Buy a size bigger
I wear a 30 in the waist, so I figured the small(30-32) would be good, not so much. The waist was more around a 28-30. And the legs were way to tight. A medium would probably be fine, but now their out of stock, just my luck. Just for your reference, I'm 5'6 and weigh 130, and a small is to small. Other than the size the pants they are very well made.
