I purchased mens ultra light running shorts size L. I am a slim distance runner with a 34 inch waist (86cm) and thought L was best. These look great, they feel good on, and they are really lightweight, also I like the machined holes in the fabric. They are the correct fit around my glutes and groin but were a little loose around the waist; there is no adjustment in the waistband so I had to tie a knot in the elastic to fit me. The back zippered pocket is completely secure, I did not notice my house keys there at all, but the loop tie is stiff to open and not necessary; it is quite difficult to undo the zip while wearing the shorts and almost impossible to undo the security loop, I (almost) had to take the shorts off at my front door to get the key. The width of the bottom of the legs is narrow so the hem moves across my skin as I am running, with the result that I am getting a leg shave in a narrow horizontal band across the front of my thigh. Overall a mixed review.

extremely light

Light, comfortable and work really well with runderwear boxers.

A good, lightweight, running shorts without liner was what I was looking for. It's perferct. I also like the light grey colour. Could use some pockets more, but yeah I know, it's not a trailrunning short...

These are unlined. I get the intention is you're supposed to be wearing their underwear along with these. But for $65? An unlined short? Not worth it. I will say, they felt high quality and are very lightweight. Fit was all off though. They were strangely tight across my front, which made them look really weird and feel uncomfortable. Look elsewhere.
