Radically better underwear.
MyPakage Pouch Technology™ remains the key to the uniquely supportive fit of BN3TH underwear. They 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.

Pro Ionic
Go ahead, get sweaty. The PRO IONIC+™ Boxer Brief was made to move: BN3TH has elevated the breathable, moisture wicking wonder that is the Pro by adding IONIC+™ NO STINK Technology, a permanent silver anti-odor technology that kills stink before it starts by preventing the growth of odour-causing bacteria and won’t wash out. This 6.5 inch style keeps your sweat wicked, your form tight and your boys fresh.

Classics and Classics Trunks
These luxury Boxer Briefs feature an ultra-soft, breathable, lightweight Tencel™ Modal that is sustainably sourced, guaranteed to stay smooth and keep you comfortably supported at all times. MyPakage Pouch Technology™ lifts & separates your boys, eliminating the need to shift or adjust.
