The Backbone Removable Airbag is an avalanche airbag backpack with an integrated PSA back protector. Thanks to its perfectly coordinated layered structure, the protector combines ultimate comfort with maximum safety. As well as with the back protector, the Protection Removable Airbag comes with a removable tailbone protector and a wide range of attachment options. In addition to a diagonal ski carrier and a vertical snowshoe and snowboard attachment, you can also attach a snowboard horizontally directly behind the back protector. This ensures great comfort and easy access to the main compartment despite the attached snowboard. With a packing volume of 18 liters, the Backbone is the ideal backpack for freeriding or on-trail descents.
