The ExOfficio Women's BugsAway Packable Sun Hat offers protection from bugs and the sun when you need it and easily stores away when you don't. This hat is a great just-in-case addition to your next adventure. 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 safari trek from start to finish. For a customized fit, simply adjust the chin cord. The packable design takes up less space in your carry-on or suitcase.
