Finally, trail running shorts without built-in briefs!!! Lightweight and incredibly breathable, you feel like you're wearing nothing at all. The stretch is fantastic, I'm completely satisfied. I'm 1.70m tall and weigh 65kg, and the size is perfect... These will be my shorts for the Diagonale des Fous. Thanks Cimalp!

Fits great, ultra-light, it's perfect. The pocket is optional, maybe just for a car key, not a phone, as it's a bit snug and if you put something too heavy in it, the shorts slip down because the waistband isn't tight enough. But that's not what you ask from this short anyway—it's great for light outings.
