“I already had a pair of Army color in S. I decided to try an M. Super comfy to laze around in - just the elastic on them could be a big tighter as they do slip down if you have items in the pockets.
They are just a slightly looser version of the S. I’m a size 32 and after wearing both the S and the M I’d recommend the S as they are less baggy around free crouch and leg. But if you like a looser fit.. got for the M. Great product - do yourself a favor.”
