With sustainability at the forefront of our values, most of our tees are made from 100% certified organic cotton. Organic cotton produces fewer greenhouse gases and typically relies on rainwater for growth, decreasing water waste. It is also grown without pesticides or insecticides - making it a safer option for workers and the planet.A few of our products are 100% cotton (not organic) and some an eco-blend of RPET Recycled Polyester, and 37% Combed Ring-Spun Organic Cotton. Please see each product on our website for the specific garment!
