We like how the Backcountry Access 2. 0 Float 22 Avalanche Airbag takes most of the negatives of an airbag and throws them out the window. Airbags are unquestionably good for backcountry skiing or snowboarding, but can be heavy, oversized and expensive. This bag solves those problems with a compact 22L design, padded harness system, and just enough features to keep us comfortable on our adventure. Plus, the 150L airbag doesn't hurt.
