Review (3/5): so the tightness is unnecessary. Definitely
This cap is a little too tight. I have a small to average size head and this was a little too tight. I am not planning on going swimming with this thing and do not need a water tight seal, so the tightness is unnecessary. Definitely, do not think it should be labeled or sold as "XL." I have medium length hair that is not thick and can see how this would not really work for really thick or long hair.
