The quality of the material used is great. The problem is that they have changed the pattern such that extra-large is too tight in the legs and rear. I have five sets of Noble Mount pajamas, but I have had to return the last three that I ordered. Only buy if you are getting an Amazon Prime purchase so that if they don't fit you the return is easier. By the way, my older Noble Mount pajamas still fit and I have lost weight so my size isn't the issue.
