These are very soft, very light feeling.  They could use some more elastic at the bottom of each leg, but they are otherwise well-made.  I use them especially in the summer, as they seem cooler, especially when hiking.  I have not noticed any shrinkage after multiple washings.
The only other criticism, which may also be to some an advantage, is the lack of any label or light lettering on the inside to denote the back of the underwear; accordingly, I have to look for the front opening every time I put them on, which is a very minor annoyance.
