Trunks

Men's trunks with a 3 inch inseam and the patented Joey Pouch® built in

The shortest cut in the 2UNDR lineup, designed for shorts season, lighter layers, and anyone who likes a trim fit without sacrificing support.

The 3 inch inseam sits high on the thigh, which means no fabric bunching under athletic shorts, swim trunks, or warm-weather chinos. The Joey Pouch® keeps everything supported and separated even in the shorter cut, with breathable construction and a roll-resistant waistband that doesn't ride up when you sit, stand, or move.

Want a longer cut? Step up to our men's boxer briefs at 6 inches for everyday wear, or long leg boxer briefs at 9 inches for max coverage under athletic pants.

Pick your fabric. Sport Shift for laser-cut ventilation and a sport feel. Flow Shift for lightweight quick-dry performance. Swing Shift for soft modal comfort built for everyday wear. Every option uses premium fabric that resists shrinking, fading, and pilling. Gets softer with every wash.

Built for summer, the gym, the pool deck, and any day you reach for shorts. Available in solids and limited prints. Stack styles in our men's underwear multi-pack for the best per-pair price.
