Comments about Speedo Solid Silicone Cap:

I bought this for lap swimming to keep my long hair out of my face and to protect my color treated hair. Serves me well for over a year now.Difficult to put on at first until you master the technique. Itis a bit snug but it is suppose to be. I don't have a large head but do have a lot of hair and it all fits under the cap.
It is very thick and sturdy and have never torn it with my fingernails like some lycra caps.

I use this cap to protect my bald head while cleaning the bottom of my sailboat. It works for the job but is a little tight on my size 7 5/8 head.
