Limited-edition shirts available now!

T-shirts and sweatshirts make the perfect gift. This year we have a limited-edition Challenge Aerial shirts printed from a woodcut (see image above) designed by Atlanta-based artist Chris Neuenschwander. Place your orders here by November 15 to ensure they are ready for the holidays. The shopping interface is a little clunky, but you can email us at if you need some help ordering your cool (warm) new shirts.
