Bought these because I was tired of my old underwear just not fitting the way I liked in my dress pants.  The surf no show underwear go on and stay exactly where you put them, and I like that a lot.  For those other guys who are tired of adjusting themselves at the office or having issues with your under chaufing simply because it's moving around too much, these are the underwear for you.  I personally bought 6 pair of the black and purple (because I wear black dress pants to work).
