As a brand built on natural performance materials, Smartwool continues to look towards nature for inspiration and innovation. As part of our 2030 Social Impact roadmap, we are working towards having our products made completely from responsibly sourced renewable-based materials. We’re looking to give more to the planet than we take. By using less chemicals, water and energy, our natural plant-based dyes, made from renewable plants, are a great step forward on our sustainability journey.
