AirFlow Trunks 3.6" OpenFly – Silver Series, Yellow
Bright and performance-ready, these men’s boxer trunks in yellow offer ergonomic support and high breathability with a mid-rise fit and 3.6" inseam. Designed for active days, travel, and warm conditions.
A large anatomical pouch with a horizontal fly gives natural support, enhanced airflow, and fast access. Built-in support panels stabilize the anatomy and eliminate any pressure or discomfort.
The mesh gusset (92% polyester, 8% elastane) maximizes ventilation and moisture control, while the soft cotton-elastane body (95% cotton, 5% elastane) delivers all-day comfort and flexible fit. The lowered front reduces abdominal pressure and clean-cut leg hems stay in place without pinching. A soft 4 cm waistband ensures a firm and irritation-free hold.
Key Benefits:
Large anatomical pouch with horizontal fly – easy access and airflow
Mesh gusset – ventilated, cooling performance
