Frolich Krampus Tag to you! The Krampus is a beast from European cultural traditions that appears in towns as far away as Russia, Argentina and even Pennsylvania. Representing the dangerous side of the Santa myth, Krampus will beat or even take away children who have been naughty. There's even a KrampusTag holiday, December 5, that like Christmas stretches on for the days that follow. Wear this unabashed Krampus Shirt for your next Krampuslauf.
