Adventure Medical Heatsheets Emergency Bivvy - 2007 BCS

Something like this is a really inexpensive way to maybe save yours or someone else's life. Or at least make a night stuck outside much more bearable. Can be thrown into any pack for any trip. I've only used it once after hours of shivering in my mummy bag in a snowcave, brought this out, threw it over the bag, and was dramatically warmed.

I picked this piece of gear up for emergency situations and thankfully have never used it. Its light enough to always have with you and packs down small. I liked the fact that their is extra room at the top of the stuff sack for adding additional survival gear. Pick this piece of gear up. You would regret it.

used it when overnighting at 9500 feet in 30+ mph winds. Very warm, very durable, won't ever leave home without it.

I usually find room for emergency gear in my large pack, but often that hear doesn't make it into my day packs or camebaks.

This bivy is simply too small, too light, and too effective to leave behind. It fits anywhere, weighs nothing, but can be incredibly useful in a bad situation.

When I was in Alaska last summer, I had one of these bivy sacks on my person during a hike in the Brooks Range. Its light, compressible, and able to be repacked all the while being warm. It's worth the cheap price for survival.

Have to agree with al the comments below. Not had to use it yet,and hope not to, but looks well made, is really small and light too. For $12.50..its a pretty good deal.

this worked well for an emergency situation. I have used this on a survival campout when in scouts and it worked well but dont plan on using this as a warm substitute for a real sleeping bag the durability for it is questionable

I hope to never need to use it but I carry it in my pack. It weighs about nothing and is small enough to store in pack and forget about it. My wife also has one in her pack. It is well worth the the price just knowing that if need be it could save your life.

Great piece of "OH SH!T" gear. Light enough to carry everywhere, small enough to fit in any pack. When you need it you will be happy. The bag design is many times better than the blanket. Dont waste your time with a blanket, get this bag.

This may be the smallest/lightest piece of gear that has the greatest potential to save your life in a not so uncommon emergency... getting stuck in the wilderness overnight without shelter. If this situation occurs in mild conditions, this bivvy will keep you from mild hypothermia. However, if you're backcountry mountaineering and SOL stuck in a surprise storm this little fella can mean the difference between surviving and not.
Also, I think it's superior to the emergency blanket because your body is sealed from the elements, instead of having to worry about gaps.

I have used a product similar to this while in Special Forces in the mountains of Afghanistan in the winter. It is an unforgiving envionment with the proper gear. Our tactical situation demmanded the we "go light." This means that you strip a strip a special bag off your about, 200lb pack, which contains only essentials (contents classified.) You blow the packs with C-4 and bugout. One item (unauthorized, but we all got them) in the bag is a thin, silverized on one side and OD Green on the other. You place the silver side towards the body and huddle together. Granted, it is no super sleeping bag, there were a few tears; but all of us lived until extraction. For those who critisize them try to think and remember, they are emergency devices, not your 1K fart sack.
