This ultra-compact and lightweight bivy offers versatile protection in any season. Like the E-Wing^™, it's factory compressed to the size of a soda can so you can easily carry it along as an emergency shelter—even on day trips. It’s also provides complementary, ultralight protection for your sleeping bag under a tarp, or a boost in warmth when pushing your bag’s temperature rating between seasons. A durable, coated floor and silnylon top fend off dew, frost, light precipitation and, once deployed, the stuff sack expands for easy packing.

• Reliable Protection: Coated and fully waterproof floor keeps you dry—even on wet ground—and slows heat loss.
• Ultralight and Compact: Weighs a mere 9 oz. (.25kg) and comes factory compressed in a soda can sized stuff sack.
• Versatile: For outdoor emergency use, planned fast and light trips, or inside a tent to add warmth.
