To ensure that this headband is as well prepared for warm weather and challenging adventures as you are, we built it using our favorite new active fabric technology—Comfort Shell Lite Supersoft. Soft and light like cotton but airy, moisture-wicking, and quick-drying for high output adventures, this headband thrives in warm weather and helps keep your temperature regulated as you run, hike, or bike up a sweat. And the best part? It gets even cooler! Its absorbent construction soaks up water in a flash, so a quick dunk in a trailside stream or mountain lake is all you need to give yourself a serious cooldown and get back to enjoying your summer fun.
