The Float 42 Airbag Backpack is the largest of Backcountry Access' avalanche airbag line, designed to give for longer missions in the backcountry. Despite the bigger overall size, the included Float 2. 0 airbag system is 15% lighter than the previous model and about 30% smaller, meaning you can fit more gear in the pack, and features an ergonomic trigger mount so you can feel confident deploying the airbag in an emergency, no matter if you're left or right-handed.
