Both shirts carry the front and back prints shown. Thunder Blue and Chili Red are featured in the design. We'll put your own GP number on both our badges for you. Or...if you don't own a GP-- take "2006." 100% Cotton inner surface. Poly outer surface for maximum color life and durability. A very comfortable shirt that will last years and look great--wash after wash. I've been told these shirts run a bit on the large side.
