A video from FXR shows its F.A.S.T flotation assistance technology in action.
The description from the video states, “F.A.S.T. Float Assist Safety Technology offers buoyancy assistance when submerged in water. F.A.S.T. allows riders to stay afloat, while rapidly draining water and self-leveling to assist the escape. Feel confident knowing you are wearing life saving F.A.S.T.”
