I swim with a masters team at the YMCA twice a week.  I have only had the suit for about 3 weeks.  It's a lot more durable than the lycra suits, but not as comfortable.  It definitely seems to be a good suit for everyday workouts.  Time will tell.

We use these as our team suits and they seem to hold up better than any others we've tried.

This TYR jammer is a snug, comfortable, and nice jammer.
I have had it for almost a year, and after all this time, and swim workouts, it has not fallen apart or become transparent.
An excellent practice and conditioning suit.
No complaints.
