Made in the Usa, The Iconic American Flag Sweater from Polo Ralph Lauren embodies Ralph Lauren's long-standing love of all-American style. The unisex sweater's 13 stars and stripes recall early American flags, including the one that flew over Fort McHenry during the War of 1812, which inspired Francis Scott Key to write ""The Star-Spangled Banner,"" and the restoration of which Ralph Lauren generously helped underwrite in 1998.
