An animal t-shirt often sold at tourist shops in the U.S., most often printed with an airbrush look. CommonAlaska prints include wolves howling at the moon, bears showing some teeth and eagles descending. If you take pictures of these shirts in the night, the power glows.

A shirt (be it a tshirt, button down, tank top etc) that seems to have remarkable pulling power. The wearer will more likely than not hook up while wearing the shirt.
