Huk calls its new NXTLVL Woven Shirt the "most technological button-down." The company uses a technology on the inside of the material that creates an endothermic reaction when it contacts moisture, such as sweat. The reaction generates a 10-degree temperature drop over a three-minute period. The shirts also feature branded buttons, snap-down pocket flaps, K.C. Scott signature artwork, sun protection and mesh venting. The NXTLVL Woven Shirt comes in short- or long-sleeved styles ($59.99 and $64.99), six colors, and sizes S to XXXL.
