The Pu'u Loa petroglyph field on Kilauea is considered sacred by Hawaiians and is one of the best places to see these powerful works of art. Powerful in a different sense is the volcano these motifs call home, and we've done our best to use this ancient style of art to depict the exclusivity of this island landmark. Made using our exclusive specialty dying process that uses real volcanic ash and featuring 100% combed ring-spun cotton, this tank 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.
