COS collections are built on a foundation of quality and lasting design. We celebrate noble fibres and tactility, and every cloth is selected for its character, yarn count, fibre length and finish. 

Our in-house design team prioritise natural fibres in our collections, such as cashmere, cotton, wool and linen. We also focus on sourcing quality materials that include organic, recycled and fibres certified by Textile Exchange’s animal-welfare standards, who independently certify animal welfare and land-management practices.
