(For Double Sided Print, Select "PREMIUM or ULTRA PREMIUM" at check out). (For Single Side Print, Select "STANDARD at check out") OUR DOUBLE SIDED PRINTED T-SHIRTS AND OTHER PRODUCTS ARE PRINTED ON PREMIUM MATERIAL. Most of our products are printed on the highest quality 100% spun polyester; last 100 times longer than cotton products. “All-Over-Printing,” allows for designs to be placed across the entirety of a product, without any limitations in color. When all-over-printing is applied to fabric, you can expect a soft to the hand touch, and for the apparel to never crack, peel, fade, or wrinkle.
