The Canadian sportswear retailer said Wednesday it will launch yoga mats and bags made from Mylo — a mushroom-based leather alternative developed by biomaterials maker Bolt Threads. The company said the bags will go on sale in early 2022, and has not yet revealed when the mats will be available.

The announcement comes as part of Lululemon’s wider sustainability and material innovation strategy, including the launch of a resale programme in April of this year.

Lululemon first revealed plans to make products from the renewable Mylo material last October, announcing it would join the Mylo consortium, a partnership of retailers who have invested in and secured exclusive access to the Mylo material. The consortium also counts Stella McCartney, Adidas and Kering as members. The three companies have yet to announce launch dates for the commercial rollout of their Mylo products.
