A tarpon is a really big fish. You can try to catch one if you want, or you can just wear it on your shirt. The Patagonia Fitz Roy Tarpon T-Shirt is made from super soft and durable organic cotton with a screenprint logo. Plus, the cotton is U.S.-grown and the screen-print inks are PVC- and phthalate-free, so you can feel extra good about your purchase.
