Sustainability

Running Responsibly

We are committed to a long-term, science-based approach to sustainability. We know it’s time to think bigger about the impact our products and their full life cycle have on people and the planet.

SUSTAINABILITY METRICS

Percentage of recycled content

• This metric refers to the percentage of material by weight that has been recycled from post- or pre-consumer sources.

Number of plastic bottles

• Our roadmap to use recycled raw materials initially focuses on post-consumer sources, such as plastic bottles.
• With help from our suppliers, we calculate the number of plastic bottles used to make a size medium of each product.

OUR PRIORITIES

Climate action

We are using sound science to address climate change and align our efforts across every level of our business to reduce carbon emissions. This includes product designs, materialization, manufacturing, and our global supply chain.

Sustainable consumption

As we create new gear and run our global business, we also want to minimize our impact on the planet — so we are limiting our reliance on non-renewable resources by using more sustainable materials and reducing waste.
