Once you put your tshirt in the cart, you can UPGRADE for a long sleeve tshirt. Both the original design plus this must be in your cart for us to upgrade to your sweatshirt. You will not receive two shirts...your tshirt will be swapped out for the upgraded long sleeve. 
 
If you need a different color long sleeve, please indicate in notes. 
 
Important: The long sleeves are UNISEX (meaning that they run BIG), therefore size down and check the size charts. Although they begin at size small, if you need something smaller (similar to a XS), the YOUTH Large shirt will be substituted for XS Unisex Adult.
