Dyed using organic dyes with designs printed with soft, non-toxic water-based inks. When you first receive your Aircraft Carrier shirt, we recommend washing in cold water alone or with like colors. Since your shirt was hand-dyed it will continue to bleed some excess color for the first few washes. It is safe to use normal detergent, just make sure to avoid bleach. Your mighty Aircraft Carrier shirt should be dried either in a tumble dryer or flat, not hung as the weight of the water will cause the cotton to stretch.
