The key to increased speed gain from wetsuits is achieved through the added buoyancy they provide. Wetsuit buoyancy helps to lift the body into a more efficient angle in the water. On the After Burner, the hips and front thighs are built with 5mm thick panels, while the upper torso is built using 3mm thickness. To maximize a full kick, swimmers will appreciate the use of 3mm thickness in lower legs. Raised treads on the 2mm thick forearm sleeves add traction in the catch phase, and Fin Skin channels in the shins increase kick thrust. A GlideSkin exterior on this suit reduces drag and enhances durability while ankle zippers allow the suit to be removed quickly for speedy transitions.
