Smartwool, the manufacturer of merino wool activewear says that socks will play a key role when it comes to meeting its strategic goal of making all products circular by 2030. The Denver, US-based firm has launched the Smartwool Second Cut Project which is designed to give products a “second cut” at life and will help create a more circular supply chain that extends the life of raw materials, presents a new sourcing stream, and reduces environmental impact. The project represents a significant pillar of the brand’s newly defined 10-year social impact goals and will be launching with an Earth Day timed sock take back event.
