This Water Polo Cap is ideal for adults and designed to provide comfort and functionality during swimming. This particular cap helps to keep the hair close to the head, preventing hair from falling into the water. Additionally, it reduces water resistance, making it easier for the swimmer to move through the water. Besides being made of a strong and flexible material, it also helps retain heat in the head during winter. While the cap does not keep the hair completely dry, it significantly limits contact with water, protecting the hair from the harmful effects of chlorinated water.
