An avalanche is like a shark attack you can do all the research, take all the necessary precautions, and still be caught unawares when things go off the rails. Mammut's Pro RAS Removable Airbag System Backpack can help you stay on the surface of a slide when you kick one off unexpectedly, with a large quick deploying airbag that increases your likelihood of staying on top and boosts your visibility when the slide has come to a stop. The Pro RAS, which comes in 35L or 45L iterations, has plenty of room for all your gear, avy kit, food, and water. Access is super easy, with a fully zippered back panel and top U zipper, and your shovel and probe are easy to pull out of the purpose built front tool pocket. Mammut included a diagonal ski carrier that stows away when not in use, along with a vertical snowboard carrier, stowable helmet carrier, plus multiple attachments for two ice axes or trekking poles. A 6mm aluminum U frame suspension system efficiently supports and transfers the load to your hips to save your back and shoulders on those long hauls, and thermomolded back padding delivers killer comfort during day long tours. A removable padded hip belt lets you go streamlined with lighter loads and features its own pocket for small frequent use items like a compass, map, or inclinometer, and a sturdy safety leg loop helps keep the bag in position in the turmoil of an avalanche. Mammut built in a low profile sleeve for a hydration reservoir, tossed in a padded goggle pocket to keep your shades secure, and topped the Pro off with compression straps to cinch down your load for stable carrying. Please remember, this airbag system is NOT a guarantee that you will survive an avalanche get educated, get the right tools, travel with partners, and be smart out there.
