The magic of the islands is alive well in this shirt. First, it reminds you of the special potion-beer-that makes dad the man his is. Plus, it also shows off our awesome alchemy that turns real American dollar bills into the dye for this mean green shirt. Made using our exclusive specialty dying process that uses real American currency 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.
