Designed to withstand demanding and intensive use, the R40 PRO FLEX's accessories have been designed to adapt to all situations. Perfectly equipped to carry skis, a snowboard or an ice axe, you can also carry your skis diagonally or laterally (A-Frame) to limit the load shift and reduce your effort during the carrying phases. Its safety pocket on the front of the bag makes your shovel and probe accessible in a fraction of a second. Reinforced and optimized to resist moisture and abrasion, your ARVA REACTOR airbag equipped bag will never let you down. With reinforced foam and our 3D-FIT system, you will enjoy maximum comfort that fits all body shapes and sizes.

    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.
  • Inner storage pocket
    Designed to store and organize your small items inside your bag.
  • Daisy chain
    Daisy chains are extremely useful and versatile, allowing you to strap a wide variety of gear to your pack depending on the outing and your immediate need.
  • 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.
  • Quick and easy A-frame ski carry system
    Attach skis to your pack in just two clips. The A-frame ski carry system works especially well for wider skis and spreads the load more evenly.

    We recommend also using a strap to attach the ski tips and spread the tails apart.
  • Gear loops
    The waist belt is equipped with gear loops: two small loops on the left, and one large loop on the right.
  • 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.
