T-shirts are great, we all wear them. They keep your torso warm and covered, while letting your arms absorb some Vitamin D. But now we’ve absolutely revolutionized the idea of a t-shirt by adding your favorite jiu jitsu instructional cover to it. It’s amazing! Now you get all regular t-shirt benefits, but also a chance to represent the Encyclopedia off the mats! Super limited quantities, may only be available around the Anniversary Sale.
