It's the truth.

Thank for the tip also won’t it chimp your head or ear but this is why I’m watching tips

I thought the bear was gonna attack him when I saw him right there

I’ve used this bivvy many times. By itself in the summer and with a sleeping bag inside for colder weather. It absolutely increases warmth but I wouldn’t say it is noticeably breathable. I always have a small amount of condensation on the inside of the bivvy but overall, I think it’s great and usually bring it as a lightweight solution to increasing the warmth of my sleep system. Having said that, I once tried an emergency Mylar sleeping bag and the sweat buildup was insane.

you're cold when you use it cause it's not waf below 60F, unless you tent it off of you and have it around a hammock. Then it can handle 50F, if all you have is cammies and a beanie. Thats all. It's too small, too, since it's sized for little Asian guys. A much better deal is the $95, 1.5 lb Trifecta bivy from 2GoSystems. It's much bigger, has tie offs for use as a shelter, can be worn as a bivy, two full zippers. If you envelope it in a couple of taped together drum liners, it'll let you sleep ok at 40F, in cammies, gloves, sets of sock lliners, shemagh, beanie and unlaced shoes, 6" off of the ground in a hammock, with debris kicked under the envelope to stop air from flowing under you. That's all you can expect of a layer of tyvek, folks. You CAN add dry debris between the bivy and the envelope and get it down to 30F, add hot rocks or hot water bottles to the footbox, and get it down to 20F, for 2-3 hours at a time. Dont expect miracles out of a thin piece of tyvek, cause you'll be sorely disappointed. any place it touches you will form a cold spot. It does nothing to stop heat loss from conduction to the ground, It doesn't stop much wind and if you let water puddle up on the tyvek, it WILL soak thru, eventually.. If you dont envelope it in some sort of other barrier, forming a layer of trapped air, you will get some condensation of your body moisture inside of the bivy

So glad we have these video forums

Pity about the background noise

They need to put someone with my training on that show

No compass?

If you wear a big jacket and touch the Mylar it wont trap the radiated heat, there has to be an air gap.

Most of the heat lost through head.... Yes because usually we don't cover our faces.... But otherwise that's just a urban myth....

I carry a couple of packs of chemical hand warmers in with the SOL.

Thank you. Have you heard of Blizzard medical gear. They have triple layers. But not breathable. I'm not sure what is a better product - the SOL or Blizzard. The SOL being breathable seems more favourable

I rather not use it. It below freezing and i was so colded that hyperthermia kicked in and i was shivering so bad. The only thing that same my life was the heater of my truck. I rather just carry the proper sleeping bags

Yup ..bring a heavy mill large trash bag ..fill with leaves / debris..make a bros bed to lay on

It’s a breathable bag. There are cheaper ones that are not

It's incorrect to say that the majority of your heat is lost through your head, that's an old myth that has been proven wrong

This guy is an idiot

I do use this over my sleeping bag - but only in cold (below freezing) and/or windy conditions. Better than a liner because it blocks wind and can be used in more ways than a liner.

I love these bivys... I brought mine to use like the military bags as a outer liner but never got cold enough to actually use a sleeping bag inside of it... Of course i don't camp in winter.. 😎

I slept in mine in October instead of my sleeping bag and i kick it off but we had reflextics down as a mat on the floor... We stayed really warm warmer than the first year we went camping in the same area...

I use a jungle bag and S.O.L. outside w/t wool gloves and hat - comfortable at 38 degrees… you MUST INSULATE FROM THE GROUND !

The amount of bs is insane

That you for this! With the popularity of ultralight-everything for extended ultra-endurance races (running or cycling) what would be the best way to use something like this? You do a good job of explaining how it works and what people get wrong with it, but: IS there a situation that this is usable with an ultralight sleeping bag or sleeping bag liner (whether inside or out)? If you were taking on a 5-7 day adventure race, where you sleep when you can and ounces matter, would this be in your bag or would you opt for something else? Thanks for your videos!

