These are truly the best bike shorts I've ever ever worn to run in. These are the first shorts EVER (and I have tried pretty much all the big activewear brands) that don't ride up or roll down when I run. The material is also AMAZING!!! It is soooo thick and such good quality, but doesn't show sweat at all! Even with the lighter colours (I have these shorts in many colours haha, but also want many more). Seriously do yourself a favour, especially if you're a very active person, and buy these shorts.
