Mammut Removable Airbag System R.A.S.

Mammut Shop all Mammut
The Mammut Removable Airbag System (R.A.S.) is an avalanche safety device that may be installed in a compatible, R.A.S.-ready backpack. The system can be removed and installed in various packs of differing sizes for longer or shorter trips, or to suit lift-assisted purposes more closely. The system is shipped with an empty cartridge that must be filled before use.
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.
Airbag Volume - 150 liters
Airbag Inflation Time - Approximately 3 seconds
Operating Temperature - -30˚ C to +40˚ C
Compatible with all R.A.S.-ready backpacks
Warning - Wearing an airbag backpack is no guarantee of survival in an avalanche. Backcountry travelers are highly advised to educate themselves in snow stability assessment, route finding, and companion rescue and carry all of the conventional avalanche gear in addition to the airbag.
R.A.S. compatible backpack(s) must be purchased separately.
