Bought these along with a couple other similar from other brands in order to find stealthily comfortable pants for a (moderately) professional setting in a physical therapy clinic.While the waistband stretches, the pants material itself has no stretch whatsoever, which was very disappointing.I ordered a large. I'm a 6' tall 30w/32l or 32w/32l guy. Waist was very comfortable, but the legs were way too short, coming up onto my shins when I bent my knees. I think this may be a fashion choice but it wasn't good for me. Also while I do work out I don't have thunder thighs like the model in the picture, but they were still pretty restrictive when trying to move around.
