Krypto-lite t-shirts are printed on Hanes Beefy-T t-shirts. They provide a quality canvas that fit true to size, shrink very little, and resist fading. A little t-shirt humor wouldn't be complete without the mention of zombies and ninjas. I currently have several sizes available in the original "Zombie Repellent Device" print. Shirts featuring the "Ninja Supply Warehouse" logo will be available soon.
