These fit just fine - I’m 5’10, 170/175 and went with medium. They’re comfortable, they stay put, and the liner pocket works well. Compared to another brand (pinkbomb), these are less expensive but are missing two features. 1 - a small zipper pocket which is great for putting a house/car key in when out for a run. 2 - a pre-made hole for running a headphones cable through and into the phone. This isn’t too important since most of us have BT headphones nowadays.
Anyway, if these shorts had a little zipper pocket, I’d rate them 5 stars. Very nice choice though.
