OUR PREFERRED
MATERIALS
FRAMEWORK
We believe that the materials we choose define not only our products but also our impact on the planet and the people who make them. That’s why we’ve developed Our Preferred Materials Framework – a clear, practical framework to help us make smarter material choices that are grounded in industry research, aligned with leading standards, and designed to evolve.
Our Preferred Materials Framework
Our Preferred Materials Framework is a dynamic tool to help guide responsible sourcing, ensuring we prioritize fibers that have lower environmental impact, credible certifications, traceability, assurance, and responsible chemical management. The framework categorizes fibers into three levels: Best, Better and Basic.

Best Fibers
The leading choices for sustainability, backed by credible certifications, supply chain traceability, third-party audits, and responsible chemical management. These fibers align with leading industry initiatives such as Textile Exchange and Canopy.

Better Fibers
Those that demonstrate improved environmental and/or social practices compared to conventional alternatives.

Basic Fibers
These conventional fibers represent the start of the framework and serve as a baseline for improvement.

To stay aligned with the latest developments in preferred materials, we continuously update our Preferred Materials Framework in response to evolving industry standards, certifications, and scientific advancements, including Textile Exchange’s Fiber & Materials Matrix, CanopyStyle’s Hot Button Report, Cotton Incorporated, and other trusted sustainability resources. This adaptive approach allows us to push for progress over perfection – supporting more responsible material choices while recognizing the complexities of systemic change. It also keeps us on track to meet our 2030 goals: using 90% Better or Best fibers across all our materials and using 100% Better or Best cotton. By driving industry-wide transformation and providing greater transparency, we aim to empower our teams, partners and consumers to make more informed choices.
Prioritizing Traceability
Creating more responsible products starts with knowing exactly where our materials come from, which is why we’ve set an ambitious goal to attain 100% disclosure of Tier 1 and Tier 2 suppliers. While we are working towards this goal, our U.S. cotton sourcing stands as a strong example of our progress in action.
In 2024, 89% of all our cotton — around 180 million pounds — used Better or Best fibers, much of it from U.S. growers. We choose U.S. cotton not only for its quality, but because it’s grown using leading practices for land and water use, with fewer pesticides and under some of the world’s most rigorous labor standards. Thanks to a bale identification system, we’re able to trace this cotton down to the gin level – giving us rare visibility into how it’s grown and who produces it. This level of traceability allows us to make better sourcing decisions and is part of our efforts to create products that are grounded in transparency, responsibility, and less impactful for both people and planet.
For more information about the traceability of our cotton, see our U.S. yarn and cotton gins, which can be found on our Traceability page.
