Photo T-shirts Hanes SoftLink T-shirts are made from a very light, soft and durable blend of polyester and cotton. They are polyester on the outside for a good screen and cotton inside for softness. Bright white and short-sleeved. Photos can be wider than tall, and must have at least 1500 pixels by 1100 pixels. T-shirts have satisfactory color reproduction, but not as accurate as photographic prints or hard-surface gifts like buttons.
