Follow these instructions and your t-shirts will keep their vibrant colors longer than the changing leaves on your family tree!

• Wash and dry your t-shirts inside out. It's a simple yet crucial step.
• Opt for low-warm temperatures and gentle detergents. Your shirt isn't a summer barbecue, so avoid high heat!
• Resist the temptation to spin excessively. Extra spins can lead to more wear and tear.
• Air dry your t-shirts whenever possible. If tumble drying, dry on a low setting and avoid heavyweight companions like winter coats and blankets.
• Iron your t-shirts inside out on a low heat setting. Designs and irons aren't always the best of friends.
• Do not dry clean.
