Found this design somewhere and thought it might look cool. You can upgrade this tee to a Hoodie if you like. (Grey Hoodies are in stock) or have it printed on a white tee or hoodie which would look good.
This is a standard Athletic Heather / Sport Grey tees.
I usually use a Ring-spun Cotton Gildan Softstyle but due to covid, manufacturing has been weak and they are harder to get in all sizes. If the Gildan isn't available I've been ordering American Apparel and Port Authority, both of which are pretty similar and soft ring-spun cotton.
