We use 100% organic cotton for our CC Active hoodie. Organic cotton is a natural, renewable, and biodegradable fiber and is an environmentally friendly alternative to regular cotton. The toxic pesticides, fertilizers, and chemicals used to grow regular cotton have some of the highest toxicity levels known to humans and harm the planet's air, water, and soil. Organic cotton production relies on none of those chemicals and uses 88% less water than regular cotton, reducing the pressure on the planet's water supplies.
