Very comfortable swim short for swimming laps. However, the black color faded and after about 4 months I had a pair of "gold" swim shorts. Now, another 8 months later, the material got so thin that it tore while I was swimming laps. Good shorts, but not very durable if you spend 6 hours a week in the pool.
