Take your performance to a higher level with our newest racing design Powerskin ST 2.0. We created ST as a tech swimsuit for competition and training for swimmers of all levels. This upgraded women s open back one piece has a reinforced centre strap for better upper body support plus the shell fabric and new durable lining offer enhanced compression to targeted areas. Comfort and body stability are built in with ergonomic flatlock seams in a strategic pattern that lifts you underwater. More resilient and hydrodynamic than ever we love the edgy look of the contrasting seams. A FINAapproved design.
