When kitting up for a sunrise skin we organize our gear in the Free 22L Removable Airbag 3. 0. This pack gives everything a place with special compartments and attachment points for our avy gear radio skis and helmet and comes equipped with Mammut's ultralight compact Airbag System 3. 0 that deploys in full in just 3 seconds. The running-vest-inspired harness system hugs our back for a fit that won't disrupt our flow while the thermoformed back panel boosts comfort and sheds spray.
