FLOAT E2-25 - BCA's slimmed-down Float E2 avalanche airbag pack. All the same features as the Float E2-35, but 10 liters less volume, lower profile, and therefore no compression straps needed. — NONSTOP TRAVEL TO ALL DESTINATIONS - BCA's new Float E2 avalanche airbag packs use an Alpride E2 supercapacitor system to store energy that powers the compressor upon deployment. Supercapacitors store and release energy based on electromechanical properties rather than a chemical reaction like in rechargeable batteries. This makes supercapacitor performance much more reliable in cold temperatures. For the same reason, the energy stored in a supercapacitor releases faster when activated for deployment. — The new E2 engine is 40 percent smaller and 25 percent lighter than the existing Alpride E1 system, with a 162-liter airbag. Like the E1, the E2 is TSA-approved for hassle-free airline travel. While the E2 system makes it easy to travel by air, BCA's innovative Side Stash pocked and Back Stash zip make it easier to travel on snow—without stopping to hydrate,
