Product information Power through your next goal! Our men's Powerskin Thunder wetsuit was conceived in an effort to understand the essence of what open water swimming beginners need from a wetsuit. We utilized our proven legacy and experience in the sport to provide novices with a clear-cut solution to their racing needs. The Powerskin Thunder technology combines all the essentials of a high-performing wetsuit: optimal flexibility, buoyancy, insulation and comfort. This men's wetsuit exclusively uses a Yamamoto limestone neoprene: the extreme flexibility of this quality material and the strategic thickness distribution of the neoprene translate to a wide range of motion and unrestricted feel that facilitates the swimmers' natural movements. The Thunder wetsuit also features a low-profile collar that prevents chafing, 100% waterproof double-blind stitched seams and an improved zipper closure for a secure seal. Be ready for your next race with this FINA, World Triathlon (ITU), Ironman, & USAT approved design.
