Mai Poetry Silicone Latex Swim Caps (2 pcs) Suitable for Long Hair Women Men Boys Girls All Ages and All Hair Lengths Summer Flexible and Resilient Comfortable Swimming Apparel

These are thicker. They stay put. They don't cover the ears....which I like. I have large head and they fit me just fine. Every swimmer knows the hair still gets wet, even using caps. The hair gets wet in these, too.

I bought several swim caps for my 8 year old daughter and had to return all them, except this one because it doesn't hurt her head.

These caps do not keep your hair from becoming wet. Too bad i didn't try them before the return window on this purchase was closed.
