As mentioned in the other comment, it rocks how versatile this hat is. I find myself using it all the time for running, hiking, and casual wear without the neck guard. Super light and breathable. My big complaint is the white under brim. A hat with sun protection seems perfect for mountain use (and looks good so you actually want to use it), until the glare from the bright white under brim filters perfectly under the top of sunglasses. Small change that would make the hat perfect.
