Gear Guide 2012: Adventure Medical Kits Escape Bivvy Blanket

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

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
