My husband generally wears a 34-35. He has a booty and a L did not fit him. The waist was good, the length was good but the butt section was way too tight and would have been uncomfortable to hike in. I ordered the XL for him and they fit perfectly. So if you have a butt, order one size larger. You will be thankful you did.
