Organic cotton is produced using techniques that are healthy and safe for the environment and the people who work and live near the fields where it's grown. Organic cotton is never grown with synthetic chemical fertilizers, pesticides, herbicides or defoliants, nor is it genetically modified in any way.
At Patagonia they seek to build the best product and cause no unnecessary harm. That's their mission statement, and it takes many forms. As it applies to making products, Patagonia works hard to source materials and use processes that are less harmful to the Earth without compromising quality.
