I would NOT go with that titanium carabiner. It's super nice, but sized down, it'll still end up breaking. Edit: To expand on this; titanium is far from unbreakable. It's actually very similar to steel in strength, but lighter and corrosion resistant.
id be worried about fatigue in the part that flexes personally
@@thebritishbiker8197 yeah, minimum wall thickness of the part should be considered. Seems like a simple material change wouldn’t do the trick. The first design making it to production screams FEA analysis on any subsequent design update.
The carabiner is meant to keep the zippers together the titanium will be fine.
@@CarbonFanatic The original would have been fine as well. But people bend and move things in unexpected ways while in use and they break.
I would also worry about creep if used improperly
I would recommend against the titanium one. Titanium is quite strong, but it's also very brittle compared to other metals. Steel is better because it's more ductile than titanium.
Ductile is one of my favorite words. Say it put loud, really chew on it. DUCK-tile. Like gum
Titanium seems weaker than stainless steel per unit of volume
What about tungsten carbide?
@@CRNomad even more brittle, ceramics are very hard but can break easily. The durability of ceramics is a very complex topic compared to metals
Wow, I thought it was more ductile but I guess I was thinking of Nickel Titanium (Nitinol)
The Titanium carabiner needs to be tested for fatigue I think. When you're relying on metal bending back and forth eventually it has to break, especially if its not bent in the "correct" orientation all the time, people will inadvertantly put a side load on it when opening and closing it. Also people will open and close it a lot if they just fiddle with it. So personally I'd go for something with a proper hinge as thats less likely to fatigue over time.
I was thinking the same thing, metal fatigue will happen, and with it being made smaller it will fatigue even faster, and it will be an expensive “solution” that will need to be replaced again
when it comes to high quality carabiners I am surprised they have not looked at anything similar in the rock climbing space, most biners there with a similar style scaled down would work great for the purpose, especially with the hinge and nose design (or lock there of of a nose)
Especially since titanium in particular can be very sensitive to surface finish
That's a flexure joint/compliant mechanism. The metal barely bends in any one spot, but rather adds the minor bends of multiple parts of the piece together to give it a wider range of motion without exceeding the fatigue threshold for that given material.
Still, my issue with it is with the strength of the joint to resist bends on multiple axis. If you had magical machining you could carve a lip around each rib to prevent it from moving to the sides, but that doesn't exist, and if it did, it would be expensive.
im sure theyll do plenty of fatigue testing this time around, no way they would look for a replacement to a weak part without fatigue testing. im sure the solution engineering comes up with will be sufficient
*You need to add a center tooth to the closing bar !* (in legitimate carabiners, this part is called the nose and serves more purposes)
This is important to prevent the carabiner from being opened by pressing laterally. Even if it wouldn't break by doing that, normal use will pressure the carabiners to open (twisting them against each other will cause lateral force, which if unbounded will make them open)
This will also *definitely fix your breaking problem* (like for sure really) since the metal is breaking due to mechanical advantage. A tooth at the tip of the locking bar will ensure any pressure on the bar is:
- distributed between 2 different points (lowering the load on the joint)
- A shearing action on the joint, instead of a bending action. This reduces mechanical advantage to basically 0, so it would be basically impossible to break while in locked position
One thing to note is that this would not protect the locking bar from breaking if pressed laterally in opened position. This configuration of stress is inconceivable from normal use, and only really a problem for "finding out if it can break" type experiments; Since it requires a force to keep it open, and an other more different force perpendicular, to break it laterally.
The center tooth is a very common element in gadget keychain carabiners. One important change I would suggest from the standard is make it a wedge in the direction of actuation. (wedge would be visible from the top/bottom plane view)
This would help realign the bar on closing action and prevent lateral force on the last degrees of closing. By eliminating parallel stress concentration lines, I project it will also help the strength of the center tooth mating design.

