The shirts are listed as 100% cotton. Care instructions recommend machine washing cold inside out with similar colors, tumble drying low or line/lay flat to dry, and note that hang-drying is recommended for best results.
The shirts are made-to-order and printed in the U.S.A. using digital direct-to-garment (DTG) printing with water-based inks.
The shirts are made-to-order, so customers should consider that when ordering multiple sizes. The listings also note printing is done in the U.S.A. using water-based inks.
