*Please note we use dye sublimation on this product: Dye sublimation is a process of printing to fabric (and other substances) that provides the best quality, most durable printing option. In sublimation, the inks are fused into the fabric as opposed to sitting on top such as in inkjet or screen printing. The process not only gives fabrics a softer touch after the printing, but it is also very durable. The color remains strong in outdoor lighting and after extensive washing so it’s the ideal process for sportswear and school clothing.
