Bivy Sack Reviews

Gear Guide 2012: Adventure Medical Kits Escape Bivvy Blanket

Using a waterproof and breathable fabric, the Escape Bivvy provides comfort and insulation.

[bivouac sack]

Most emergency blankets and survivalist bivies provide insulation but don’t breathe, making you damp. The Escape Bivvy solves that problem by using a proprietary waterproof/breathable fabric that lets moisture escape while reflecting body heat to boost warmth inside.

Our tester used it alone, without a sleeping bag or pad, on a 43°F night and felt instant heat. A drawstring hood closure further prevents heat loss, although it doesn’t cinch shut entirely, compromising the shelter’s weather protection in hard rain. A side zip running to the knee makes it handy for non-emergency uses like adventure racing. $50; 8 oz.; surviveoutdoorslonger.com
