I had an Amanzi 'stained glass' type swim cap. It was pretty, unusual, tough, stretchy, comfortable, and lasted for years. I never had to tug at it during swimming to keep it from feeling like it was coming off. I got this new one after a lot of work to find it. I have had to pull it down at the back of my head to keep it from coming off. I wonder though, they say the silicone is different from usual in that it so stretchy. I am hoping after using it a while it will stay on. The last time or two I used it I didn't have to pull it down, it was better. I am hopeful.
