The original single-layer knit balaclava. Often imitated, sometimes duplicated... wait... but never with as awesome of a name as the original... the Terryclava! Sure, you might be able to find other single-layer acrylic balaclavas out there, but do they have a small percentage of pterodactyl DNA woven into the very fiber of their existence? Nay! And hence ask yourself, will they help you fly as high?
