Haleakala, Hawaii's most famous volcano, is known as the "House of the Sun" thanks to its spectacular sunrises. Dyed using real volcanic ash, this shirt pays ode to the legend of Maui, who lassoed the sun from Haleakala to lengthen the day and keep us warm and give everyone a chance to wear cool Ts like this. 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.
