Polyester swim caps are very porous which means they will not keep water out. The benefit of a Polyester cap is that they are very lightweight and are ideal for swimmers with long hair to prevent it getting tangled in goggle straps or in their eyes. These caps are often used under another style of cap to stop the latex or silicone pulling the hair and keeping the hair in place.
