Committed to circularity

Circular & Recycled Wool

Second Cut™ Project

We’re giving old products new life to eliminate the need for new materials and keep perfectly good materials from being thrown away. Let’s go green before we go far. And close the loop together.

Give your Smartwool gear new life

We teamed up with ThredUp to help you find tons of gently used Smartwool® styles that are ready for a second life in the great outdoors. You can also send in your old gear to Thredup through the Second Cut™ Resale program, and when it sells we’ll send you a Smartwool gift card.

Second Cut™ Resale

Recycle your socks

Old socks don’t have to be thrown away anymore. You can order a free sock recycling kit from us, print your own label at home, or find a participating retailer near you.