(other direction of tooth is likely possible, but likely harder to manufacture)
You are an absolute champion for making that ascii art diagram
@@aniquinstark4347 I don't know if your comment was sarcastic, but regardless it made me realize there were problems because of markdown of the underscores. That's fixed now, thank you
@@syborg64 you are a champion ! Your answer is qualitative and so complete
exactly what i Was thinking. just written a lot more sophisticated
They have a tiny bit of metal that keeps it kinda closed. It is almost a tooth. if they increased the nub size and made a grove, it would function virtually the same. the problem is the hinge mechanism has too much give in the wrong directions, so when it is open, it seems to want to push to the sides as much as the back and forth motion.
I think I was the user who reported this issue to him and his team during Wave 1. There were probably others out there but I definitely had issues just immediately testing the carabiner no more than 10 minutes after receiving it in September (I was only trying to hook and unhook the 2 carabiners and it just snapped off). The LTT Support Team was very fast and courteous at replying to the issue and got me a new backpack ASAP. So far so good now. But was very happy to hear Linus is aware they messed up in the testing phase and have been working on multiple paths to find a way to fix the flaw they missed; but at the same time, keep the high quality feel. Can't wait for the titanium hooks (if that is the option you are going towards), and will definitely say their TMB warranty is so far very good.
It isn't a TMB warranty anymore
they can't have helped you, they haven't got the proper warranty that everyone cries about. how is this possible.
btw I'm being sarcastic lol
Did they even ship the Wave 1 yet?
@@topicslp3782 not that I’m aware of, I haven’t gotten my wave 1, nor have I seen shipping info.
@@joshuaschilling7374 I haven't gotten Any Info yet either
The 3rd one seems like the best option. Similar to current design, but more functional and cost effective. I worry of the open bottom of the titanium one
Yes i like that one the most too.
Yep, that last one seems more like a paper clip. The way it works worries me. It’s way too thin and is going to get stressed over time and break
That one scales all the way down to jewelry clasps, so would be perfect to size it to perform its given task, holding the backpack zipper closed.
I say cut off the bad zippers, put on two small key chain rings so you don’t have to risk bending metal. Sell different zippers that people can change. LTT logos that are magnets and stick to each other. Ltt crew member figurine zipper pulls. Colab zipper pulls. Turn the worst part into the best.
As others have mentioned, the titanium design is cool, but there's no real reason to make non-weight-critical items out of titanium, as it's only really impressive properties are strength to weight and heat resistance. My vote is the titanium design made out of a mild temper spring steel like 1095
Rust
You could always add a coating
@@gregistopal coating
Ltt merch in a nutshell, expensive materials on really meaningless things to try and justify the price besides saying "well r&d took 5 years"
I think 5160 would be a better option given the application, but I do agree.
The side ro side play in the titanium carabiner is concerning. Because the bend radius is not constrained, it could bend to the point of deformation, leading to a misaligned/cockeyed clip.
To*
that's not even the problem with it. if that happens people will just bend it back. and the nit happens a few more times, gets bent back a few more times and then break from material fatigue
@@anonym3017 The metal fatigue isn’t a problem compared to plastic deformation of the metal.
That sideways movement is very nasty for plastic deformation and causes it to be misaligned. Doesn’t matter if it has a lifespan of 6 months if it’ll be misaligned and useless within 2.
Both serious issues, however.
If you look closely it appears to do that just during his testing
@@aeonremnant except the metal fatigue is the entire problem.
If you can easily bend it out of shape you can also bend it back into shape just as easily.
But it'll fatigue and break after you did that a few times.
Linus dropping it before starting to talk about it is to classic
He wants to hold it with minimal finger overlap so it can be seen, but that ensures that it will slip easily.
@@gblargg Linus could paw the thing and he'd still fumble it.
WARNING LTT!!
Not a material engineer, but I am a Mechanical Designer for a company that makes trailers for the military.
Though I agree that the titanium carabiner looks cool, test it for fatigue where the lever bends. Even titanium will fatigue and break if bent enough times unless it's titanium specifically made for spring use. I'd run one or more thru a few thousand cycles of use to see if it cracks or breaks.
