I had the hat four days festival use. It protects equally well against the blazing sun, as moderate rain, yet is well ventilated. One should actually order one size larger, as it turns out a little small and is provided with an indication that an initially loose fit of the hat is necessary in order to ensure permanently good wearing comfort. The only drawback is the somewhat oblique processing, whereby the front vent hole will slip slightly to the side and the hat with folded up screen (lateral push buttons are available) comes slightly asymmetrical.
