Built for racing, the LZR Racer® Element Openback Kneeskin creates a streamlined shape in the water. The knitted EnduroFlex fabric combines compression with freedom of movement, enabling you to feel fast, focused and comfortable off the blocks. Bonded inner liners create a clean, streamlined silhouette while the knitted fabric has a PFC-free water-repellent finish, which is better for the environment. The open back maximises freedom of movement and may be preferred by swimmers with arched backs. This product has been fully approved by FINA.
