About BN3TH

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. Over time, we evolved as a company to begin championing a full range of apparel for any and every consumer, endeavour, occasion, climate and style. We work hard to minimize the environmental impact of our business and contribute to causes that help preserve our planet.