Additionally, the base eyelet looks to be a very thin material. So it may have little crush resistance and may not be that strong if something is hung from it (even though I know this is not its intent as you said). Maybe it's better/thicker in person and the camera isn't doing it justice but wanted to point it out.
Imagine it sized down. It’s gonna break
The transparency is appreciated, as are the steps taken to rectify the zipper issue.
If you added an extra loop on the inside of the carabiners, you could make it so they are usable with small padlocks aswell.
A normal zipper pull can be used with a carabiner, just clip it on.
@@gblargg but not a small padlock which this comment is about
@@ffwast You're saying a small padlock won't fit a normal zipper pull?
@@gblargg No doofus, everyone else is talking about carabiners.
@@ffwast I hope you're joking because if they're replacing the zipper pulls, everything is on the table. The overall goal is to satisfy people's different needs, literally as parent is commenting. Why limit yourself when you're going to be redoing the pulls?
Having used carabiners for my keys for a long time i come to like the wire carabiners most. just out of strenght reason. They have never failed me and are still as strong as on the first day.
This!
Plus the design is super simple since the wire latch is, itself, the spring that keeps it closed. Neat bit of engineering. The lobster claw clip would also be a very viable design at scale.
No one explains why it's necessary to add carabiners on every single zippers and it makes no sense to me. Why not just one on a strap or inside the bag? Do you really have that many keys?
@@Neavris I would love to see more side mounted hooks, camping kit ( Hatchets, knifes, light bags) would hang well one them, on zippers, not sure how they would be useful.
A little nice to know about the ISO 9001 certification, I does'nt mean the product is high quality, was made right, with the right material or was well conceptualize. It's more of a testamony that the compagny with the certification has put in place strict quality control guidelines and procedures. So it's up to the company to do what they put in place or not. No doubt that the backback and screwdriver are high quality, mistakes are totally normal!
Thank you for the transparency, that's why I love the WAN show!!!
You are correct. ISO certification means the company has sufficient guardrails in place from a quality/project standpoint throughout the product lifecycle. A supplier being ISO 9001 certified doesn’t necessarily mean a product meets a set strength or performance requirement. It dictates the supplier has all of the systems in place to ensure a product they produce meets the customers requirements and has quality systems in place to ensure the product is built per the requirements.
As a 9001 auditor I like this,
Generally it means they do what they say and operate as a business in a reasonable way with accountability.
ISO certification is kinda just a shakedown. Doesn't really mean much.
Came here for this… ISO 9001 is misunderstood, and it’s pretty clear that Linus doesn’t understand it either.
It means "we write detailed labor reports where none of the employees actually take the required measurements, they just say that it's within tolerance"
I would go with a wire lock-in one. I know you’re saying it’s not for hanging things it I guarantee you people will use them for that. Good ethic taking care of your customers. Keep up the great work.
Exactly. It is absurd to include a carabiner design, or anything that looks/function likes one, and not expect that people will treat it like one and try to hook it to things/things to it, that it isn't designed to handle.
@@curtisbme Yep. I don't see why he thought people would use it like he does (interlock two to stop the zippers from coming undone).
@@attomicchicken I don't even think I would have thought of that use because why would you do that? Has anyone ever had a decent backpack (or any bag) where the zippers would just open by themselves? I'd find hooking them together to just be an annoyance to do/undo every time for no benefit.
@@attomicchicken to prevent people opening it and stealing stuff while on your back
@@MGMutt Oh for that? I like to front carry as you would do a toddler.
I feel like if you put carabineers as pulleys, you have to expect people trying to hang stuff off of them. They should be durable and stay closed even under some side load.
There have to be better options for that than the ones shown in the video.
I know Linus really likes the Titanium one but honestly that was probably the worst one he showed. Least likely to stay closed, most expensive, and easily the most likely to break. Those wire ones last forever.
