The intrepid Polynesian seafarers who discovered and settled Hawaiian used Kamani wood to make the keels of their boats. These strong timbers served as the backbone of their canoes just as this is the perfect shirt to build your active beach lifestyle around. Lightweight and offering 50+ UPF protection that blocks out 98% of the sun's harmful UV rays, it is comfortable and safe to wear in the water all day long. This innovative design also contains a hidden pattern when wet, but since it is quick drying you'll have to be on the lookout to see it. Made from a combination of recycled plastic bottles and spandex, it's no stretch to say you'll be comfortable wearing this shirt for more than one reason.
