Part of the exclusive arena Diamonds collection dedicated to the resilience of us all, that like diamonds we shine brighter when we are together, the arena Diamonds Women's Open Back Powerskin Carbon Core FX is an innovative tech suit for racing in a limited-edition print. Engineered for an enhanced sense of power, this women's kneeskin is cut from Carbon Cage fabric with horizontal and vertical bands locking onto the body for intense compression. New twin taping on the back of the legs helps maintain a horizontal, lifted position in the water, even when tired. The Carbon Band lining increases core stability for less drag and has an opening under the chest for better flexibility. An open back rounds off this tech suit for a close to the water feel. FINA approved.
