Printed on super soft vintage tees. 100% polyester. All-Over-Printing (Sublimation). Design is printed on a sheet of high-release paper and transferred onto this T-shirt using a high heat and pressure system. Heat converts the solid, printed dye particles into a gas and bonds them to the polyester fibers in the T-shirt. The dye is absorbed by the fabric allowing for a more breathable, softer feel. Made in the USA.
