Lighten up! Someone should have told this cat that that is good advice when going hiking. It's also a good idea when buying a tee shirt, which is why we've been making funny shirts featuring Kliban's feline creations for over 40 years. Made from 100% cotton that is ring-spun then combed to remove impurities, this fabric is luxuriously soft and lightweight yet incredibly strong. 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-just like Kliban's cats-that stand the test of time as well as the bond between Crazy Shirts and The Cat has for all these years.
