“This hat turns a neat trick: Top-mounted vents can be flipped open on exceptionally hot days or left closed if you want full protection from the sun. The curved lines on the side make it comfortable on long runs, and it doesn’t interfere with sunglasses. The foldable bill dials up usefulness, so you can pack it flat in your gym bag—or tuck it in the waistband of your shorts, if you need to ditch it mid-run.”

We wanted an ultimate performance cap, so we crammed a bunch of our favorite technologies into the Eclipse. Our Convertible Ventilation™ system covers for sun protection and opens up when airflow is needed. The Clamshell Brim™ lets you stow it away in your back pocket or the farthest reaches of your suitcase. Ear-friendly design keeps you comfy until the end of the road.
