Ear protection: One of the main functions of the silicone ear protection swimming cap is to protect the swimmer's ears from the direct impact of the current. During swimming, water and waves may enter the ears, causing discomfort or infection. The silicone swimming cap closely fits the ear, effectively preventing water from entering, and reducing the risk of ear damage or inflammation.

Reduce resistance: the material of silicone swimming cap is soft and smooth, which can reduce the friction resistance between head and water when swimming. This helps swimmers to cross the water more smoothly and improve their swimming speed.
