A Little About Us

At BN3TH, we create engineered apparel focusing on men's underwear for all to feel confident in. We prioritize providing uncompromising support in the staple pieces that have a noticeable physical and mental impact on your everyday life.

We set out to transform the way men think and talk about underwear with our patented MyPakage Technology™ that eliminates the need for any shifting and adjusting thanks to a 3-dimensional internal pouch.

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.

Our inspiration begins in our backyard - the mountains, the ocean, the people, in beautiful British Columbia, Canada, but extends far beyond into the amazing world we live in.
