Materials Matrix 2025
Below is a breakdown of how we grade our fibres for decision making. We use this as a tool for internal decision making, target setting, and reporting by weight for continual improvement. We never use this methodology for product-level claims.
Materials Grading Matrix
The matrix categorizes fibres into five levels: Best, Great, Good, Okay, and Restricted, based on their suitability and impact.
Best: We are obsessed with
- Deadstock
- Regenerative Cotton
- Recycled Cotton
- European Flax Linen™
- Organic Linen
- Organic Hemp
- LENZING™ ECOVERO™ Viscose
- TENCEL™ Lyocell
- Naia™ and Naia™ Renew
- Birla Excel
- Birla Livaeco
- TENCEL™ x REFIBRA™ Lyocell
- Birla Reviva
- Regenerated MMCF
- Peace/Ahimsa Silk
- Regenerative Wool
- Recycled Wool
- Recycled Cashmere
- Recycled Alpaca
- Next Gen Leather Alternatives
- Textile-to-Textile Polymers
- Next Gen Polymers (T400, B210)
Great: We love using
- Organic Cotton
- Fairtrade Cotton
- Conventional Linen
- Conventional Hemp
- TENCEL™ Modal

Good: We prefer using over conventional materials
- Transitional Cotton
- Certified Viscose (Canopy)
- Leather from Certified Tanneries
- Veg-tanned Leather
- Conventional Alpaca Wool
- Recycled Elastane

Restricted: We only use in very small quantities if necessary
- Conventional Cotton
- BCI Cotton
- Conventional Leather
- Conventional Viscose
- Conventional Modal

Material Categories Legend:
- [Plant Fibres Indicator] Plant Fibres
- [Animal Fibres Indicator] Animal Fibres
- [Deadstock Indicator] Deadstock
- [Synthetic Fibres Indicator] Synthetic Fibres
- [Wood based Fibres Indicator] Wood based Fibres
- [Recycled Feedstock Indicator] Recycled Feedstock
We aim to source majority of materials from these categories.
