These graphite trunks combine a cotton-rich fabric (95% cotton / 5% elastane) with a supportive cut that moves naturally with the body. The three-panel pouch with a horizontal fly offers fast one-handed access and extra room without compression. A wide internal curtain keeps separation stable, while the reinforced gusset adapts to motion. Seam-free sides reduce skin contact, and elastic leg hems lock the fit in place to prevent ride-up. The lightweight cotton surface stays breathable, while elastane adds flexibility, making these trunks a dependable choice for training, office life, or everyday wear.
