This cap, while it does the job it is intended for, turned out to be a poor investment on my part. This is my first silicone cap, and will probably be my last. While the shape and design of this cap provides one with an awesome glide like none other, it was quite uncomfortable. Maybe it just takes some getting used to. The first few times I used it, I found myself ripping it off after a half an hour of use because it was just too tight. I will admit that I have a fairly large head, but you would think a large-sized cap would accommodate this. I always value comfort over looks, and while this cap may work effectively and look cool and sleek, it is definitely not very comfortable.

this cap was too small and did not meet my needs and was returned.

I had read the comments about this product before I ordered so I am very pleased that I got the right size, L-size. it is perfect fit for my long hair. The material is good. I love your website store and definetly I will come back in the future because you care for your customers.

I bought this size large cap to fit my big head (24 inches, hat size 7 5/8), but I couldn't even begin to get this cap on. The material is so thick, it isn't very stretchy. It appears to be designed for people with lots of hair rather than a big head.

This is THE professional competition cap. Perfect fitting, there are not wrinkles on it while wearing it.
It is true that the medium size is too small for an older child or a girl with longer hair.

This cap is great!  I always hate caps because it's like wearing a rubber band around your head, but this one actually gets comfortable.  It's also a mix between latex and silicone, so it's fast, but still comfortable.  This is the best cap on the market, period.  When ordering at swimoutlet be careful though because each size cap is a different product.  I bought thr wrong size the first time, but they were good about exchanging it.
