Most t-shirts are Gildan super-soft cotton polyester rayon. They do not have a tag, the shirt info is printed on the shirt. This is a lighter weight shirt that does not shrink, less likely to wrinkle, and it lays nice on the body.
If you are looking for 100% cotton let us know and we can most likely use that on most designs.
This design has a slightly soft feel to it, will wash and wear for a long time.
