Zone 3 designed the Women’s Aspect wetsuit for open-water swimmers using breaststroke & front crawl techniques. By incorporating Aqua-X, Smoothskin, & high-stretch nylon panels, the Aspect gives the lateral leg movement required for breaststroke leg kicks. A combination of 1.5, 2, & 3mm thicknesses allows the legs to stay submerged, helping you maintain a natural swimming position.
