Escape Bivvy

When a leisurely day hike turns into an epic survival situation, we're glad we packed the Escape Bivvy into our pack. The entire shelter weighs just 8.5 ounces, packs up small, and has an aluminum coating that reflects 70% of radiant body heat. And unlike most emergency shelters, the spun-bonded olefin material is comfortably breathable, so we won't end up feeling clammy and chilled to the bone.
