We pioneered the concept of creating cutting edge slogans with eco friendly fabrics. Healing the earth and making fun of boys at the same time is our specialty. This daring design is printed on a blend of 70% bamboo and 30% organic cotton. It's super comfortable and it's cut at just the right length. Bamboo is one of the world's fastest growing plants and it does so without the use of chemicals or pesticides. It takes 1/3 of a pound of chemicals to create most conventional cotton tees. Think about how many of them are in your closet right now. Not only do you wear those chemicals on your skin, you eat them. Think about how often you've seen cottonseed oil in food ingredients. Buy one today and be able to sleep well tonight. Let the only ones getting a bad night's sleep be the poor guys you taunted during the day. But, at least you taunted them in style.
