The Alproof equipped with Alpride E2 avalanche airbag system and the very latest supercapacitor technology deploys reliably, quickly and at high pressure, even in freezing cold temperatures. With multiple deployments possible, easy handling, and a quick-access avalanche equipment compartment, plus superior carry comfort and a snug fit with zero load wobble, the result is a controlled backcountry ride every time. A leg safety strap prevents the pack from being ripped off in an avalanche, while a helmet bag, gear straps and gear loops make this TÜV-inspected avalanche airbag backpack a serious mountaineering pack too.
