This product is a quality product made with good material but it is not sized correctly.
The relative length of the pants for the size is way too long.  Also the hips, thigh, and butt area is way too tight.  The sizing is equivalent to what you would find in a Men's "tall" or "slim" aizes.  Just because you wear extra large does not mean you are 6' 5" tall and 175 lbs.  I have purchased much sleepwear in my life so trust my basis of comparison.  If you are on the tall/slim side then these will do you fine but you still may have to order a size larger than your true size to avoid extra tightness.  I would not reccommend this line for husky men of average height.
