An injured person lying on snow loses heat to the ground faster than to the air, and that's what kills them before help arrives. The Degree Dam is a single-use air mattress that puts insulation between your patient and the snowpack, packed small enough that carrying it costs you nothing. It doubles as splinting material when you need it.
