Rule the water in this masculine swim shirt. The cool dual shark pattern is a subtle hint to this top's pair of looks. That's because 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. 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. 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.
