Custom Basketball Jerseys Basketball Singlets. By digital printing sublimation, Valkout Apparel always produces custom basketball uniforms. There is no minimum order requirement for our custom basketball uniforms, and there are no additional costs associated with adding player names, numbers, color, or any other decorations. We make custom sublimation basketball uniforms in all sizes for kids, teens, and adults. In addition to single custom sublimated basketball jerseys and reversible custom sublimated basketball jerseys, we are able to produce sublimation single and reversible custom basketball shortsas well. We typically use 140gsm, 100% polyester fabric for sublimated reversible basketball uniforms, which is lightweight and provides a better fit when sewing two single basketball jerseys or two single basketball shorts together.
