ARVA

Reactor 32L Flex Pro Airbag Backpack

What Our Gearhead® Experts Are Saying:

"This pack is my go-to for big backcountry days when I need durability and a top-tier airbag system. The REACTOR 2.0 is incredibly light for its protection level, and I love how the FLEX system lets me swap pack sizes on the same base unit. It’s rugged, well laid out, and gives me peace of mind in avalanche terrain."

We pack the Arva Reactor 32L Flex Pro Airbag Backpack for full-day tours when durability, comfort, and avalanche safety all matter. Its Cordura-reinforced panels stand up to tree branches, ski edges, and abrasive snow while the N330D Ripstop body keeps weight down without sacrificing toughness. At the core, the REACTOR 2.0 airbag system is the lightest on the market—just 650 grams—deploying twin 75-liter balloons for maximum surface area and redundancy in the event of an avalanche.

Built on Arva’s FLEX Technology, this pack allows us to swap between different capacity covers on the same base unit in seconds, making it a truly adaptable tool for the backcountry. The 3D-FIT adjustment system dials in our torso length, shoulder straps, and trigger handle position for a perfect fit, while dedicated snow-safety and valuables pockets keep gear organized. With ski and snowboard carry options, ice axe loops, and hydration compatibility, this pack handles technical objectives with confidence.
