Did you know humpbacks are known to show compassion for other whales and even other sea animals? That kind of altruism needs to be celebrated and what better way to do it than on a key lime dyed t-shirt. Made using our exclusive specialty dying process that uses real key lime juice 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.
