The Float 32s 150-liter airbag not only creates buoyancy and decreases your burial depth but also protects your head and neck from trauma in an avalanche. BCAs next generation Float 2.0 cylinder is nearly 30% smaller and 15% lighter than our Float 1.0 engine. All the Float 2.0 system elements sit entirely separate behind a zippered covering, freeing up valuable space in the main compartment for gear, first-aid kit, and supplies.
