2UNDR Swing Shift Trunk in Coastal Black delivers refined men’s modal trunk underwear with patented pouch engineering and streamlined 3" inseam fit.
Constructed from Lenzing Modal beechwood fibre, this mid-rise trunk provides a smooth, breathable foundation with natural stretch and lasting comfort. The Coastal Black pattern adds subtle depth and texture while maintaining the clean, technical identity of the Swing Shift line.
Engineered with the signature Joey Pouch™, the design separates and lifts for a precise, secure fit that reduces unwanted contact. The No-Drip-Tip™ hydrophobic lining actively draws moisture and body heat away from the skin to keep you cool and dry throughout the day.
- Patented Joey Pouch™ – lift, separation, and airflow optimisation
- No-Drip-Tip™ technology – moisture management within the pouch
- 3" inseam trunk – flatlock seam construction and 35mm roll-resistant waistband
