Durability is an often-overlooked aspect of sustainability; a product built to last is a more sustainable one. And that's exactly the story with the Berkeley Canvas Trousers. Not only is the heavyweight canvas tough and hardwearing - with reinforced back pockets and knee patches - we've also incorporated 50% recycled cotton into the mix for even better eco credentials. But to make sure they're not too stiff, they come pre-washed for added softness.
