backpack! Thanks for sharing!
The Outdoor Vitals Shadowlight series has a very similar suspension system. I own both the Shadowlight and the Kakwa pack and the Kakwa is my favorite. The fit and function is amazing!
Kakwa 40 doesn't have proper seam allowance for the Ultra 200 which is being corrected in the next iteration. Also, the foam padding is a little thin and light IMO.
What do you mean by "seam allowance"? I have heard that the Ultra 400 used in Pa'Lante packs shows some seam stretching due to fabric stretch and stitching choices made by the company. I haven't seen a video that shows this issue after significant use (PCT Thru-hike) so am curious if that is your concern with this pack and the Ultra 200 fabric. I own the Pa'Lante Desert Pack that is made using the Ultra 400 but have not put it through as rigorous a test as a thru-hike. The Pa'Lante is seam taped.
Ultra fabric is approximately 2/3rd's UHMWPE yarns woven with approx. 1/3rd polyester yarns, and then a PET film is laminated to one side for waterproofing and dimensional stability of the yarns (UHMWPE fibers and yarns are very slippery). It is a *very* different material than DCF. The strength, abrasion resistance, etc. will vary depending on what weight and type of DCF you're comparing it to. But it will be much stronger and more abrasion resistant than almost all DCF materials.
You may not like the dark grey color, but the darker colored a synthetic material, the better and longer it will last in relation to UV exposure. Organic synthetics like nylon, polyester, and to a lesser extent UHMWPE get broken down and weakened by UV faster than people realize (especially when in the form of relatively thin fabrics). With that said, UHWMPE material handles UV better than nylon, polyester, and PU. The colorant acts as a UV absorber, somewhat like the melanin in our skin, and just like with melanin and our skin, the darker the color, the more UV it absorbs.
But if you had a white pack, even with it being 2/3rds UHMWPE, you'd see significant decrease in the various strengths and durability of the fabric within a few years if you're out a lot in the sun with it, especially in the higher elevations during summer and south to mid latitude. Personally speaking, I'm looking for ultra durability over ascetics. (One way to decrease this process is to use a decent sized reflective umbrella).
I'm so anal about durability, that I may attach a sacrificial flap/covering of very light weight, black silpoly over the top and back, and over the straps.
Love my Kakwa
So far I really like the Kakwa but I agree with your criticism of the front mesh. I wish it was the stretchy lycra and had more capacity. Also, the tall side pocket is a bit too snug. Wish it was bigger.
Stretch lycra mesh works pretty awesome but we avoid it because it is much easier to damage. It's perhaps the single most common failure point on packs, which is seemingly why Zpacks recently stopped using it. We use a non-stretch mesh with pleats to add volume that is a bit smaller but will last a lot longer. I do agree that it would be nice to boost the volume more. Our upcoming 55L version has more space in the front pocket.
@@durstongear Thanks for reply. Always appreciated. Good to hear a larger volume pack coming. Hope tall side pocket has bigger opening and draw string closure. My 40 has very small opening and elastic is way too tight.
Ive never had any issues with the lycra. Still my personal preference.
Great review...always practical. Love the little note at the very end too. :)
I got it when it dropped. I like it a lot.
Great review. I wish they would make the packs with a larger diameter. I don't like going high in the tub of my pack. I've been using a home built Ray Way pack for about 11 years now. Great pack but I need more room down low. If you use the top it wants to fall away.
At least for me, the load lifters completely eliminate that “falling away” feeling when the pack’s is loaded to its full height. But the 55L coming in a few months would certainly have a larger diameter and would presumably still be a rolltop so you wouldn’t have to use the full height.
I did a quick search on your channel and nothing came up, but it'd be nice to know what somebody like you with all this gear does with stuff when you're done testing it. Is most sent back to the vendor? Do you just sell it? I like behind the scenes stuff of how various RUclipsrs run their channels. Amazing how many things aren't obvious until it's shown/explained to us!
Gossamer gear uses the same design. Love mine!
Rumor has it that Dan in releasing a 55l version this winter
The most comfortable pack I've ever owned. I had a 750ml bottle in the ez grab pocket and a 1L in the taller pocket and was able to run and bounce down the trail with no jiggling around.
Durston gear kicks all the ass. Waiting on the Kakwa 55 to restock! Great video as usual 🍻
I see there is now a Kakwa 55 but both the Kakwa 40 and the Kakwa 55 are sold out as of Aug 6, 2023. I'd be ok with the grey or white. Still not sure if I'm going to buy an ultralight pack since I like the traditional packs but maybe I'll give it a try someday.
If I recall correctly, Sierra Designs uses a similar inverted "U" frame in its packs.
