You can hear it coming...it's a hundred pairs of tiny wings flapping and it's coming toward you. BATNADO! This is one storm you may not want to go to bat against. You can ride it out in our Batnado crew socks, but you might want to grab an extra pair for your neck.* *Just kidding. Bats mostly eat bugs and fruit. These socks glow in the dark! Hold them up to light or walk outside before turning off the lights and watch the special thread glow. 58% Cotton, 40% Polyester, 2% Spandex. Approximately fits men's shoe size 7-13.
