I got the small, long because I am 6'1 and skinny. They fit great and are extremely comfortable. I have worn them only 4 times so far but think they provide me with a great range of motion. My fiance will say that it doesn't take much range of motion to get off the couch but I disagree! Many times I am jumping over the couch and out the door. I think they look pretty sweet too but if your significant other is fashionable then they will ask you if you are wearing a parachute. Surprisingly cold winter so far in Alabama but can't wait until early spring to really test these bad boys out.
