The Exo suit is also available with increased single-lined material, the ExoSkin variant is designed for colder water applications where warmth and reduced wind-chill is paramount.  Carefully considered material selection means this hybrid suit does not sacrifice flexibility by maintaining double-lined superstretch material in the arms and legs.
ExoSkin is available in two styles: a winter 5/3 fullsuit and a warmer weather 4/3 short sleeve/long leg.
