I was just getting ready to order the under armor briefs for everyday use and for training...I use the under armor boxer briefs for martial arts and they are great but I wear Sprawl shorts over them and the Sprawl are like nylon so theres no friction between the two fabrics,.. but I cant stand the feeling of wearing the longer style boxer briefs under normal pants, so I figure the briefs will be the ticket..Man I have waisetd so much $$ on underwear that doesn't fit its pathetic, even ones they call "athletic" are still built for people with no ass and skinny legs, I got a 36" waist and can't fit in size 42 normal underwear...so I gotta say under armor is the way to go...
