Part of the Bad Elements line, this mock neck is engineered to perform as a base layer, a standalone piece, or the layer that sits under a quarter-zip when the temperature drops. Built from 88% polyester and 12% spandex with 4-way stretch, it moves with every swing, reach, and turn. A permanent cooling system is woven directly into every fiber so it never washes out, and unique fiber channels pull sweat away from the skin quickly for lasting comfort round after round. UPF 50+ shields you through long days in the sun, advanced anti-odor protection keeps you feeling fresh, and wrinkle-resistant construction holds a clean, polished look from the first tee through the final hole.
