This product was worn and reviewed by my 13 year old son. 5’5” 140lbs with an athletic and very muscular build. Size adult small fit very well. Pants are very lightweight/thin and ventilated well. Not good for cold weather, but great for gym, casual wear, or running. Tight secure fit around the ankles, enough to where it took him a little effort to put on. His calves and thighs are that of a strong man and still had room and mobility. The only reason for 4 instead of 5 star is that imo for the price the pants seem to be too lightweight/sturdy. Though he loves them, I can envision these tearing or becoming worn if used for anything other than casual wear for a period of time. $78 for a lined pant would have been more appropriate…these have the feel of something less expensive.
