Just for reference, I am a 5 ft 8 and 135 lbs female. I found that the size small fits me the best! These pants are soft, stylish, and I love the rear and front zippered pockets. Only slight con would be that the pockets inner material is a bit weird feeling, but that just might be a me thing, so I still give them a 5 star review! I've been wearing and sleeping in them non-stop since I got them a few weeks ago. They also wash really great!
