Smartcap is a two-in-one headcover that is super easy to put on and comfortable to wear. It is made with an inner band that holds hair in place while pulling on the outer cap. Kiss those hair bands, clips and hassle goodbye! Ideal for fitness swimmers. The band is made of a technical elastic fabric that is durable, chlorine-resistant and easy on hair. The cap is made of waterproof silicone. Keep your cap performing longer by washing it in fresh water after use and air-drying it away from radiators or other heat sources.
