I really like these underwear.  Looking at other reviews, I bought a large instead of medium that I usually wear (32 waist) and they fit perfectly.  They look great and feel good, although they are smaller than what I'm used to I will get used to them quickly.  Good for working out and/or daily wear.  I wish they had other colors besides white or black.  I will look at other CK underwear after having 2 pairs of these.
