INTRODUCING... SUN SHIRTS We are so happy to introduce MT Brand Apparel's newest item, Long Sleeve Hooded, UPF Protection Sun Shirts. We've teamed up the 100% Microfiber Polyester, moisture wicking with MT Brand Apparel's graphics. We will be printing our graphic with a sublimation process. Our VERY popular hat graphic is now being printed onto our new Sun Shirt. We will customize our Rainbow Trout graphic. We can include your location, favorite river, lake or stream. Please add your customization in the area provided. We will replace Salmon River or Missouri River with your custom idea. Sublimation printing is a digital printing method that uses heat and pressure to transfer a design onto a material by turning special inks into a gas, which then permanently bonds with the fabric or surface at a molecular level, creating a vibrant, long-lasting print that won't fade or crack; essentially, the image becomes part of the material rather than just sitting on top of it.
