Patagonia’s used clothing program is beginning to take off. The company has been gradually building out its own resale platform, Worn Wear. Now, the four-year-old service, which allows customers to sell their own Patagonia items and buy authenticated used ones, is having a “record year” in sales, according to the company. Worn Wear has also seen “record sales months” for its up-cycled collection, called ReCrafted, which launched in November 2019, according to the company. It’s been quite the year for used and second hand marketplaces. Resale platforms — including Poshmark, ThredUP and Mercari — reported major uptick in growth. But Patagonia opted to build its own service to be able to buy back inventory, authenticate and resell it to enthusiastic customers.
