We gotta be upfront about something - these simply aren't our best product. According to our development head, the material didn't turn out the way we hoped, and after mass production we found that the metal onglets come off after a few washes if not before. But you know what? We've priced them accordingly and we think it's still a great pair of shorts at an amazing price. We don’t recommend these for training, but they are great to lounge around it, relax, and even sleep. We've made these out of our ultralight 100% polyester material. And as always, if you don't love them, we'll give you your money back.
