What level of buoyancy?
The Offshore Vest, Yoke and Slim Line Yoke are fitted with a 38gram CO2 cylinder. This generates in excess of 180 newtons of buoyancy more than is required for a PFD Type 1. All other styles are fitted with a 25gram CO2 cylinder and produces 130 newtons of buoyancy or approximately 50% more than is required for a PFD Type 1.
