Sustainably sourced materials

At COS, we believe in investing in the now to design for the future. That’s why we are committed to sourcing quality materials that will have less impact on the environment.

So far in 2022, 92% of the base fabrics in our collection are more sustainably sourced, according to our Material Environmental Benchmark. We’re also working towards making all the trims we use more sustainable too. Our goal? To use only 100% sustainably sourced or recycled materials by 2025.

There are all kinds of fabrics in our collections that are more sustainably sourced, and we highlight these so you can make considered choices when you shop.


Organic

Organic materials are grown from organic seeds, which have not been genetically modified in any way. The cultivation process requires no synthetic fertilisers, protecting both our planet and its people.

We’re also exploring new technologies and production methods, such as processes that use less water and regenerative organic farming that prioritises restoring soil health to help fight climate change.

*Though this figure is lower than in previous years, this season we are introducing more responsibly sourced fibres into our collection. Watch this space for regenerative cotton and greenhouse-grown cotton by Materra.

Recycled & repurposed

By giving a new life to leftover fabrics through recycling and repurposing, we can reduce our demand on the planet’s limited natural resources.

Recycled fabrics are made using the waste from both the pre- and post-consumer stage of a product’s life.

The pre-consumer stage happens before the product is made, gathering waste from yarn spinning and cuttings from the production process. Post-consumer refers to the stage at the end of the product’s life. This could be unused clothing, textiles or even things like carpets, all of which can be made into new clothes. All the recycled materials we use are certified according to the Global Recycle Standard (GRS) and Recycled Claim Standard (RCS).

Repurposed fabrics are made from gathering our own cutting waste, recycling it to make new repurposed pieces from the cotton, wool and cashmere in our collections.

Due to the complexity of the repurposing process, there aren’t many brands of our size doing this. There's lots more we can do but we’re proud to be leading the way.

We seek out new production methods and innovative ways to bring a higher proportion of recycled fibres into our compositions and retain the quality feel you love. We aim to source 30% recycled materials by 2025.

Conventional

We believe every piece should have a long lifespan. To make sure the materials in our collections meet our high-quality standards, we use conventional fabrics such as leather and silk, while constantly searching for better alternatives and pushing the industry to improve.

Most of the synthetics we use have been converted into recycled alternatives and we are making the transition to organic silk as well. We’re also working towards making sure all of the leather in our collection is chrome free: a cleaner tanning method that’s kinder to the planet.

Natural vs synthetic

When choosing our fabrics at COS, we don’t just select them because they’re natural or organic, we look at how they will perform when our customers wear them, too. That’s why we need a balance between using natural fibres, such as cotton and wool, and man-made synthetics, such as elastane and polyester.

Synthetic fabrics often add very functional elements to a garment. For example, adding a small percentage of elastane to a pair of cotton jeans will give them a slight stretch – making them less rigid and more comfortable to wear. Or, blending polyamide with wool can help the piece last longer, especially if it is a product designed to be worn repeatedly, like a winter coat.

We’re aware that blending natural and synthetic fibres makes them harder to break down and recycle into new fabrics. This is something we’re currently exploring with new partners and innovative technologies. However, synthetic fibres can add strength to a garment – meaning it can be worn more and live a longer life.


CASHMERE THAT CARES

By partnering with the Good Cashmere Standard, we’re able to make sure these precious fibres are sourced in the most responsible way.

CIRCULARITY, EXPLAINED

At COS, circularity means maximising our resources to minimise our waste in everything we create – whether it’s our iconic white shirt or the interiors of our stores.
