These do everything you would want in a swimsuit.  They don't move around, they dry quickly, and they last.

I swim laps 4 to 5 days a week in a HEAVILY chlorinated public pool, and these suits still look and fit great after 5 months.  I've never experienced the problems stated by other reviewers.  Just be sure to rinse them well after each workout and then air dry.

I've worn quite a few suits over the years and these are hands down my favorite.
