From bootpacking out of bounds for fresh turns to venturing into the backcountry for a short sunrise tour, the ARVA ST26 Switch Reactor Airbag keeps us light, streamlined, and prepared. Equipped with two separate airbags, the Reactor system slashes complications in half for reliable performance. The adjustable back length, shoulder straps, and trigger handle height let us dial in a perfect fit, while the flexible shoulder straps and heat-moldable back panel hug our body throughout every turn and jump.
