Commissioned after Pearl Harbor, the Mighty Mo is proof that the attack only served to make America bigger and better. After 50 years of protecting the United States, it now resides in Pearl Harbor where it stands as a testament to courage, honor and sacrifice. 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.