I use a small s-carabiner already (the first alternative shown) and want to say that it’s super great. Either end loops a zipper, and a center bar rotates to lock the carabiner. It’s small, looks cute, and the lock is easy enough to undo while also being small enough to deter pick-pockets trying to open
Yeah I have a stainless niteize s-biner on my keys ands it's great. I had one of the plastic ones on them for years and never had an issue. I just decided to upgrade when I got a different style of key with a new car.
EXACTLY! Linus should've known about this before he made custom zippers just to close around his badminton rackets lol
Who woulda thunk a backpack would have been such a complex product launch? I'm definitely learning from your experiences.
Just curious, what are you planning to produce?
Main focus is a Terpene pain relief salve lovingly called Snake Oil, inspired by studies on the most active components within essential oils. I'm a massage therapist by trade, so as you may imagine, there's a wide range of relevant products out there that I've sold small-scale. Each iteration helps you become more imaginative in the diverse ways a person can misinterpret or misuse every facet of your product and packaging.
Numerous peer reviewed studies on pubmed for isolated Terpenes. Do some research on the gabaergic properties of Linalool, the cannabanoid properties of Myrcene and Caryophylene, and the immunomodulatory properties of Bisabolol and get back to me on the pseudoscience. Isolated compounds are easily standardized with measurable quality consistency.
You're generally spot on though, yes. Lol.
@@CygnusXUno essential oils are very good if you’re realistic about what you expect them to do, like “this oil has disinfectant properties” for example. They’re not gonna do any wild stuff like cure cancer but one of my parents uses / researches essential oils and if you’re sane about them they’re great. For example something found in early stage trials recently is that certain essential oils can break down antibiotic resistant coatings on mutated viruses allowing the antibiotics to destroy the virus once the coating is destroyed.
People have a habit of severely underestimating the complexity in the development of everyday products.
Even if it's just another version of something that already exists.
Leaving a post here for an update whenever it has one
It's really cool how much you care about the quality of the products you guys put out. It just makes everyone who got products feel more like a part of a community
Honestly as someone who has issues with hand strength, I prefer when zippers are larger than normal. Also the smaller you make a carabiner the more fiddly it’s going to be regardless of its quality.
They shouldn't be making them so big that it looks bad since it is easy to add on your own tabs to make it easier to open zippers. I've had success with adding them to help my dog open zippers and know they'd work well for bad hands too. Plus they already have a clip which means your added tab just needs a loop to be added on
@@zebraloverbridget I think it’s up to your personal opinion over whether or not a larger carabiner looks bad, personally I think it looks fine.
I don’t know if aesthetics is more important than being accessible.
I do agree that I am excited for the carabiners in general because it does mean that I can clip on a tag or something to make using it easier to use.
Make it out of steel, make sure the sized down version has the same thickness, and add side walls so there's no side to side play.
You can also machine a little hook into the flexible part so it cannot be pulled open, only bent backwards
Also, had no clue those things are for keeping the zippers shut, I use mine on my old backpack for holding things like a water bottle.
You will have to replace the backpacks zippers... Most probably users will brake the slider hook if the try to change the pull tab them self. Even once, properly done, will fatigue the metal. Especially if it is made by a zinc alloy. Titanium in that dimensions is a risk. Your best chance is using a ferrous alloy.
I agree that asking people to replace it themselves is asking a lot. Even if they successfully replace it without it breaking, that loop on the actual zipper will be weaker and its already a breaking point, especially on waterproof zippers. I'm not sure how stiff the zipper actually is but that piece breaking is really common on things like Yeti style soft coolers. I'm also curious what their response will be to those people that break it, will they they get the whole bag replace or will they not be covered because they broke it themselves.
Honestly, you'd probably be better off in the long run if you created a small ringed component to replace the carabiner with. Then having a carabiner which you just link onto the ring.
It would have saved a lot of time and money for replacing the carabiner if and when it breaks, since your process is no longer stressing the metal to replace it, and instead just replacing the carabiner on the loop
I think this is the best solution. Then folks can put whatever the f they want on there.
yes, heavy duty zipper, put the carabiner/padlock/zip tie through the hole in the zipper end,
LOL Your backpacks STILL HAVE THIS ISSUE! You have to be kidding.
