The Ventilated Sun Cap.

"This is the cap with two adjustable vent flaps that keep its wearer's head cool while providing UPF 50+ sun protection. The flaps flip up and conform to the shape of the crown, revealing the mesh vents for additional cooling. The contoured 3"" brim provides optimal protection from sun glare, while its folding, clamshell shape enables easy packing. The cap's integrated mesh sweatband extends 3"" high from the brim and 2"" high around the head, quickly wicking away moisture. Polyester construction. Adjustable hook-and-loop back. Sizes M and L. Blue. (2 oz.)"
