S.O.L. 90% Reflective Lightweight Emergency Bivvy

I was surprised by how small and light this bivvy roll was when it arrived (I ordered two), and I immediately opened it up and tried it out. It is roomy enough for a 6' tall 200# man, and you could probably fit two in here in a dire pinch. I pack these with me, essentially as emergency sleeping bags/shelters on all outings, since they're so small and light. You would be VERY glad for this if you were SOL without a traditional blanket or had to remain over night in the woods unexpectedly. This does not replace a tent and sleeping bag for sure, but it will probably keep you from dying of exposure in pretty low temperatures, and you may have this when you forget to pack a safari tent when your car breaks down in the snow.In a wilderness setting, I would insulate under this bag with whatever brush I could find and then around the bag with dried leaves and then wrap up in a second bag, which I also bring along, and that would be VERY effective to keep you warm and dry at night. Ideally, you would want to get under cover of shelter and off the ground. Still, this bag would help cut the wind and at least keep the wind from evaporating all of the moisture from your skin and chilling you further. It might even help if trapped on a ski lift for a week with wolves roaming below, just don't take your glove off and freeze your hand to the safety bar. Even in warm weather, this would be helpful for someone going into shock, if their core temperature began falling.This product is far superior to an emergency blanket, because if you've ever had to use one, you know it's like covering yourself with a 4' square of tissue paper in gale force winds. Drafts get under the blanket and it's not nearly as water resistant since you are exposed where your undoubtedly poor wrap job "seals" around you.These would also work wonders to prevent hypothermia on a hiking in the cold, if someone fell into water. You could get into this bag skin to skin with someone to save their life, or just get frisky. You could use this bag to: carry light important items, like food; collect water; signal to rescuers; cut open to create a heat reflector for a fire (why it's good to bring a sucky emergency blanket along also); create a water still or rain collector; reflect heat AWAY from you when you need shade shelter in open sun; line your pack and place clothing for some water proofing when crossing a stream/river; cover an amputation stump to prevent blood loss or seal a sucking chest wound; create a cheesy Halloween costume as the orange ghost; or make a wind sock in your yard.5 stars for value, good strong material for what it is, design/roominess, superiority to an emergency blanket, re-useability, extra space in stuff sack for quick roll job or extra items, and life saving potential for low cost/space/weight.

I'm a big fan of this little bivvy. It is about 2/3 the size of a soda can and only weighs a few ounes, which means it's not much bigger and doesn't weight much more than a regular emergency blanket. But, it covers your entire body and head and therefore provides a lot more protection than a regular emergency blanket. I personally own two of these. I always keep one in my day pack which I use for everything ranging from short casual hikes to hiking rim-to-rim at the Grand Canyon. I also keep one in my emergency kit in my car. I've since purchased at least a half-dozen of these to give as gifts to my fellow hiker and disaster preparedness friends.I'm also a fan of the Adventure Medical Kits Survive Outdoors Longer Escape, Bivvy Breathable Blanket (I have bought two of these for our two bug-out-bags for emergencies that might happen while we are home). But, it costs more and takes up about 6 times the space. And, while I would recommend this one for overnight hikes in areas with nice weather, more serious emergencies, or longer-term use, it is not suitable for a day pack given its size and weight, or cost effective if you need more than one or two.But, this little bivvy has a high cost/benefit ratio for those sorts of things. It is a small, light weight, inexpensive, and worthwhile addition to any day pack or emergency kit.

Finally used this product, purchased as an emergency use item. Caught in the rain during a hiking trip and this combined with a hammock and tarp made for a fairly comfortable night sleep. It made it though the night but did rip when getting out in the morning. Even for a one time use items it exceeded my expectation

This is a great product but for emergency only. It's very lightweight. It's very small as the size of your fist and can be stowed in any pocket. This bag is roamy enough to be ducked in it with all of your winter alpine cloths on and the material is strong enough to widthstand damage done by stepping in it with skiboots. It's not the same as an emergency mylar space blanket because 1) it's a closed bag with far better protection against outside wheather element (wind, snow, rain) and therefore offers far better heat retention (but at the expense of increased vapor condensation and sweating) and 2) it's much more silent when sleeping in it. It's perfect as an emergency shelter and I wouldn't use it on a regular basis mainly because it's not breathable (there are plenty of other products for that usage). The bright orange color is easy to spot while being outdoor to signal for an emergency to other people.

I just received two 3.8oz. SOL Emergency Bivvys. I am very pleased with my decision to purchase these emergency sleeping bags. Adventure Medical Kits generally produce quality products but my decision to purchase this particular item was influenced mainly by the positive customer feedback on this site. I haven't had the opportunity to try it out yet but I'm fairly certain that it will function as advertised. What I found most appealing about the 3.80oz bivvy is the size. I knew they would be small and lightweight but I was amazed that I could easily fit both into my hand. When it comes to humping gear around the woods, the size and weight of the items in your kit matters. Ounces = pounds and pounds = pain. I will stow this extremely lightweight and potentially lifesaving bivvy in every bugout bag/kit I own. I will purchase more as well.
