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.

BN3TH sounds like the proper spelling; 'beneath' or bee-neath, |bəˈnēTH|. The meaning behind BN3TH ties in with our headline: BN3TH the Surface.  On a literal level you have what's BN3TH the Surface of your clothing, our first-to-skin products, and on a figurative level, what's BN3TH the Surface of you. BN3TH celebrates the duality in everyday people's lives, empowering them to express their true selves and showcasing the surprise and delight in each and every individual.  

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.