The dreaded “that’s not really its intention” haha, love how much attention to detail you all put into your products!
A great quote for user testing (mainly for UX) is “legally permitting, give your product to a 4 year old, and if they can’t figure it out within seconds your product sucks, because they’ll just give up”
ISO standards are great a minimum bar, but they don’t account for the fact you can’t standardise a user, ie test EVERYTHING.
I've had the backpack for several weeks now. I'm satisfied with their response to the issue, but kinda annoyed at their insinuation about it being largely due to misuse. From the moment I first opened the bag I knew it would be a problem. The way I naturally operate the zipper puts sideways pressure on the carabineer about 50% of the time (comes down to which orientation it ends up in my hand). Even with me being conscious of the issue since day one, two of my carabineers are slightly skewed. Additionally If you have an LTT water bottle in the dedicated position, it takes a decent amount of force to close the bag, enough that I wouldn't be surprised if it snapped one day. I've basically had to retrain my brain on how I've operated zippers my entire life in order to prevent breaking it.
I appreciate your honesty!!! Refreshing!!
It’s very very cool to see folks have the integrity to address this right away and commit to fixing it for everyone 😊 stoked to get mine soon
This is greatly appreciated, not often companies address these issues and says a lot about you that you are. Thank you
I LOVE that you are admitting AND showing the problem and accepting responsibility to fix it/change it.
Thanks for always being transparent, I feel like every time you're completely transparent with your audience about something they all start lighting their pitchforks and want to burn you at the stake, lol. I appreciate that you want us to know everything that happens in these situations and I hope that the complaints that you get every time don't change how you feel about everyone having all the knowledge they need to make an informed decision.
Thanks for showing the process, super interesting!
I kinda don’t like the titanium one. The side to side wobble seems… not good? If it locked in place then i don’t mind at all.
For reference i haven’t got a pack yet, but I’m waiting to order one soon :)
Re: Staged Orders, I think that you guys should ship those as-is, but include information about the care-package until they are ready, and then ship care packages as you get them to the following waves. I think a lot of people who ordered the backpack when it launched would not mind the possible faulty carabiner existing on their bag for a few months until the care package with new pulls comes in over waiting even longer for their backpack
I agree. I preordered the Killswitch case for my Steam Deck and they're replacing the magnetic kickstand and case with a mechanic interlock for free. Only orders that got out in the first 24 hours or so were delivered. Everybody else has to wait until Q1 next year. I'm glad I have mine now. It's trivial not to use the kickstand for a few months. I'll happily receive my Wave 1 backpack and replace the pulls myself if it means no more delays.
It's okay Linus, I have expensive taste too 😆
I'm surprised a nice little key ring and a near standard carbineer wasn't the choice?
ahhh teething problems. Welcome to new product design. Very, very stoked and proud to see you acknowledge the issue and are going to rectify it on new bags and offer fixes for the existing 'in the wild' products. Well done LMG for being proactive. (as an aside, I too feel the one-piece titanium carabineer will fail from fatigue over time)
I JUST had this issue last week so I’m glad it’s not just me
For tech bags I've seen zippers that just had loops cast into the zipper that interlocked when side-by-side and a padlock or keychain carabiner easily fit into.
Just a side note... If you make a notch on the upper side of the lever and then make the negative of the notch on the receptor, you can probably make it much cheaper... If you slant the bottom of the notch it will automaticly stop the lever.
great customer support as usual from LTT
I like the first one, those are also the most satisfying ones regarding fidgeting imo :D
The Rejected S carabiner looked sooo cool!
I love how so many people take issue with y’all being transparent about as much as y’all can.
My main carabiner i have on my key chain has a little lip in the middle of where it is in its resting position which gives it extra strength when closed
I use those Sbiners on all of my backpacks. Each zipper has one. I ride motorcycles and using them keeps my zippers closed together and keeps people from quickly opening my bags in crowds or airports. I love them.
