the best $18.50 I've ever spent (OK, $55.50; I have three). It's just a piece of ziti-shaped, stretchy microfiber fabric, but you can twist it into anything: a neck gator, balaclava, scrunchie, headband, ear protector - even an emergency handkerchief. I rarely leave home without one; helps that they come in more than 100 colors and patterns. buffwear.com
