Just when you think you have Mother Nature all figured out, she throws a total curveball at you. Even with proper avalanche safety training and good decision making, things can go wrong in an instant in the backcountry, so give yourself a last line of defense with the Mammut Ride On 30L Removable Airbag Backpack. If you get caught in an avalanche, simply pull on the deployment handle and the airbag fills up with 150 liters of air within roughly three seconds. This helps you stay on top or at least close to the surface of the slide so you're easier to locate and rescue. Plus, this pack has ample space for everything else you need in the backcountry, making it an essential addition to any backcountry gear cache. Once the airbag has been deployed, the padded waist belt, safety leg strap, and sternum strap will keep the pack securely attached to you, even in the turmoil of a slide. After deployment, deflate the bags and pack them back up according to instructions, and remember that the compressed air canister needs to be replaced. You can even remove the airbag system entirely if you want a lightweight in bounds pack, or swap it between all RAS packs to fine tune your carrying capacity. The Ride On 30L wouldn't be that useful if it wasn't a functional pack, too, so Mammut made sure it had all the features of a modern freeride pack, like ski and snowboard carry systems, a special pocket for your avy tools, and gear loops for ice axes and ski poles. You can stash your goggles in the padded pocket for safekeeping and toss a bladder in the hydration compatible sleeve so you don't have to gobble snow all day. All this weight is carried comfortable by the V frame aluminum suspension, thermo formed back panel, and removable waist belt. Please note that this system does not include the Refillable Compressed Air Cartridge, which is available separately MAM008Y. And please remember, this airbag system is NOT a guarantee that you will survive an avalanche get educated, get t...
