I have to say this is the best men's brief I have ever worn.  I have a 35/36 inch waist and I got a size 7 (the size 8 was slightly too big).  They are ultra stretchy, super light weight and ultra smooth and silky.  The stretch frames the mens anatomy perfectly and offers comfortable support.  You don't even know that you have them on! I got black as well as white and they are basicly exactly the same as the old Jockey Men's Tactel bikini brief that they discontinued for unknown reasons.

These look identical to mens underwear except they are not bulky.  Once you try them once you will have a different opintion of all your current bulky, thick and unfun briefs.  My wife really likes these on me as much as I do.
