For high-intensity cold-weather activities, you might not want or need the thickness and protection of some other hats. Instead, turn to the Reflective Lid, which offers the thermoregulation, moisture management, breathability, and odor control of responsibly sourced Merino wool in just a single layer. Plus, for low-light conditions, it has knit-in reflective elements. | Smartwool Reflective Lid in Black
