Printed on an American Apparel fine ring-spun combed cotton shirt. I use fully water based cream colored ink so you get a super soft, great fitting shirt that's not only built to last but is environmentally friendly too. I can print this design on several other color shirts, some are visible here: http://www.etsy.com/shop/missionthread?ref=seller_info so drop me a line if you want and I can print a custom for you. Standard t shirt sizing, have a look at the chart in the pictures. I ship very fast, usually today or the next business day. Have a look at my feedback and see you'll be getting a great shirt and service! Thanks for stopping by!
