We love San Francisco. This t-shirt is buttery soft and lightweight, with the right amount of stretch. It's comfortable and flattering for both men and women. We use genuine Brother GT-3, water based pigment inks. GT-3 inks are CPSIA compliant and Oeko-Tex™ certified, which means they are safe to print on clothing and reduce environmental waste. Our tees are pre-shrunk so they will always fit. • 100% combed and ring-spun cotton (Heather colors contain polyester).
