2UNDR
2UNDR Swing Shift Trunk in Horseplay delivers engineered men’s modal trunk underwear with elevated pouch support and bold graphic detailing.
Featuring a 3" inseam mid-rise cut, this trunk is crafted from Lenzing Modal beechwood fibre for a smooth, breathable feel and flexible structure. The Horseplay design draws inspiration from Year of the Horse iconography, adding confident graphic character to 2UNDR’s performance-oriented silhouette.
The patented Joey Pouch™ gently lifts and separates to create a contoured, friction-reducing fit. Finished with No-Drip-Tip™ hydrophobic lining, the pouch manages moisture and body heat efficiently, supporting dryness and comfort during daily wear or active use.
