Designed for high-performance mountain riding, the Float E2 MtnPro Vest offers full protection to the chest, ribs, and back – and now includes our Float E2 airbag system.
Our new Float E2 MTNPRO airbag vest uses an Alpride supercapacitor to store energy that powers the compressor upon deployment. Supercapacitors store and release energy based on magnetic energy rather than chemical reaction: This means their performance is much more reliable in cold temperatures. For the same reason, the energy stored in a supercapacitor releases faster when it’s activated for deployment.
See the “Battery and Charging” tab on this page for more details on how the supercapacitor works and charges.
The E2 Float MTNPRO Vest is our dedicated sled-specific airbag vest for mountain snowmobiling. Gearing up is easy with this all-in-one, lightweight breathable protective vest featuring built-in integration for a Tracker avalanche transceiver and BC Link radio. Other features include integrated low profile pack to carry avalanche gear and a few other essentials. Full front, side and back protection with 1mm of hard shell ABS sandwiched between two layers of PE foam. Oval “ergo” trigger is less likely to snag on trees than round or T-shaped handles.

Preventing or minimizing burial depth is the key to reducing avalanche fatalities. That’s because the majority of time in an avalanche rescue is spent on excavating the victim. An airbag is designed to keep you at or near the surface, minimizing excavation time.
How do Float airbags reduce burial depth?
- Inverse segregation, more commonly referred to as the ‘Brazil nut effect’ is the science behind why airbags work. The turbulent movement sorts different shaped objects by size (similar to the way large Brazil nuts will rise to the top when a bowl of mixed nuts is shaken). Smaller objects are more likely to fall into the voids created by the turbulence, while larger objects move to the top. In addition to increasing your overall buoyancy, the Float avalanche airbags are designed to make a backcountry user ‘bigger’ than the surrounding pieces of debris in an avalanche. The Floats use compressed air in the cylinder to fill the bag and make the user’s volume larger, reducing or eliminating burial depth and increasing your chances of survival.
