Good fit, rear pocket just about big enough for mobile and keys etc, although the mesh is a little bit big so I put my stuff in a plastic food bag as I'm paranoid about my key working its way out! Cool enough for running in warm weather. Some additional pockets would be nice as in some of the trail running bottoms available at Decathlon.
The new sizes has a medium as a UK size 14. They were tight particularly on the legs but also snug on the waist. The biggest negative was that there is a seem right across the back of the knees which is the join for the mesh section - this was uncomfortable and irritating so returning to store. I'm quire short, so it may not be as much as an issue for someone taller.
