In menswear, t-shirts are the default product you see (except for the Signature design which is only available for use on a Jersey Polo Shirt or a Full-zip Hoodie) and they are in a single color, but once you have chosen a design, you can choose between several other types of clothing (styles) such as sweatshirts, hoodies, sleeveless t-shirts and many others. You can also change the color of the product you choose of course. Of every design there are always two versions. The rule here is that for products in dark colors it is best to use the design with the white letters and for products in light colors use the alternative design with the black letters.
