PowerStretch Trunks 3.9" – Silver Series, White
Minimalist, supportive, and built for daily comfort: these men’s trunks underwear feature a 3.9" inseam and mid-rise fit with a clean, close-to-body silhouette. Designed for men who value structure, privacy, and soft support in any setting.

A medium-sized closed anatomical pouch offers gentle isolation and full containment. With no fly and no external access, it’s made for those who prefer discreet support and stability. Internal panels hold the anatomy in a natural position, reducing pressure, friction, and the need for adjustment throughout the day.

Crafted from a soft stretch cotton blend (95% cotton, 5% elastane), these premium underwear trunks combine breathable comfort and long-lasting form. The lowered front eliminates any pressure on the abdomen, while the wide gusset ensures freedom of movement without tightness. Clean-cut hems prevent digging or rolling, and the 4 cm soft waistband provides a secure hold without leaving any marks on the skin.

Key Benefits:

Closed anatomical pouch – private support, no access
Medium internal panels – stable positioning, zero shift
Cooling tech – helps lower body temperature by up to 1.5°C
Breathable stretch fabric – soft and durable alternative to basic cotton underwear
Mid-rise with 3.9" inseam – short, modern boxer trunks cut
Wide gusset & no-elastic hems – full range of motion
Soft 4 cm waistband – secure grip, no pinching

Part of the Silver Series, a refined line of men’s underwear focused on minimalism, ergonomic design, and long-wear comfort. These clean white trunks are a smart choice for men seeking premium underwear that delivers privacy, support, and structure.

Looking to buy men’s underwear that’s functional, soft, and built for movement? This is the one.
