Our thermal indigo long sleeve polo shirt will become your "go-to" for everyday wear, whether you're at sea or ashore. With a classic, but modern fit, it is universally comfortable and flattering. The unique one-button collar and placard roles to just the right stance. The body fits true to size and the sleeve is tailored to a perfect length. With a slightly weathered finish, our 100% indigo-dyed cotton will continue to fade and wear in beautifully over time.
