For standard t-shirts and long-sleeve shirts, I use Bella Canvas because they are soft unisex cut shirts that are flattering to both women and men. Solid colors are made with pre-shrunk 4.2oz 100% airlume combed and ring-spun cotton. Heather colors feature 4.2 oz., 52% airlume combed and ring-spun cotton, 48% polyester while Athletic Heather is 90% airlume combed and ring-spun cotton, 10% polyester.
