Save yourself from wasting energy in an emergency whether you're paddling or competing in a triathlon with the Airbelt 2 Personal Flotation Device. It transforms quickly into a buoyant bubble if things go awry, and it's exactly what we want when we're wading out into calm, warm waters. The Airbelt 2 PFD's sleek design packs in 29 pounds of buoyancy should we take an unanticipated spill off our boat or board, and it quickly inflates by mouth or with the use of a CO2 cartridge.