I got this as soon as it came out and is the best! I can’t wait for a full season with it but it serves me great late summer though fall. It’s the best thought out pack and I’m in love with it
Love the Kakwa, but HATE the SMALL stash pocket. I do not know what they were thinking to make it that small.
You try Eddie Bauer backpacks. They have a removable frame. They're aimed more at rock climbers and mountaineers.
Waiting on the Kakwa 55, hopefully in Feb! Will address the volume issue for bear canisters, which i always use.
Quick little tip for your supercool gear channel: the G for grams behind the weights you (thankfully!) provide in your videos should be small. At least for Europe it's common to write e.g. 354g, not 354G. Same goes for 10kg, if it's 10 kilograms. If it's a formatting issue with your typeface, just forget I wrote this ;-)
You need to do a review of the Outdoor Vitals Shadowlight 60. This pack looks like it largely takes design elements from the OV pack, and the center zipper on the Shadowlight makes it absolutely super versatile. I’ve had one since they came out and almost never use anything else.
Great review. The six moon design packs have a similar design.
Z-packs arc series has a terrific frame and suspension package for the weight, and I’ve never had it “round out”. Sits equally on my shoulders and hips and not anywhere else. And they’ll send you one tomorrow
I agree completely with this comment. I have an Arc Ultra 60 that weighs less than the Kakwa, has a breathable mesh back that works as advertised, and the pack can easily handle a bear canister. Assorted colors would be nice, but absolutely last on my list of desirables.
The old Alumuinum frame external packs were the best design if you got the right pack to use on the frame and were light too if you got the right combo. It is too bad now they are only made in hunting designs with extra framing people do not need for backpacking and often have to modify these packs to have them work with a backpack if you never plan to use it hunting.
The other flaw with some fastpacks is they are designed for running packing and not really enough to the pack to do overnight packing, mainly made for running nonstop some longer routes over 38--40 miles depending on needs and size of pack at 20--25 liters up to 30 Liters when 39--40 liters on up is what you want in ultralight camping packs as 30--35 liters is really only good for overnight with a tube tent/tube tarp if you go Dinner of the night before and Breakfast as the only meals and basically sleeping the night. The 30--35 Liters category is where the old overnight rust-sack/stupidly named large/extra large nap sack fit in.
Would be interesting to see your thoughts on ULA packs, they share a lot of the things you enjoyed about the Kakwa and have a full line of pack sizes. They’re admittedly a bit heavier, their most comparable pack is probably the Circuit Ultra at 35 OZ, but it also has more external storage and additional hip belt load lifter doodads (load stabilizers?)
They also make Robic Nylon packs that are marginally heavier but around $100 cheaper.
Looks like a really nice pack. 👍
Volume keeps my favorite pack (Granite Gear Crown 2) in the running for best pack that doesn't get near enough love. The side pocket design is my number one wish for the Crown 2.
I was waiting for your take on this pack...thanks
You all need to try the English made Atom Packs Atom plus and the Mo. They both have frames which as you say have horizontal and vertical support. They easily challenge the weight of this and the Mo has load lifters and can carry 18kgs. They also have a better choice of customisations and capacities. Above and beyond what I've seen on offer elsewhere. Prove me wrong.
Wow. This is pretty nice. Thanks for the review!
good presentation......
Great, informative breakdown. This vid earned you a new subscriber.
True, this pack is only 40L which might be small for winter gear plus a bear canister. However, it should have been mentioned that a 55L will also be available and that should be plenty adequate.
I hope you get to test the Kakwa 55.
Great review. However, I actually prefer my old Kelty Coyote 65. I LOVE the external pockets. Helps keep my gear organized.
Do you have a ballpark $ range on this pack? Since it's ultra I'm assuming near the $400 which, for a framed pack at that weight is pretty pricy. While I think you make some interesting points in this one Steven I personally never saw an issue with bowing on a framed pack. With a slimmer frame profile or a frameless pack you need to be more aware of how you pack your bag or go with a full panel that weighs more. I don't see how this pack will take off based on the weight to price ratio. It's a lot like Waymark packs in that regard. When there are lighter or cheaper options it's hard to justify packs like these. Great video!
I believe the price is $250
I have a 60l pack made by Vango with the U shape aluminium support from over 20 years ago, I think it might even date from the late 80s early 90's as it was my step-fathers hand me down to me. It's nothing new!
You can't use the Y strap to secure the bear canister?
I haven’t tried yet. I’m going to use the BV450 which is a smaller canister. I’m worried it will slide out from under the strap. I’ve also read the strap isn’t quite long enough for a bear canister
The REI Flash 55 is also a great hybrid pack that is very light
Where did you find convertible pants with vertical zips for your boots?
