I play roller derby with Slaughterhouse Derby Girls in Greeley, Colorado. After 3 hours of practice we go home super sweaty. Most of the time when you put your pads back on 2 days later some of them are still wet and smelly (we practice hard and play harder!). It's a full contact sport so we wear elbow, wrist and knee pads... that's a lot of sweaty surfaces.
I can wash my pads in WIN and they smell so fresh and wonderful. Then I'm every ones favorite player! ;)
