Introducing the Carbon Core FX, the evolution of the Carbon Flex VX. Our Powerskin Carbon Core FX open-back suit (FINA approved 2020) for women takes compression to a new level. This racing swimsuit is cut from Carbon Cage technology that works horizontally and vertically for long-lasting muscle compression and a locked-in feel. At the back twin-taping along the legs has a lifting effect on the body, helping it to stay high and horizontal in the water. The internal taping and lining intensify support and core stability. To add flexibility, we designed the lining with a slim opening under the chest.
