At Marree, sustainability isn't a marketing claim — it's the operating principle. Every design decision, from fiber sourcing to packaging, is made with the intention of reducing harm and keeping quality high. Here's how we work.

1. Organic Fabrics

We use GOTS-certified organic cotton, organic linen, and OEKO-TEX certified Mulberry silk. GOTS certification ensures no harmful chemicals, synthetic fertilizers, or toxins enter the supply chain — or the soil. Natural fibers are better for your skin and better for the planet.

2. Water Conservation

Our pieces are made in small batches which means minimal water use compared to industrial production. We reuse natural dye vats until they're fully exhausted, and we use no toxic chemicals in our dyeing process.

3. Natural Dyes — No Synthetics

Every Marree piece is dyed with either OEKO-TEX dyes or authentic botanical pigments: indigo, pomegranate, madder root, marigold, walnut, and onion skins. We never use synthetic fabrics, which means no microplastics and no chemical runoff.

4. Upcycled & Recycled Materials

Fabric scraps and remnants are saved and repurposed into jackets and tote bags rather than going to landfill. Our packaging is made from recycled materials and is often compostable. Nothing useful gets thrown away.

5. Slow Fashion & Garment Longevity

We make pieces meant to last — and to be worn, repaired, and kept. We encourage our customers to care for their garments rather than replace them. A well-made piece worn for ten years is the most sustainable fashion choice there is.

6. Hyper-Local Supply Chain

Our supply chain is deliberately local to the San Francisco Bay Area, keeping carbon emissions per garment as low as possible and reinvesting in our regional economy. Jenny sketches, dyes, and finishes every piece in her Berkeley, CA studio.

7. Our Commitments

Marree is a Fibershed Supporter and a member of the Sustainable Fashion Alliance. We're committed to fair wages, supply chain transparency, and a fashion industry that prioritizes people and the planet over volume and speed.
