As you can tell from the pictures this cool design is of a cell phone with a NA recovery App loaded on the back of the shirt. The is a cool blue NA Service Symbol on the left front Corner. The app is set-up like a 10th Step daily inventory list. It is like a recovery check list of things to do. We just thought it was a cool idea so we created it. These shirts are made of 100% preshrunk cotton. The image measures 6" x 10.5". Please pay close attention to the image size as it may look different then the image size in the picture of your size.