I read all the reply’s, I think you got it exactly right. Test on your deck is fine. A real life test in the mountains in cold temps is best. 1 question: lots to say why no good with a sleeping bag in side. But what if it was used as a liner in a sleeping bag? Condensation might or might not be a problem? Although this bivy is intended as emergency if no other bag is available. Yes? I keep one in my vehicle. One in my 72hr bag & 1 always in my day pack. I’d sure like to see a how to use video from SOL done in a real life situation. Thank you Justin! Much respect to you for your Alone adventure and for your dedication to Veterans and active duty boys also! I kee

No offense intended but doing a "test" of the bivy on your deck in daylight isn't going to prove much of anything. I wouldn't trust this thing to protect me in the wilderness without seeing multiple "tests" overnight in real world conditions. In the meantime, if you're going into the wilderness, carry at a minimum a good sleeping pad and a bag or quilt rated for the conditions. Throw in a good tent while you're at it. Carry a reliable GPS device and a personal locator beacon (PLB) too. Save the SAR guys the trouble of having to look for you when you get yourself lost of injured.

ruclips.net/video/Nk_PM_XD2EE/видео.html SOL literally recommends to use a sleepijng bag with it!

You were clear you don't like acronyms 😉, but have you tried BRACE? I feel like it offers a little more information to dynamically respond to survival scenarios where thermoregulation is an issue. It stands for Breathing, Radiation, Air Convection, Conduction, and Evaporation. Like the vid, thnx

I no have to say I respectfully disagree. This BIVI is supposed to have an insulating layer inside. The key is using an appropriate layer for the conditions. Sweating is simply because the user has used too much insulation. But I know many people who regularly use a sleeping bag inside these and have zero problems with condensation. Too much insulation = sweat. Too little = cold. Exactly the same as clothing. We all know to take off layers if we start sweating, or put on layers if too cold. Not sure why people think it’s any different when laying flat inside a bivi bag.

Good video. Make more videos

very nice review!!!!!

Think I will just stay with their solar tarp for emergencies. That way I can open up briefly to let out condensation.

I guess, you could lay on top, of your extra gear?

Excellent job man. You've saved me some heartache here.

You’ve come at this from the angle that answers my questions. Pad no pad, clothes no clothes, blankets no blankets… etc. I’m putting together a bag for my wife, travel nurse. Extended distances from home at times, 100 plus miles. Looking for fool proof items that workout weird directions.

Yup... the discription says 'satire'.

Sorry but you lost me at acronym

Awesome tutorial video... well done !!!

"alright so i'm in the bivvy!" 😂 for real though, great review and valuable info! WEEP! won't forget that one. thank you so much for your time and energy

Hand to hand combat with a 300kg grizzly bear in real life never ends well.

👎

What a fuckin idiot. You go hug a godamn grizzly and let me know how it goes betch.

It is not a sleeping bag except in an emergency. It is a bivy sack, meaning you need an insulating layer, unless it is already warm and you're only trying to stay dry. If you dress properly for the environment and activity, such as you are, that may be sufficient. Or, possibly the addition of another jacket. I have used the SOL Escape Bivy with a jungle sleeping bag and fleece, with the temperatures down in the 20°, while hunting in the mountains of Nevada. Stayed warm enough and dry. You have to look at it as part of the solution.

Hahahaha bitch please !!

For emergencies, these can be used for bare minimum survival if used correctly, as shown. I carry one in my survival pack along with two "space blankets", basically to entertain myself before freezing to death. Kind of like carrying some fishing hooks and dental floss. Purely for amusement the next day if I survive the night.

Holy shit Justin is that actually you? I’ve just finished watching Alone a few weeks back...what are the odds. Just wanted to say that you were a MASSIVE inspiration to me and I’m sure a lot of other people watching. I really mean that. You didn’t win the show but you’ve won our hearts man so thank you. What you did out there was genuinely something else and a selfless act. Hope you’re doing well, respect from the UK. Stay strong 💪

Natural selection.

Do I hug him above his shoulders or below? I’m 5’1’m but what if he’s taller than me? When I let one arm go to stab him will he get mad? Where do I stab him? What if I don’t have a knife? Can I kick him in the balls? What if it’s a girl bear? If it kisses me do I have to get a rabies shot? Will stomping on his toes help?

Scratch him behind the ear, he'll just go to sleep. Right after supper.

Ya right MAN 😅😅😅😅😅 PEOPLE ,! DO NOT DO THIS YOU WILL GET HURT .
