I have to agree with Packin and Dipping. Undergear, or I.M. have a line of contour briefs that held up, and held me up quite well. I was first introduced to their line way back in 1976 before they were well known. It was a big relief to find an outfit that recognized a guy's got somethin' down there larger than a wish. The contour line last quite a long time (don't wear out or loose elastic). With proper care I can get a 2-3 years out of them. The best are the mesh contour Packin refers to. Airy, and don't shrink up as much after the wash as the solid jersey versions do. The best thing is that the pouch has so much give that if you are feeling a bit "fluffed" when putting them on, just run your fist down into the pouch and stretch it out. It does not seem to harm them and it is such a relief to have the room. I use the BA083 model and order just a few each year and rotate the old stuff out of service. They are great!
