Survive Outdoors Longer (SOL) makes emergency shelters for the backcountry rescue market. The Escape Bivvy is their multi-use emergency sleeping bag: waterproof, breathable (unlike a standard mylar space blanket), and designed to reflect body heat back toward the occupant. At 8.5 oz and fitting in a jacket pocket, it's the most capable gram-for-gram shelter in existence.
A standard mylar space blanket traps heat but doesn't breathe — condensation buildup soaks clothing and negates the insulation benefit. The SOL Escape uses a breathable reflective material that reflects radiant heat outward while allowing moisture vapor to escape. The thermal performance improvement over standard mylar is significant.
The Escape Bivvy is designed for multiple uses (careful use required). Standard emergency blankets are single-use. For a kit item you hope never to use but might need five times, reusability matters.
