If you are borderline on size, and you don’t want them even tighter, better size-up when you buy. I’m 5’-10”, 190 lbs., and should’ve gone with XL.
I wear a size 32, got a medium. Fits a little loose, but the draw string holds them up. I really like the sweat pants.
I wear a 31" inch waist for pants and i got a medium. they fit a little big but i don't mind because the draw strings hold them on nice and tight!
