Preferred Materials
Why do we have Preferred Materials?
Having a defined list of preferred materials helps us set clear standards for more responsible sourcing.
Our Preferred Materials framework establishes these standards by guiding material choices toward lower environmental impact than conventional alternatives, while also prioritising recycled content, repairability, and recyclability, and supporting regenerative agricultural practices where possible.
To make these standards actionable, we have categorised our materials into four impact-based groups: Leading Choice, Preferred, Limited Use, and Not Accepted. Each category reflects environmental, social, and performance considerations, helping to guide material selection and support more responsible choices across our collections.
Our material standards are informed by industry best practices, such as the Textile Exchange's Fibre and Materials Matrix. Alongside this, we continue to champion the development of innovative materials and technologies that reduce impact and, where possible, actively support the health of our oceans.
To uphold the integrity of our materials and processes, our framework incorporates material-specific certifications that validate our environmental and social sourcing practices and support recognised external standards.
Maintaining our preferred material standards keeps us focused on long-term progress, while remaining clear-eyed about the sourcing constraints we face, including material availability, cost considerations, and minimum order quantities (MOQs).
As new science emerges, our understanding deepens, and innovations in materials and technologies continue to evolve, we will regularly review and update our material standards. This ensures we remain responsive to new regulatory requirements, reflect our learning as a team, and continue to evolve as a business committed to progress.
Our 2025 Collection
92% of the materials, by weight, in our 2025 collection met our ‘Preferred’ standard or higher*. Another 5% were ‘Limited Use’ and only 3% didn’t meet our standards.
