Introducing the Carbon Core FX, the evolution of the Carbon Flex VX. Our Powerskin Carbon Core FX Jammers (FINA approved 2020) are engineered for a sensation of maximum strength. This men’s tech suit intensely compresses, oxygenating specific muscle groups called into action when swimming. It’s cut from Carbon Cage technology with horizontal and vertical bands locking onto the body. Parallel lines of dual taping on the back of the legs help maintain a horizontal, lifted position in the water, even when you’re tired. Feel powerful support and core stability on the inside with the internal taping system. Locked-in, lifted and ready to go.
