I’m 5’8”, 170lbs, 34” waist. I ordered a large but could have gotten away with a medium. Large fits comfortably, just baggier than I wanted. My thighs are about 23” and these have about 2” of slack even after 2 washes. Would order again, but I would say size down if you want them to be fitted.Great fabric. Nice thick waistband that’s doesn’t squeeze the your guts out. I could do without the logo on the back pocket but it’s small enough. I’ve gotten several compliments on them.
