FlexFit Trunks 3.2" OpenFly – Silver Series, Yellow
Bright, ergonomic, and built for comfort: these men’s boxer trunks in vibrant yellow feature a 3.2" inseam and mid-rise cut for a sleek and body-hugging fit. Ideal for daily wear, workouts, or travel.

A medium open pouch with angled side-entry fly provides natural positioning, easy access, and improved airflow. The pouch’s internal structure gently separates the genitals from the body, reducing stickiness, pressure, and overheating. No need for constant adjustment.

Made from a premium cotton-elastane blend (95% cotton, 5% elastane), this soft underwear offers breathable stretch, shape retention, and everyday durability. The wide gusset ensures anatomical alignment without tightness, while smooth hems and a soft 4 cm waistband keep everything in place without leaving marks.

Key Benefits:

Medium pouch with angled open fly – natural support and ventilation
Cooling effect – lowers skin temperature by up to 1.5°C
Breathable stretch fabric – premium alternative to typical cotton underwear
No-compression fit – wide gusset for free movement
Smooth-cut leg openings – no riding, no pinching
Soft waistband – firm hold, zero irritation

From the Silver Series, focused on minimal design, ergonomic fit, and everyday function. These yellow men’s boxer briefs bring bold color to high-performance premium underwear. A great choice if you’re looking to buy men’s underwear that’s stylish, soft, and built to move with you.

*Decorative stitching and color may slightly vary from product images.
