Emergency Survival Bivvy Bag — Lightweight Mylar Sleeping Bag, Reflects 90% Body Heat, Waterproof
$14.41
An emergency mylar bivvy bag belongs in every day pack, vehicle emergency kit, and hunting pack because it weighs next to nothing and takes up almost no space — but it's the difference between a bad night in the backcountry and a fatal one if a situation turns serious. The reflective mylar material bounces roughly 90% of body heat back to you, which is how a bag that packs smaller than a paperback book can meaningfully protect against hypothermia in 30°F temperatures.
- Reflects approximately 90% of body heat — works in hypothermia-risk conditions
- Weighs under 4 oz — no meaningful weight penalty for always carrying one
- Packs down smaller than a fist — fits in a hip-belt pocket or bottom of a day pack
- Waterproof mylar outer sheds rain and wind for additional protection
- Reusable construction — can be folded back for re-use on a second outing
