This practical classic-style hat is designed for comfort and sun protection. It has a mesh strip in the crown that lets air circulate to help keep your head cool, and a built-in sweatband to wick away moisture from your forehead. Providing a UV protection factor (UPF) rating of 50+ (mesh included), it has a brim that measures 2 3/4" wide on the front and back and 2" on the sides; dark fabric under the front brim reduces glare.
