Just think about all those birdies you're going to rack up while wearing this Callaway birdseye short sleeve polo shirt from the Standard Collection, which fuses Callaway's most classic look into a roomier fit. Birdseye patterning is created by weaving small diamond dots into the fabric, resembling a bird's eye. Callaway's Opti-Dri moisture wicking technology pulls sweat away from your body to keep you cool in the heat, cooling technology transfers heat away from your body to keep the garment cool and UPF 15 provides superior protection by blocking the sun's harmful UV rays.
