The everyday classic baseball-style cap you love meets the bug-repelling, cooling performance you need for a long, adventurous day outdoors in the ExOfficio BugsAway Sol Cool Classic Adjustable Cap. Odorless and invisible BugsAway technology is built right into the fabric, so you'll be protected against mosquitoes, ticks, fleas, and other insects. Sol Cool technology with jade-infused fibers will keep you dry and comfortable, absorbing the heat slowly and releasing it quickly so you can enjoy your sightseeing trip or trail trek from start to finish. You'll be able to wear this cap a few times and still feel fresh thanks to odor-resistant Silvadur technology. For a customized fit, simply adjust the pull-through strap in back.