All I can find are the silly kind that require removing boots.
One reason I like my granite gear back, nice solid back frame that works for my body
Pants
Open weave material (as a solution) (not too hot, not too cold)
Kathmandu colors (outdoors style since 1980's) the typical Nepalese colors.
Japanese colors and prints as an alternative.
Natural colors
and many others... (if manufacturers want to stand out style wise)
Great video! Love the content, keep it up!
Checkout Atom Packs from the UK.
Very curious about this. Have an Arc air which carries fine and a Gregory which is more mainstream but comfortable
Well before the ultralight kick the original internal frame packs were almost all two parallel aluminum stays, usually 6061t. 7000 series aluminum is much stiffer.
i will stick with my alice pack lg thank you. i was never fond of internal frame packs. they always did what you talk about here and just rubbed me raw.
I know I may be the odd man out here but I couldn't find anything that fit my ideal version of a pack in any of the traditional backpacking packs. Just recently I found a pack by stone glacier called the terminus. It gets me 115L of space for less than 4 pounds and there isn't a single pack in the backpacking world that matches the comfort that this pack offers. I would be really interested in seeing more backpackers review these hunting packs.
Durston is like the brand of myth, never any product ever available.
Hahahaha this is so hilarious
Hey man, quick question-- if you were worried about the bulky items such as your clothes and bear canister, how come you went with the 40L? I hike and backpack in the Adirondacks a lot, and I am looking at the Kakwa 55L. I am also looking at the X-MID 2 from Durston. I currently have an Osprey Exos 58L and it's nice, but I'd like something a little lighter. I'm a seasoned hiker but new to backpacking as I've only gone on 2 overnights starting this year (I'm hooked!). Not an ultra-lighter, but looking into Durston for lightening up my kit. Love your videos!
At the time of publication the 55L wasn’t available yet. I now have both and prefer the extra room of the 55
Great review,. Did I miss the price of the pack? I went to Durston's site and it isn't there either. I apologize if I'm just dumb and missed it
The price is $250, which is about $100 less than any other similar pack with Ultra 200 fabric.
@@durstongear Thanks looks like a great pack!
Just started backpacking and used the Hyperlite 3400 and it was great, I loved how light it was. I am looking to buy a pack, I borrowed the last one, is the Ultra200 better than the material on the 3400, do you think it's waterproof to do you need a cover for this? I am new to this and not sure about companies, is this a reputable company I can trust to take on a good hike and not worry about it falling apart? Sorry so green to this, seem like the 3400 has been around so it seems like its built really nice and lots of great resources and reviews, this seems newer and fixes some issue like you said...Any other advise, thanks so much!
Interesting video, but what's the shirt/hoodie you are wearing? It looks comfy.
It’s the alpha hoodie from farpointe gear. I added a link in the description.
ULA and gossamer gear both have horizontal frame support similar to this
Try the Kakwa 55.
When are we going to see the 55L option review!
5x stronger than Cuban fiber?! Woah. I gotta check out those stats! When are the ultra 200 tents coming out?
what is the wall thickness of the aluminum tubes?
Dan Durston has been a little busy bee. He'll really build a name for himself soon.
You described two problems of the backpack. There are eight more problems. Outdoor sport backpacks sold throughout the world have five to eight bio-mechanical inefficiencies reducing a persons’ speed, endurance, comfort and generates fatigue. The spine is the center of human torso rotation that provides efficient human forward motion. The backpack is placed on the torso which rotates about twice that of the hips. Loads placed at the spine reduces waste motion which reduces waste energy. Loads placed at a distance from the spine generates thrusted motion generating waste energy required to return the thrusted load.
1. Backpacks extend to a person’s hips or lower eliminating one's inherent pace speed.
2. The width of backpacks causes gear storage side to side thrusting generating waste energy.
3. The depth of backpacks causes gear storage side to side thrusting generating waste energy.
4. Water is normally the heaviest load carried in or on a backpack. Placed at the side pockets it causes thrusting generating waste energy.
5. Hip belts reduce breathing by about 25 percent valuable for speed and comfort, not necessary for loads less than 20 pounds except to reduce side to side thrusting.
6. Water stored on shoulder straps generates side to side thrusting generating waste energy.
7. Shoulder straps not placed on the trapezius muscles pull the backpack forward and up with each step generating waste energy.
8. During the summer season, lack of air space on the back generates perspiration and elevated heat generating fatigue.
The backpack lacks frontal storage for quick access to emergency and preferential gear thus necessitating the removal of the backpack for access to gear wastes time. A balanced load, front and rear reduces shoulder stress and transfers a persons’ center of gravity forward for reduced energy expenditure carrying a load.
