Ergonomically shaped DIN and YOKE screws, made with a bi-material Soft Grip surface, provide a better hold when installing or removing the first stage, even with cold hands. The new front cover opening channels allow water to flow sideways over the diaphragm, minimizing any disruptions in your diving experience. And with the overmolded exhaust cover made of elastomer with a soft touch effect, you can expect lasting durability and a comfortable feel.
