This is the short-sleeved shirt with a built-in patented ventilation system that ensures its wearer stays cool as if in a cross breeze. Zippered vents below the arms allow air to enter the shirt and two zippered vents above the shoulders allow warm air to escape, creating an efficient air flow that keeps wearers comfortable, unlike shirts that allow heat to build. The two front pockets secure with hook-and-loop fasteners and are lined with mesh to provide efficient air flow while its vented back provides further escape for warm air, allowing perspiration to evaporate more efficiently. Its hidden, button-down collar rolls up to provide complete neck coverage. The shirt's quick-drying 100% nylon fabric repels water, resists stains, and provides UPF 50+ protection. Tan. Sizes S (44), M (48) and L (52). (2 oz.)
