The Yupoong 6606 snapback trucker cap is a staple in custom headwear, designed with a six-panel, mid-profile build that combines structure with an easy fit. Its pre-curved Permacurv® visor with a matching undervisor keeps its shape while maintaining the classic trucker style. A cotton sweatband provides comfort during long wear by absorbing moisture, and the cotton-poly front with a breathable polyester mesh back balances softness, durability, and ventilation. With its consistent fit and embroidery-friendly design, the Yupoong 6606 is a trusted choice for branding, retail, and everyday use.
