The Dakine RAS Removable Airbag increase the probability to be on top of an avalanche if you are caught and carried, aiming to minimize the burial depth, increase the chance of self-rescue, and cut down time needed to be discovered. Avalanche airbags can help to save someones life but are never a substitution for snowpack and avalanche education. The RAS Removable Airbag needs to be paired with a Removable Refillable Cylinder (sold seperately). Add the Dakine RAS Removable Airbag to any Dakine RAS style for a little extra reassurance when exploring the backcountry.
