The HukA(R) Icon X Long Sleeve Crew Tee is the most technically advanced performance fishing shirt designed for hardcore anglers. It's made with Huk's I.C.E. Cooling Techology. I.C.E. stands for Internal Cooling Element and it has been 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. In simpler terms, when you get hot, you sweat. The fibers then absorb that moisture, wick it away which creates a cooling effect. You feel cooler, your shirt feels cooler to the touch, and its wicking and quick drying to keep you comfortable. 100% polyester I.C.E.
