Made from organic cotton & bamboo/organic cotton blends, and screenprinted by hand using water-based non-toxic inks, these mindful tees remind onlookers to laugh more, be happy, act nice & to chill. "As you know, these sustainable materials are much better for everyone - the earth, the workers and the person wearing the shirt," explains TeesForChange.com's Andreea. "In addition, we also plant a tree for every shirt we sell!"
