Island Planet Headbands have been popular for years--they're great for keeping your hair out of your eyes and will open wide enough to cover the top of your head to provide some shade! Our innovative and imaginative customers started wearing these to cover their noses and mouths as well as for headbands! And did this catch on!! When not in use, just drop it down and it rests around your neck, ready for the next use. A super accessory to any outfit!!
