The incredible rich hue can only be produced by 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.
