Sleek, lightweight, and reliable, the Sopris Pro Avy Airbag is large enough to carry all your essentials during adventures in avalanche-prone mountain terrain. The included Alpride E1 deployment system operates via a supercapacitor, which—unlike traditional lithium-ion batteries—is temperature-resistant and travel-safe. With other snow-focused features, such as an integrated helmet port and ski/snowboard attachment points, you can move through the backcountry with complete confidence.
