4F Seamless Underwear for Boys M248 Deep Black 128-134 cm

Seamless construction with high-stretch polyester-elastane blend delivers chafe-free comfort for active boys. The deep black base layer fits close to the body, wicks moisture, and stays breathable through sports and daily wear.

Overview

The 4F M248 seamless underwear is built for boys who move. The fabric stretches in every direction and returns to shape, while the elastic waistband keeps the fit secure without digging in. Flat seams are eliminated entirely, so there is no rubbing against skin during running, jumping, or long school days.

• Breathable fabric allows air circulation to keep the wearer cool
• High-stretch material moves with the body and retains its shape
