The BCA Float E2 35 Airbag Pack is a tech fueled upgrade to the legendary Float 35 airbag pack. The all-new E2 engine is powered by a supercapacitor, which despite sounding like something Tony Stark uses to power his super suit, is actually a real thing. A supercapacitor basically is a really awesome battery. It performs better in cold temps, releases energy faster, and is much lighter and smaller than traditional rechargeable batteries. All of which, of course is perfect for something you need to lug uphill in the cold with the hopes of never using, while requiring perfect, instantaneous response when you need it. Other than the new supercapacitor, the Float E2 35 remains a perfectly kitted backcountry pack, full of all the features you need for any tour in avalanche terrain.
