Based in British Columbia, Canada, BN3TH (pronounced “beneath”) is on a mission to radically change how men think about underwear. No one performs at their best when they’re adjusting. Or shifting. Or sweaty. It stood to reason then that if their designs could offer increased comfort, then increased performance would follow. Utilizing the most advanced fabric technology and construction techniques available, this collection features underwear and base layers optimized to keep you comfortable, whether you're spending a day on the mountain, on the water, in the gym, or in the office.
