Customer Reviews

Comments: These are the worst exercise underwear I've ever tried on. The support was not that great and the mobility was awful. I guess they looked okay on, but that was the only plus.  I have designer briefs not intended for exercise that offer better support and mobility.  These are not suitable for running.  I will return these.
