This humorous design will have them rolling one way or another. Of course, we had to put this one on our on Hemp-dyed material-our name is Crazy Shirts after all. Made using our exclusive specialty dying process that features real industrial hemp and featuring 100% combed ring-spun cotton, this t-shirt has 50+ SPF protection to keep you feeling cool, calm and protected all year long. We only use environmentally friendly water-based inks that penetrate the material's fiber resulting in more vibrant colors, softer feel and artwork that doesn't crack or peel. Plus, it is proudly printed in the United States for quality you can see and designs that stand the test of time.
