This sleeveless triathlon wetsuit provides superior buoyancy throughout as well as flexibility in the upper back, shoulder and neck areas. It has all the features, functionality and efficiency of the Endorphin Full suit without the sleeves. This suit is simply the best in value when it comes to wetsuits. Endorphin utilizes the maximum allowable five mm neoprene on front panel for incredible buoyancy. SuperFlex and HiFlex rubber on the shoulder and arm panels boast an unsurpassed 680 percent flexibility for surprising comfort. Silicone treated neoprene makes the suit non-porous, producing an effect of low friction for maximum glide. The suit’s lining absorbs far less water than many others on the market, keeping it light and allowing it to peel off easily in transition.
