I am 5’8 180 lbs and M seems to fit ok, but the straps are too short. They almost bottomed out, no where near the Velcro. If I pull them up and put the two Velcro parts together, the pants will be too high and too tight. They should probably use buckles like my Volcom and DC bibs. Otherwise great pants and a keeper. If they change the straps I will buy again. This one is going back.
