This Summer tee is made of 100% Sheer Jersey cotton (Heather Grey contains 10% Polyester). The fabric weight is 3.8 oz/yd² (129 g/m²). It produces good screen printing results! Pre-shrunk and laundered, this 100% cotton Sheer Jersey is combed for softness and comfort and comprised of loosely knit 40-singles yarn. This fabric has both a subtle stretch and a delicate texture! With a durable rib neckband, this tee fits slimmer than the American Apparel 2001. Unisex sizing means that men will need to order a size up and women may need to order a size down.
