I ordered a Lrg.  I am 6 foot 218 and have a 38 inch waist.  Theses fit perfect right out of the bag.  Not tight but not lose.  Very soft but not thick.  Now I have not washed them yet but plan on doing that in cold and just hang drying.  100 cotton handle with care  UPDATE  washed several times in cold and just hung to air dry and the still fit the same way they did out of the package
