DURABLE + ULTRALIGHT + COMPACT – Our ultra-compact storage balances durability and lightweight at just 12 oz per set (2.5 oz per blanket). Stash them anywhere or carry enough for your whole group in the included zipper pack with carabiner.

PERFECT FOR HIKING, RUNNING, & FIRST AID KITS – Our NASA-designed mylar blankets are waterproof and reflect up to 90% of body heat, essential for survival in cold, wet, or hot weather conditions. Ideal for camping, trail running, marathon events, emergency go-bags, tactical gear, disaster preparedness, and car first aid kits.
