The PHOENIX performance sun hat was designed with moisture management and the need for freedom of arm movement around the head in mind. Our breathable tech fabric, perspiration absorbing mesh liner, and heat releasing vents, help keep the head cooler. We also addressed sweat dripping into the eyes by using the best technical head band we could find. The narrow brim shape protects the tips of the ears and the back of the neck from harmful UV rays, yet doesn't get in the way when active. A very stealthy look & style.
