Doubling is Sebago’s classic striped cotton Oxford shirt. The button-down style was originally born on the polo field in the late 1800s, going on to become a style icon amongst American college students, British mods and VIP films stars. Sebago presents this elegant iteration with a pocket on the chest, darts on the sleeve and a rear hanging loop. A logo label on the inner placket adds a dose of unmistakable Sebago style. The Doubling shirt owes its name from the historical namesake lighthouse established on the Kennebec River in Arrowsic, near the busy shipbuilding harbor of Bath, Maine, in 1898.
