Note: The ONE person bivy is factory backordered until late January 2013. We have secured a few TWO person bivys and are shipping those instead during this period. They are slightly larger and heavier to accomodate two persons, but are otherwise the same product.
Possibly the worlds lightest sleeping bag, that could even save your life !
Adventure Medical Kits - Heat Sheets Emergency Bivy Pocket Size Sleeping Bag. The SOL (Survive Outdoors Longer) bivvy is made from advanced space blanket material. The AMK Heatsheets material represents a better, quieter, more durable reflective material than traditional mylar polyester space blanket products. Heatsheets polyethylene material is less subject to catastrophic rips and tears that would render a traditional mylar blanket useless.

Caring for your Heatsheets: The material is a stretchable, pliable material that gives instead of rips. You might see thin stretch marks in your bivvy after use or upon removing from the ultralight stuff sack. This is normal and will not affect the performance of your bivvy. If you do puncture a hole in your bivy, a piece of duct tape works well as a patch.
Usage Notes: A heat reflective bivy can function by itself as a shelter from cold wind and rain. However, you can still lose critical heat through conduction (the transfer of heat to colder surfaces around you). It is important to thickly pad the area underneath you with as much dry debris (leaves, balled up newsprint, pine duff) as possible to add insulation between you and the cold ground. Find a safe spot for your shelter that is free from risk of falling trees, branches, rocks, flash flooding, or other natural hazards.
Open the top as necessary to regulate heat to a comfortable level. Ocassionally open to exchange moist air for dry air, if you deem in necessary. The biggest source of moisture build up comes from respiration so it is best if you can breath outside of the bag (as pictured)
