Behind The Design

Our Giving Model

Giving is core to who we are. We tie our earnings to impact by allocating 1% of annual revenues to the Cotopaxi Foundation, which then distributes multi-year grants to thoroughly vetted nonprofit organizations who focus on improving the human condition and fighting extreme poverty. Since 2014, we have helped our impact partners reach an estimated 3 million people in extreme poverty through traceable and valid means.

Behind The Design

Designing For Sustainability

Impact starts with how we make our products. That means taking ethics into account during every phase of a product’s lifecycle—from its design to its manufacture and sale. Designing for sustainability is our priority, and we aim to create products you’ll wear for years to come. As part of the Sustainable Apparel Coalition, we have the tools to audit our suppliers to the highest standard. Beyond agreeing to our rigorous code of conduct—which protects workers and insists on fair wages—all of our suppliers are dedicated to best-in-class practices across the board.
