Our editors curate highly rated brands that are first assessed by our rigorous ratings system. Buying through our links may earn us a commission—supporting the work we do. Learn more.

Culottes, wide-legs, barrel-legs, straight fits, you name it. Pants or trousers come in many shapes and forms, and we’ve rounded up our favourite, more ethical brands to bookmark for when you need to invest in a new pair.

Pants and trousers by better brands

Trousers are a building block of most wardrobes and come in so many different cuts and fabrics. Think comfy wide-leg jersey culottes, linen straight legs, smart pleated office trousers, and more trend-driven shapes like the popular barrel leg or ultra wide cut.

If you buy a good pair of trousers that’s made well and from a quality material, you can expect them to last years of regular wear. Especially when they’re cared for correctly and mended when needed. Often, though, fast fashion options are produced quickly with little concern for whether the stitching or elastic is going to last, and are usually made from synthetic fibres like polyester and nylon that aren’t breathable to wear, nevermind their lasting impact on the environment.

With that in mind, our editors have curated options from some of the top-rated brands in Good On You’s directory. They’re businesses that are working hard to be transparent about their practices and improve their impact. Some are vegan, some prioritise labour justice, and others eschew synthetics completely. So if you’re looking for more sustainable trousers and pants, scroll on to discover them.

Looking for options better suited to your height? Check out our guides for brands selling petite and tall trousers.
