[Ear Protection] Our swimming cap is made of waterproof silicone material, providing extra space for the ears and a comfortable fit while protecting your hair and ears from chlorine and pool bacteria in the water. [3D Ergonomic Design] The ergonomic 3D styling helps create a secure fit. Strategic cushioning at the ear contact points prevents pressure build-up, and the design of the material will not entangle or pull hair. The advanced thicker curved edge design fits better and keeps the cap in place during long swimming sessions.

To put on, reach inside the cap with both hands, bend the fingers slightly, spread them with appropriate strength, and then place it on the head.
