The lightweight material used in the Speedo Fastskin LZR Pure Valor Openback Kneeskin one-piece swimsuit gives you unreached levels of freedom in the water. It’s constructed to provide all four of your limbs power to make every movement in the water count, alongside light compression within the main body of the fabric that keeps your core moving through fatigue. Hydrodynamics are optimised to the full thanks to flatlock seams that are comfortable too, while the refined neck and arm openings add durability at the same time.
