UltraSoft Trunks 3.6" OpenFly – Silver Series, White
Premium men's underwear designed for everyday comfort and performance. These short boxer trunks feature a mid-rise fit and 3.6" inseam: ideal for daily wear, travel, or light activity.

A large open internal pouch with angled horizontal fly offers easy access, ventilation, and pressure relief. The open-fly pocket-style design with a soft fabric curtain provides secure support and minimizes overheating.

Crafted from a soft cotton-elastane blend (95% cotton, 5% elastane), these trunks deliver breathable stretch and a gentle fit. The cooling technology reduces body temperature by up to 1.5°C, while the ergonomic construction enhances airflow and freedom of movement.

Details include clean-cut hems that stay in place, a wide gusset for mobility, and a soft 4 cm waistband that holds without pinching.
