These thermals are super comfortable.  There is a nice soft band at the bottom so they don't pull up around your calves, which is something that really annoys me. They are soft right out of the bag with no breaking-in period.  And best of all, there is no tag because the info is printed on.  I definitely recommend these thermal pants.  I am 5'4" and weigh 111 pounds and ordered a size medium.  I bought these to sleep in and they fit perfect for that.
