These navy trunks are crafted from a breathable cotton-elastane blend (95% cotton / 5% elastane) that combines softness with flexibility for all-day wear. The three-part anatomical pouch with horizontal fly provides fast one-handed access and provides extra space without pressure. A wide internal curtain ensures stable separation, while the reinforced gusset adapts to movement. Seam-free sides reduce friction under clothing, and elastic leg hems keep the fit secure, preventing ride-up. Designed for sport, office life, or casual use, these trunks deliver consistent comfort and support.
