The Southern Marsh Flying Vee Tee has a beautiful hand engraved impression of ducks flying in their iconic "V" flight formation. The "V" formation allows migratory birds to travel across continents quickly by giving updraft to each bird behind the leader, increasing efficiency and lessening the burden of flight. Similar to the way a hang glider can climb or maintain height indefinitely in rising air. Printed on our ultra soft, long staple cotton, washed for softness, and made with the finest quality materials.
