Durable and Functional: Made of high-quality silicone for maximum stretch and durability. Our swim caps are toxin-free, latex-free, and easy to put on and take off without snagging or catching long hair. Great fit that accommodates all head sizes and protects swimmers from chlorine. Waterproof: With our innovative technology, the silicone swim caps work very well to reduce water penetration and keep hair dry. They protect your hair (especially colored hair) from heat loss, sun rays, chlorine, or salt water. Stability: The swim cap is very easy to put on, and thanks to the non-slip interior, it will stay in place while swimming. You can enjoy your swim without worrying about the cap slipping while swimming. Comfortable to Wear: Premium silicone material offers extreme stretch and is suitable for both short and long hair. 3D ergonomic design fits the curve of the head, and the soft silicone makes it easy to put on, so children can enjoy swimming time.
