“Strong like a bull” is a rousing compliment – unless they’re talking about how a fellow smells. That’s when hardworking men gird their loins with the stink-vanquishing, sag-defeating power of Funk No! Copper Boxer Briefs. Unlike standard skivvies, their amazing breathable poly/spandex mesh fabric contains Cupron® copper embedded fibers that kill odor-causing bacteria – preventing foul and funky smells at the source. And the anti-odor action won’t rub off or wash out, so it’ll staunchly fight stink for the life of your undies. Better yet, we’ve added Duluth’s exclusive Bullpen® pouch that holds your man-atomy comfortably in place. Get a pair and charge through your day free of uncomfortable swing, pinch and stink.