The metal ring where the pull attaches to the zipper looks thin too. Many zippers wear down and snap. If not breaking the zipper head hook that keeps the pull on.
On real carabiners the clip has a slot that overlaps the body when it's seated to prevent lateral movement in the closed position. While that would make it less likely to be bent over when closed, the hinge would still need to be beefed up to survive anything heavy hanging directly off it.
The camera work in this clip is top tier
Honestly this is incredible transparency and honesty. Major car companies have to be forced into recalls because of safety. And here linus is taking a loss just make sure little clips are up to his standard. Bravo!
My backpack just arrived a couple days ago and it came with the original carabiner pulls. I haven't used it much so they're still fine, but any updates on the replacements? I see this video is dated about 10 months ago.
It's nice to see you guys at LMG go out of your way to remedy an error, regardless if it was foreseeable or not. It's not common to see any company prove they... carabineer.
Glad you’re working on a fix, but I would appreciate if the remaining wave 1 backpacks could still be shipped since they were already delayed due to shipping and this fix sounds like it could take a while, which would mean even longer wait times than originally advertised. You can always ship the fixes later and give us the backpacks when they’re ready to ship.
In fairness, that does mean double the shipping costs so I can see why they would be keen to avoid that.
@@orangejoos the backpacks cost an order of magnitude more than whatever a fix kit will cost to ship. It would not be doubling their shipping costs.
@@UnsweetIceTea Plus it will reduce their costs of having to do the swap. User does swap = less of their time.
@@gblargg Yeah but if the user does the swap and breaks the zipper = user fucked
How about adding a solid loop on the back side or the bottom of the carabiner to allow them to be lockable with a padlock?
A padlock on a backpack is like putting a bomb proof door on your shed
@@201bob some people want this feature so it's not constructive to disregard a solution entirely, and just like any form of security if someone wants to get into it they can. Just like the front door on your house; no matter how many locks you have on it there is a way to get in.
In the case of a backpack sometimes it's not just to stop people getting into the bag but to know if someone has been in the bag. Take the example of putting it into the hold of an airplane, you know the padlock won't stop someone who really wants to get in from getting in; however you will be able to tell if someone has been in your bag by the broken padlock and tampered or seen any documents.
@@elliottwhyman2608Ok, So.
If you are taking a bag on an airplane, And you use a padlock then the security there CAN open it with a key.
Unless you are using a padlock that is NOT ALLOWED TO BE USED.
There is ONE key for all travel locks.
They are UNDER FIVE DOLLARS to buy.
This defeats your ENTIRE POINT about how itll show if someones been in your bag or not.
I could legally purchase the key, Open your bag, Take what i wanted, Relock it.
Even if i DIDNT have a master key because you decided to use a lock that was NOT ALLOWED [which if discovered it will then be cut off and your bag will be searched thus making the lock REALLY STUPID to buy] then there are SEVERAL non destructive ways to still open it depending on the lock.
You most likely wont be taking a big heavy top of the line lock that costs more then the fucking bag and putting it on your backpack.
You will most likely be getting a cheap garbage lock that could be opened by pulling on it hard enough.
There is NO reason to buy a lock for your backpack. It stops no one, It CAN AND WILL be opened.
CLIPPING THE ZIPPERS TOGETHER IS JUST AS GOOD as any cheap ass lock youll put on your bag.
You would NEVER NOTICE that someone opened your lock with a master key.
EVEN IF YOU DID then what? You cant do anything about it anyway. Save your money. Dont buy a lock. Use the fucking clips.
I hope this helps you comprehend how stupid it would be to put a lock on it.
Just like it would be stupid to put a bomb proof door on your shed.
@@201bob A small security is better than none id you ask me. Plus the textile is supposed to be quite rugged against sharp objects, so it does make some sense here.
