The Huk ICON X is one of the most popular fishing shirts available. When you wear this comfortable, perfect-fitting, sun-blocking +30 UPF crew you'll be wearing apparel that not only looks great, but is built from state-of-the-art fabrics, durable poly-knit construction and most advanced materials for protection against the elements. Huk proudly introduces their latest women's ICON X long sleeve featuring their Internal Cooling Element (I.C.E) technology - engineered at the fiber level to cause an endothermic reaction once there is any contact with moisture (sweat) causing your body temperature to drop in minutes.
