We started BN3TH in Vancouver, BC, to radically change how men think about underwear. No one performs at their best when they’re adjusting. Or shifting. Or sweaty.Increased Comfort = Increased Performance We were the first to create underwear with a three-dimensional pouch, and our patented MyPakage Pouch Technology™ remains the key to our uniquely supportive fit. We engineer underwear and base layers that keep you comfortable for full days on the mountain, on the water, in the gym or in the office.
