After a successful collaboration with Acne Studios last month, British heritage brand Mulbery is back in headlines with news of their first entirely sustainable handbag. Named the Portobello Tote, the bag is manufactured entirely in the UK at Mulberry’s carbon-neutral Somerset factories.

The heavy grain leather used for the bag is a by-product of food production (so no animals were harmed during the process) and comes from a tannery with a gold-star rating from Leather Working Group, a leather-industry focused organization, on the basis of its environmental operations and output. The tote is unlined and has been stitched with Epic EcoVerde thread, a recycled polyester fibre.

“Our starting point for this family was the ultimate everyday item, the plastic bag – functional, but throwaway,” said Johnny Coca, Mulberry’s Creative Director, in a statement. “The Portobello keeps the beautiful utility of this silhouette and elevates it into an elegant tote that is practical and, more importantly, made to last.”
