Deus Vacay Check Shirt (Maui Check). Does anything scream the bliss of a surf-soaked winter louder than a classic, oversized flannel? The Vacay Check Shirt is perfect for morning surf checks and casual Fridays alike. Made from 100% Cotton that's warm as toast but breathes as well. We’ve taken ample care over the details - woven clip label, real horn buttons - and the result is a flannel that's set to be a reliable companion for many winters to come.
