Question: what does ac mean???
Document: too small and too tight, can't wear it all. Maybe will give to some petite friend, if anyone needs it.
to avoid quizzical product in the pool this is the perfect item you need  in case of constan swimming100% recomended
this was exactly as advertised. it is worth what i paid for it.
this is okay; it doesn't stay on as well as my Keifer swim cap; I have to keep pulling it down after about ten laps which is annoying so I  only have it as spare in case I forget my usual cap; otherwise it is thick and seems it would last
this is my first time buying a swim cap now that summer is coming up soon. i've only tried it on while my hair was dry and didn't have much luck putting it on because it was so tight. I'm sure it goes on easier when your hair is wet. Everything else seemed fine
this is my first swim cap, recommended to me by a veteran swimmer friend. the cap does the job very well, and has lasted six months without a problem.
this is a very typical silicone swim cap for adults. the thicker material make it more comfortable to wear and i haven't experienced any issues with rips or tears
this does the job pretty well, I seemed to slip off my head a bit and I wonder if I didn't have it down far enough over my ears. it is soooo tight on the head though.
this could have designed better in the quality of the texture. It so sticky and hard for the kids without the help of other person to put them on.
this cap was too small for my head (and no, my head isnt abnormally large) and it does little to keep my hair dry. it also pinches my ears.
Answer: no
