DAG Gear Booney Hat is a real boon on hot, sunny days. Based on the model used to keep U.S. troops cool and protected in sweltering conditions, our Ventilated Booney Hat features screened "port holes" and 360° vents in the outer crown to capture the slightest breath of a breeze. Mesh lining and sweatband feel fresh as you work up a head of steam. Wide 3" brim provides shade anywhere and snaps up on sides when you want it out of the way, while the UPF 50 shields your noggin.
