These work well for my husband when he runs. They are smooth and light and fit as expected. He wishes they were a little longer, but that’s the case with just about every tee and tank for him, he just has a long torso I guess. I figured it was worth mentioning if you also run into the same problem. Don’t get me wrong- it’s not like they’re too short, they’re the length that the majority of tees and tanks are. This is a nice set and the price is reasonable, I would recommend it. I hope you find this review helpful
