You thought you'd done everything right, checked the avy report, analyzed your snowpit data, done a ski cut. Three turns in, though, the snowpack fractures and starts to move with you in it . . . Instead of trying to outrun the slide or just hanging on and praying, you've got the Mammut Ride Airbag R.A.S. 30L Airbag Backpack on. A quick pull on the release handle fills the 150 liter bag within 3 seconds, tilting the odds of survival in your favor by floating you toward the surface of the slide. The design of the Mammut airbag system also helps cushion and protect your head and neck from impact. The Mammut Removable Airbag System (R.A.S.) uses a refillable air cylinder (comes empty) and can be removed for days when you think the avy danger is negligible or you need more space. Expensive? The first time it saves your life, it'll be worth it.

Airbag Functionality The effectiveness of the airbag is based on the "Principle of Inverse Segregation." In an avalanche, smaller moving particles gravitate toward the bottom of the slide while larger ones rise to the surface. The inflated airbag allows the wearer to become one of the larger particles. When the release handle is pulled, the airbag inflates within 3 seconds, and the shape of the bag also protects the wearer's head and neck from impact.
Mammut R.A.S. (Removable Airbag System) The user can install or remove the airbag system as required, moving it between compatible R.A.S. system packs. The cartridge is shipped empty and can be filled at most dive shops or paintball shops in the US and Canada that offer 207 bar/3000 psi dry air and have a standard paintball fitting.
Snowpulse Inflation System 2.0 The new System 2.0 is only compatible with newer Snowpulse R.A.S. units and is NOT compatible with older Snowpulse LifeBag packs.