@@201bob I advise just getting a pack of colorful zip ties. Serves the same purpose of travel security tamper evidence and also cheaper.
I've been using a titanium key clip, with a similar design as the one he's shown for about 6 months now. So far it's stood up perfectly so that design gets my vote of confidence.
Ooh mine broke so fast, I'm glad you guys are taking action
If you do the titanium one it would be better to go with a tool steel or spring steel, rather than titanium. Personally, the 3rd one is the best option to me. The S isn't bad though, and having 2 separated clips helps more than than you think.
Just received my bag in Australia today. Thanks!. The zips do look really cool, and i only plan on using them as zipper pulls, and occasionally hanging my security card and galaxy buds on. My current bag has spring type ones with velcro from server install kits :) very impressed with the size and looking forward to flying with it next week. FIFO worker, so should get a workout in the air.
My wife’s SwissGear backpack had the same problem. The rest of the backpack is “bulletproof” but the convenience carabiner (for keys, etc.) broke soon after starting to use. Replaced with aftermarket rock-climbing grade carabiner and now no problem.
Just a FYI: zippers are easily opened with the help of a ballpoint pen without leaving any marks, you press the ballpoint pen into the teeth of the zipper right behind the slider, and them move the slider back a bit and then forward, this disengages the teeth and you can easily open it by hand.
So never rely on them to keep someone out.
I think the only way to prevent this kind of attack is by fixing the slider in place, some brands of suitcases do this.
okay but where do you find that last carbiner. I got one from an old employer and want another unbranded one because yeah, compliant mechanisms are cool.
Probably AliExpress.
so the issue here is putting side force onto the carabiner while it is closed, why not add a bit at the tip of the hook that registers into a slot on the top of the clasp, where side to side movement is supported by both the top and the bottom of the little movey bit?
Modifying the top of the hinging bar where it meets the top stop of the opening with slots so that it meshes in a way could eliminate side to side play and severely strengthen the hinge
Always very critical of you (because I like you guys). But I like this very much. Good job
Make it a free order from the LTT store for everyone who bought the backpack. No need to waste money sending it to people who don't care.
As much as i like the design of the titanium one I'd go with the choice of reinforcing the sides on the current design or use the design of the one with reinforced sides. I think it fits the bag better and should up more than the scaled down titanium one
That Titanium is a demonstration of a compliant mechanism as well, which is neat
Man just another reason to love the trust me bro warranty
Like somebody already mentioned it, just add a tooth to the upper part of the closing mechanism and a channel that accommodates that tooth. The cheapest and most effective way to prevent side to side movement and braking without much altering of the initial carabiner design.
That two-way caribiner looks like a larger one from keysmart. Love their pocket-knife key organiser thing.
compliant mechanisms are so cool
there needs to be support for the carabiner top side where it opens and closes so it doesnt flex side to side, what if you hang something on it and it just falls off because its hanging on the part that opens
You should use buckles, they are super strong (plastic ones could even be stronger than metal), and look way better than entangled carabiners.
Another option is simple as loop and "button" or soft shackle. It's cheap, minimal and robust
Every small carabiner will break easily. Even expensive ones made by climbing companies. If you want to use them you need consider them dispensable and expect them to break form time to time.
Linus I got a new ltt bag and you are still using the old original carabiner and wondering how/if a replacement was intened
I have a small "zipper sized" S type carabiner on my keys and I love it
Is there an issue with having the moving part of the carabiner at the top be shaped like a bracket [ and have the fixed top have a rectangular peg so it just slips over it and it would prevent side to side motion unless force bent the metal of the side walls of the bracket?
[=== if the bracket had 3 walls and an open face for it to fit over the fixed part while closed it would have an end position to hit too for the spring so it can't open outward
I'm not sure what the best solution is but I know I really like the carabiner zipper pulls. Being able to have something sticking out of the backpack just a little while still being able to close it is really nice. Like others have said, a way to attach a padlock would be nice, but ultimately I like the carabiner. Hope you guys find a good solution.
