Using your Zoggs Ultra Fit Silicone Swim Cap is easy. First, gently stretch the cap to fit over your head, making sure the ear mould with nodules sits correctly at the base of your ears. This will help keep the cap secure during your swim. When it comes to care, after each use, rinse the cap with fresh water to remove any chlorine or salt. Let it air - dry away from direct sunlight, as too much heat can damage the silicone. Avoid sharp objects that could tear the cap. And remember, styles are randomly selected at dispatch, so if you have a preference, make a note in your order. Each cap is sold separately, so if you need more, just place another order.
