I read a number of other reviews before ordering these, and I'm glad I paid heed to the notice about ordering them a size larger.  I immediately washed and dried them a few times upon arrival.  I take a medium and ordered large.  After the wash/dry routine, they fit nicely, so be advised that you will probably do better ordering a size up from what the instructions state.  They appear well constructed and they are defintely good material.  The last sets I got like these from FTL wore like iron (although not at all uncomfortable) and I'll be very pleased (and very suprised) if these wear as well over the years.
