After just one wash you will not know where the print ends and the shirt begins. Our unique printing process actually pulls the dye color out of the shirt and leaves the ink color behind, essentially dyeing the cotton with the ink. After dyeing they are washed and dried, so they arrive to you comfortable, preshrunk & ready to wear.
