In my misguided youth I only bought underwear that was on sale at discount stores.  From Haynes to Calvin Klein, I must have bought them all.

When I've bought cheap boxer briefs, they limited movement or the legs on them crept up during the day.  No matter boxers or jockeys, the front fly has often presented issues requiring adjustments during the day.  It's estimated that most men don't even bother trying to use the front fly to avoid navigation hassles.  I've had underwear shrink.

This Fruit of the Loom set of 3 briefs is different.  They're comfortable and didn't shrink too much.  They're so good that I got rid of all the others and bought more.  Now I only wear this one.
