The refillable Float compressed air cylinder is the power and driving force behind BCA's Float system. When the Float trigger is pulled, it activates the release of 3,000 psi (207 bar) of compressed air, inflating the airbag. Always make sure your cylinder is full and connected correctly before heading out. Can be purchased full or empty. Only compatible with Float 2.0 systems. Sold separately. — STAY AFLOAT. - Our original Float avalanche airbags were designed to be light, affordable, and easy to use. They have lived up to that since 2010, as the best-selling avalanche airbags in North America.
