MEET OUR SUPPLIERS
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 range from organic to recycled, responsible to regenerative.
So far in 2024, xx% 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.
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.
REGENERATIVE OR ORGANIC
Regenerative farming practices improve soil matter and microbiology to enhance the soil's capability to capture carbon..
Organic materials are grown from organic seeds that 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.
SO FAR IN 2024: XX%
*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 AND 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.

RECYCLED AND REPURPOSED
We believe every piece should have a long lifespan. To make sure the materials in our collections meet our exacting standards, we use conventional fabrics such 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. As part of our work with the H&M group, we are also pleased to announce our commitment to promoting responsible leather manufacturing practices worldwide as a member of the Leather Working Group (LWG).

NATURAL VS SYNTHETIC
Most of the synthetics we use have been converted into recycled alternatives and we are making the transition to organic silk as well. As part of our work with the H&M group, we are also pleased to announce our commitment to promoting responsible leather manufacturing practices worldwide as a member of the Leather Working Group (LWG).
Synthetic fabrics often add very functional elements to a garment. For example, adding a small percentage of elastane to 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’s 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.
MEASURING SUCCESS
We believe better choices come from thinking about more than the materials we use. If we are to reach our goal of 100% sustainably sourced materials by 2025, we need to use the right tools to measure our progress too. That’s why we use the Material Environmental Benchmark set by the H&M Group. This framework helps us score each fabric we use based on its environmental impact. Find out more about our Material Ethics and the other steps we’re taking here.
