I've been wearing cheap cotton boxers for most of my life when I discovered real underwear.  There are two things that are critical for comfort clothing:  underwear and socks.  These things are great.  They're a little looser than Underarmor boxerjocks but still snug enough.

Just for the hell of it I tried getting a fresh pair wet to see how fast they would dry.  If you're in a humid environment it will take a while (6+ hours) for these things to dry completely.  Still pretty good.
