Black Boxer Briefs
Men's black boxer briefs across the full 2UNDR lineup
Black is the most versatile color in the drawer. Wears under anything, hides everything, and never goes out of rotation. Pick your fit, fabric, and inseam.
Comfortable mens underwear in black for the bestselling everyday fit in soft modal. Sport Shift in black when you want laser-cut ventilation and a semi-compression feel for the gym, golf, or warm-weather travel. Day Shift in black for cotton-bamboo softness that gets better wash after wash. Flow Shift in black for lightweight quick-dry performance.
Every pair includes the patented Joey Pouch® for dual-pouch support, a roll-resistant waistband that stays flat under any waistline, and flatlock seams that disappear under your clothes. Premium fabric, built to resist shrinking, fading, and pilling. So your blacks stay black, not that washed-out grey that screams "time to throw these out."
Browse the full lineup of men's boxer briefs in every fit and inseam. Or stack a few styles in our men's underwear multi-pack for the best per-pair price.
Pick your inseam. 3 inch trunk for shorts season. 6 inch boxer brief for everyday wear. 9 inch long leg for more coverage and zero ride-up. Sized S to 4XL across the lineup, available in three-pack and six-pack bundles.
The black pair that earns its spot.
