The Hair and Ear Guard by Sync Swimwear will extend any swim cap, which helps to keep your hair dry underneath of your cap. Ideal for long hair and added protection. Simply slip this specially made headband in place and pull it down over the hairline to help seal out the water when you swim. The hair guard can also help to provide additional water protection over your ears. Wear over your ears with ear plugs for even greater protection. Made from 100% silicone and comes in a variety of colors to match or blend with your swim cap.
