BCA Float Systems are the lightest and most affordable avalanche airbags on the market. Systems use a 150 liter compressed air, single-chamber airbag and patented super-efficient Venturi system. Float airbags provide additional trauma protection to the head, neck and upper body. Positioning of airbag behind the head and away from the hips and arms allows for clear peripheral vision and ability to escape the slide. Compressed air cylinders are easily refilled.
