Give your old gear new life. 

We teamed up with ThredUp to help you shop and sell gently used Smartwool® styles that are ready for the next adventure outside.

Our Second Cut™ recycled wool program represents a significant step forward in our commitment to 2030 sustainability goal. By using sock fibers that have been reclaimed through our circular initiatives, we are able to create high-quality products with the added benefit of reducing our environmental footprint. Our new Second Cut™ Hike socks utilize the circular yarn blended with responsibly sourced ZQ Merino wool to provide all the performance, softness, and durability that our customers have come to expect from Smartwool. We believe that by embracing innovative solutions like recycled wool, we can create a more sustainable future for both our business and the planet.
