A compact backpack with the optimal safety of Arva’s Reactor system

The Arva Airbag Reactor 18 Avalanche Backpack provides you a safety net for worst case scenarios, without weighing you down in the backcountry. The easy-to-use Reactor system provides you with a 150L airbag capacity, easily deployed in an avalanche to move you upwards and away from trouble. The R18 Avalanche Backpack is both light and compact, ideal for the freerider who likes to keep gear to a minimum without sacrificing safety.

The Arva Reactor system

Through fifteen years of development, the Reactor system features twin 75L bags that inflate reliably upon deployment. The airbags are shaped to increase chances of float in a slide, moving you closer to the surface. The system weighs in at 790 grams and can be moved to alternative Backpack sizes when required.
