We use 100% cotton heavyweight t-shirts, sweatshirts and other garments unless you request otherwise. If you want a specific brand of apparel, let us know and we can get it for you. You can upgrade to American Apparel, Champion or Hanes Beefy t-shirts for only a little bit more on custom screen printing orders (subject to color availability). Ask your sales representative for more details.
Most other clothing is also 100% cotton, but some garments (hats, jackets, etc.) are made of different materials.
