Ready for adventure!

Inspired by our experience in the mountains and by our desire to provide you with high-performance gear, the ST30 REACTOR will quickly become your go-to avalanche airbag backpack for every ski trip or adventure on snow.

By streamlining the number of seams and panels, by using N400D PU2 waterproof and rugged ripstop fabric, and by equipping this pack with the lightest, most compact, highest performing dual avalanche airbag system available on the market, a minimalist approach has never proved so versatile or worked so well.

Comfortable on any sidecountry freeride or backcountry touring adventure, this pack will surprise you with its many virtues.

The multi-purpose strap system will prove more than capable of carrying all of your gear, whatever the situation. The YKK AquaGuard® zipper placed on the side of the pack provides quick access. Stow your shovel and probe in a separate, closed compartment, to forget they are there most of the time, and for split-second access in an emergency situation.

In terms of style, you can choose between a very elegant shade of blue or black for a more understated, refined look. Whatever your preference, the ST30 has character and will leave a lasting impression.

    Since efficiency is so important to us, we developed a system to open and close your backpack even quicker. Open the buckles and pull on the red loops to open the main compartment as wide as possible. To close, pull the drawcord and place the lid. The magnetic buckles will close the pack in an instant.
    Through our new, innovative LOW PROFILE technology, we decided to completely revamp the design our REACTOR avalanche airbag backpacks by integrating the airbag into the pack itself.

    The latest generation of packs designed with our LOW PROFILE technology means a more compact size, enhanced load distribution, and new features like the option of carrying skis in an A-Frame..
  • Multi-purpose straps
    A streamlined design no longer means having to compromise. Using our Daisy Chain system and multi-purpose straps, the backpack is capable of carrying skis, a snowboard, ice axes, as well as any other piece of gear that you consider essential.

    These straps can be used for compression on outings when your pack is not full, making the product even more streamlined and close-fitting.
  • N400D PU2 fabric
    Since our intent was to create a pack that will endure the worst weather conditions possible, we used N400D PU2 ripstop fabric for its waterproofness as well as its abrasion and tear resistance. All that along with a PFC-free coating.
  • Internal pocket for snow-safety gear
    Since we know how important it is to always carry your snow-safety gear with you, we built a specific compartment for your shovel and probe. Designed to keep your shovel and probe readily accessible whatever the load, you will forget they are in this completely separate and closed compartment most of the time, yet have split-second access in an emergency situation. When placed in their dedicated sleeves, your shovel and probe will not move an inch (or even a centimeter). This pack provides you with the means to be more organized and efficient.
  • 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.
