Saucony is going sustainable. The brand, mostly known for its wide selection of running shoes, is releasing a new, sustainable  fabrication to its running apparel offerings.

The Wolverine World Wide subsidiary partnered with Los Angeles material innovation startup Ambercycle — which converts end-of-life textile waste into new yarns for apparel brands and manufacturers — to bring recycled polyester to a small assortment of performance gear, according to a press release shared by Sourcing Journal. The capsule will include men’s and women’s apparel and will be comprised of four different tops: a fitted tank, crop top, short sleeve, and singlet. Each features a component made of up to 23% cycora material. Cycora is made from material sources that are regenerated and re-engineered through the Ambercycle Ecosystem. According to the cycora website, “We enable true circularity by purifying fibers within garments on a molecular level and reprocessing them as brand new.”

The partnership is cycora’s debut in the performance apparel market, according to Ambercycle CEO Shay Sethi. “With this collaboration, we are inviting the global running community to help build a circularity ecosystem, where performance apparel is removed from the cycle of waste and reused over and over,” he said in a statement.

Brian Moore, Saucony vice president of global product, said in the press release that the collection represents the next step in the brand’s “commitment to protect our planet.” After the debut of its zero-plastic Jazz Court RFG sneaker, made with cotton, lyocell and wool, Saucony announced in 2021 plans to begin using 100% recycled uppers. By 2024, the brand has a goal to fully move away from virgin plastic.
