Mammut Runbold Cap

Like your mother always said, "don't sweat the small stuff." Keep your noggin cool, calm, and collected with the Mammut Runbold Cap. Crafted with 40+ UPF technology, this hat protects you from the sun's harmful rays while the E.Cooline fabric wicks away moisture and dries quickly. Additionally, the cap is equipped with a hook-and-loop pad located on the interior of the forehead: this pad can be soaked in water prior to your run or hike, which in turn keeps you cool throughout the course of your adventure.