Any update on the new pulls? Was just gifted a new backpack and it has old pulls.
I would love a connecting clip that DOES allow easy replacements in the future. I like the original design, and would happily keep a few spares on hand if able to be ordered separately and replaced. A simple S clip design would be sufficient, IMO
This is my favorite idea of the bunch and I really like the titanium carabiner
You can get little clip-on zipper pulls for absurdly cheap on Amazon. I've bought 10 for $10 years ago; they connect with a little clip so you can take them on/off as you need and they last long enough so that even though the clip does eventually start fatiguing, I've only replaced 1 in 5 years of everyday usage on my backpack. The S types are a little more expensive, but you can buy them in bulk from AE if you really wanted to.
I remember seeing a post about this
I bought that exact titanium carabiner 6 months ago. Gave it to my girlfriend as she broke a previous carabiner that was expensive and supposed to be strong. This titanium one has not given her any problems. She uses on the car fob to connect and disconnect to her main key ring.
Option 3 is cool cause it feels like a zip puller and is also a carabiner
yo the compliant mechanism titanium carabiner is SICK
Carabiner-gate!
Any updates? I've got the backpack and will probably just keep it as is, unless I break one by mistake, but am interested in the process.
@LTT I'm sure y'all have done all sorts of research in regards to this remedy but incase they haven't come up in your initial searches you might check out hk-style carabiners or snap hooks. They're designed for rifle slings, look pretty nice and they're tough as hell - plus you can run a lock through the hole in the side of the clip.
I've used one on a keychain (among other things) that's seen everyday use and abuse for the better part of fifteen years and is still going strong.
Maybe a bit chunky for the application but the design could certainly work miniaturized.
Do we know if they have upgraded before I order one?
What about something like a button-snap-style (or even magnetic) clasp? If the goal is just to keep the zippers together and prevent someone from quickly yoinking your bag open, that might be a durable option to consider.
those are much easier to get open vs carabiners clipped together
@@yashdes1 Yeah, that's fair. Probably wouldn't provide much additional security. The only pro on that front would be if there were some way to allow users to add a small lock to it (for instance, if the snap fastener had a hole in the center where the shackle of a lock could go through - I feel like I've seen that before). Might get too bulky at that point though.
5:19 - in my experience with small carabiners, the kind with this type of clasp seems to be the most durable.
I like the design of the original the best tbh, but the titanium is really cool too. I worry about fatigue tho
If it's that thin on the big version, the scaled down one will snap instantly.
I’d like to see some sort of groove on the tip that it seats into to help avoid side play if it can be done cheaply in manufacturing.
Good thing the backpack has a warranty!!
Well that's why most carabiners come with a little U shaped notch and a fin at the latch so those are the ones taking lateral force instead of the joint. The titanium one has the same problem. For opening it has it's own loop to stop itself, but by not having anything to prevent it from bending itself sideways i can assure you people will be bending it way past its limit and breaking it.
to prevent the side to side wobble something like a keyed nose would be recommended, I am a rock climber and you will see something like that on any solid gate carabiner, this way the tip of the gate is structurally sound on both ends, a lot a structural rigidity for little cost, without it I feel like regardless of material it will be off center eventually
Yeah carabiner that doesn't lock in place is just a bad design
Those S carabiner are awesome. I have a bunch in multiple sizes and they are strong, durable, and I think they look good.
I've used the little S-clips as replacement zipper pulls and they look "okay." it's better than ruining the zipper to try and force a new pull in, and looks better than a paracord replacement pull.
I like the clasp on the S-beaner can the LTT be redesigned to use the spring steel clasp?
Did this ever go out. I have a bag that from the the original type zipper pulls. I have been trying to use them lightly but I can tell that some of the hinges are close to going out
I also never heard anything about it, and also have the original backpack.
I wish Linus made more products, his attention to detail, demand for excellence, and passion to do right by anyone who supports him is the pinnacle of customer service and product design.
The third one he showed looked to be the most structural sound of them all.
