The word Pohaku is used in reference to the beginning of Hawaiian culture, evidence of which comes in the form of the petroglyphs found carved into the lava beds on the islands. This shirt brings that artwork into the present by screen printing this ancient artwork onto our crater dyed tees. 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.
