My main reason for wearing boxer briefs is for comfort to keep my legs from rubbing together.  I initially bought these from Sams and loved them, but they stopped selling them.  Since then, I've tried Fruit of the Loom, Jockey and Hanes and none of them fit right.  They would either ride up, would rub in the wrong spots or were so loose, they felt like I was wearing boxers that didn't quite fit right.  I was forced to buy my britches off the web because I can't find them anywhere (thanks amazon)!  I threw all the others away and will only buy these now.  I also wear them while working out under my non-liner gym shorts and they are great for that too.  Try them!  You won't buy any others again!
