From popularizing surfing in Australia and California to winning Olympic medals in three European cities, no one did more to bring Hawaii and its culture to the world then Duke. This smiling design conveys his warmth and openness allowing you to be your own Ambassador of Aloha wherever you wear it. Made using our exclusive specialty dying process that uses real volcanic ash and featuring 100% combed ring-spun cotton, this t-shirt has 50+ SPF protection to keep you feeling cool, calm and protected all year long. We only use environmentally friendly water-based inks that penetrate the material's fiber resulting in more vibrant colors, softer feel and artwork that doesn't crack or peel. Plus, it is proudly printed in the United States for quality you can see and designs that stand the test of time.
