    CORDUA is a synthetic fabric with 3 times the abrasion resistance of other typical polyamide fabrics. While durable and incredibly robust, it remains relatively thin and lightweight.

    140Dx210D CORDURA polyamide ripstop HR is a thin fabric with a highly-resistant coating that can withstand the toughest conditions.
  • Dedicated snow-safety equipment pocket
    Since we know just how vital it is to be quick and efficient in rescue situations, we placed a dedicated pocket on the front of the pack for quick access to your shovel and probe.
  • Diagonal ski carry system
    Carrying your skis diagonally keeps them from interfering with airbag deployment in the event of an avalanche.

    Reversible, our system allows you to choose the diagonal direction in which you would like to carry your skis.
  • Gear loops
    The waist belt is equipped with gear loops: two small loops on the left, and one large loop on the right.
  • Removable waist belt pocket
    We designed the right pocket to be removable to provide professionals with the option of gaining more room on the waist belt to attach specific tools and accessories.
  • 3D-FIT
    Our 3D-FIT system allows you to quickly adjust your pack to your fit preferences and body size for maximum comfort. Select S, M, or L in just one pull to instantly adjust back height, shoulder strap length, and the position of the REACTOR trigger handle for the perfect fit.

Flex Technology
We developed Flex technology to allow you to change the carrying capacity of your Arva Reactor avalanche airbag backpack in just a few seconds based on need. This system include the Flex frame and the Flex cover. Our Flex technology does not require any additional zippers, which means no additional weight relative to a traditional reactor backpack.
