The Zone3 Aspect Thermal Wetsuit is ideal for those who like the open water, even during those colder months. Built with a Heat-Tech fleece lining designed to keep key muscles warm, this Breaststroke focussed design was constructed with Super Composite Skin, Smoothskin and high stretch nylon panels to allow a greater range of movement. The range of thicknesses throughout the suit ensures the legs stay submerged to maintain a natural breaststroke swimming position, while the Flatlock and glued seams allow extra stretch in key muscle groups.
