The Navy Honu UV Shirt is a perfect addition to your beach attire. Honu means turtle in Hawaiian. The design of the shirt is exclusive to our store, and designed by our owner! The fabric has a UPF rating of over 50, which is comparable to wearing SPF 150 sun block. These UV shirts are also made of a water repellent fabric, which will allows extremely fast drying times, as well as wick away sweat. If you get cold in the water, these UV shirts are enough to keep you several degrees warmer. These UV shirts are cut just like a t-shirt, which is much less constricting than your typical rash guard. These shirts are perfect for any outdoor activity, from swimming, to biking. From mowing the lawn, to scoring some waves at your favorite break. UV shirts are really good for just about anything. MADE IN THE USA.
