Among the dozens of indelible visuals from National Lampoon's Christmas Vacation is the image of Clark and family hauling an oversized tree home atop the Griswold family station wagon. Instead of a bulbous Taurus, these hats depict the scene using classic SUVs from the past. Led by a Range Rover Classic,the collection also includes a tree-topped Jeep Wagoneer — which most resembles the Griswold's wood-paneled rides — and Land Rover Defender. The hats themselves are made from ultra-soft, cashmere-like lightweight cotton flannel, with an unstructured low-profile silhouette and a real leather adjustable backstrap with antiqued metal slider.
