Turn garments inside out to preserve the integrity of the design. Use cold water only, and laundry detergent without bleach. Dry on low under normal settings. Expect about 5-7% (about a half a shirt size) shrinkage after a normal wash for our cotton shirts. Wash colors separately from whites, especially on the first wash.
Over time, you may experience slight fading on the graphic as your shirt naturally weathers with repeated washings.
