Adventure Medical SOL Escape Lite Bivvy

All that separates you from the elements is 8. 5 ounces of waterproof breathable fabric, and that's all you need when you're bundled up inside the SOL Escape Lite Bivy. Unlike other plastic bag bivys, the Escape Lite features material that reflects heat but also allows sweaty moisture to escape from the inside out, so you stay warm, dry, and free from the freezing effect of your own moisture. Cold air has a tendency to creep in around the hood and zipper of most bivys, but the Escape Lite features a drawstring closure around the hood and a quarter length zipper that leaves less opportunity for heat loss. With a tiny pack size, massive warmth, and the ability to control moisture, the Escape Lite can serve as a reliable emergency shelter or a sleeping solution for skiers, backpackers, and fastpackers who want the lightest possible gear.
