My second response, after looking closely, was "wow - so that's how to put a swim cap on the easy way". I know you are looking for a swim cap to keep your hair dry, but you should be aware that the swim cap’s primary function is to keep your hair secure from harmful chemicals used for making the swimming pool safe. The Soul cap is designed with great care and offers you the flexibility to seal your head and keep you safe from the swimming pool’s harmful chemicals. The Dsane swim cap’s primary function is to keep your hair safe and tyr solid keep them dry throughout the swimming session. In this case, you will have to wear two swim caps together (a latex swim cap first and silicone swim caps on top of it, but if you have a latex allergy, then you can also wear two silicone swim caps together.) to keep your hair protected and dry.
