Even if they weighed thirty pounds, airbags would still be worth hauling around in the backcountry. Luckily, Arva's Reactor 25 Ultralight Airbag Backpack only weighs three pounds so you can still be light on your feet while you tour through the backcountry's avalanche terrain. Just because it's lighter doesn't mean Arva modified the airbag to be lighter--that just sounds scary--but rather, paired the Reactor with an ultralight backpack that still boasts plenty of features (ski carry, snowboard carry, hydration compatibility, avalanche gear sleeve) and a capacity suitable for half-day tours. The airbag itself features a gas canister deployment (cylinder sold separately) through dual air chambers around your neck, head, and sides for increased shock absorption and overall reliability. There's a chance an avalanche could pop an airbag, but this bag's dual chamber design can help you stay afloat if only one chamber pops. Arva made the safe-locking, retractable handle completely adjustable so you can place it right where you want.
