2UNDR
2UNDR Swing Shift Trunk in Black/Grey delivers premium men’s modal trunk underwear with patented pouch support and moisture-control performance.
Designed in a modern mid-rise with a shorter 3" inseam, this trunk silhouette offers a streamlined, athletic profile ideal for everyday wear and active movement. Crafted from ultra-soft Lenzing Modal beechwood fibre, the fabric feels smooth against the skin while maintaining breathable stretch and structure. The black body with grey contrast stitching reinforces the clean, technical aesthetic that defines 2UNDR.
The patented Joey Pouch™ separates and gently lifts for a precise, contoured fit that reduces skin-on-skin contact and improves internal airflow. Lined with No-Drip-Tip™ hydrophobic fabric, the pouch actively draws moisture and body heat away to keep you cool, dry, and comfortable throughout the day.
