I'm a very keen runner and I'm always buying new gear, but I also have drawers full of running gear that isn't quite right. Tops that ride up, tights that chafe or aren't flattering. A myriad of irritants that wouldn't bother you with your normal clothes but when you're running, particularly if you run anything over 10k, will really start to grate and annoy. I can honestly say that these are perfect. They keep you warm without getting too hot. They are a compression garment, but aren't so tight that you struggle to get them on. The waist stays where it should and doesn't roll down. They don't rub or chafe... Not too expensive. A great buy in my opinion.
