What Our Gearhead(R) Experts Are Saying:"I've run in a lot of sun hats and the Sun Runner Cap is one of the few that actually stays comfortable for a full long run in direct sun. The removable cape is the standout feature for me - it adds real neck and shoulder coverage without trapping heat, and when conditions change I can pull it off in seconds."Long summer miles under a relentless sun call for more than just a brim. The Outdoor Research Sun Runner Cap wraps around the full picture, putting lightweight, breathable coverage exactly where it's needed most so heat and UV exposure stop being things to manage mid-run. Supplex nylon keeps the whole cap quick-drying and moisture-wicking, and the TransAction headband pulls sweat away before it becomes a distraction. The removable sun skirt extends protection down the neck and shoulders on exposed ridgelines or shadeless desert trails, and it comes off just as easily when you duck into the trees. Mesh panels keep airflow moving throughout, while the optional chin cord holds everything in place when the wind picks up. For high-output days in full sun, this cap covers all the bases - literally.
