IF YOU NEED TO GO FROM ONE SIZE TO A LARGER SIZE, EXPECT THE SEAT OF THE BRIEFS TO FALL HALF WAY DOWN TO YOUR KNEES, THE MANUFACTURER THINKS JUST BECAUSE SOME ONE GOES FROM A LARGE TO AN XL THEY NEED 4 INCHES LONGER BRIEFS, THAT IS A JOKE, ALL A PERSON NEEDS IS A LITTLE MORE ROOM IN THE WAIST.  SOME ONE NEEDS TO WAKE UP AND WISE UP THAT A LARGER SIZED DOES NOT NEED TO BE LONGER.
