I swim almost every day. The PBT fabric holds up much better than lycra. This is a great practice suit.

After my other Speedo jammer wore out, I wanted another one.  I like Speedo, so when I saw this one had extra chlorine resistance, I bought it.  I haven't had it long enough to know whether it will last longer, however, it fits more snug than the other type I had. The material feels tad bit heavier duty, but it doesn't feel any different when swimming.  Good practice suit.
