Expert Testimonials

PhD, Environmental Textile Engineer and Pioneer and Founder of SlowTech Labs

Sudeep Motupalli Rao

AIZOME is a potential  medicine you can wear. What is not there is the usual toxicological profile. But on the other hand, we have the benefits of natural dyes supported by a body of evidence.

Naturopathic Doctor, Wild Oak Medicine in Santa Rosa

Dr. Chris Holder

AIZOME is unique in their approach among all textile companies I know in their commitment to cradle to grave fully organic design down to even the dyeing process. They are harnessing the known healing power of plants, and deliberately omitting anything that we know can harm your health and the environment we all live in.

Prof. Lynda Grose

There are thousands of synthetic chemicals used in textile dyeing and all of them impact the workers, the environment and us. AIZOME is bringing a completely different way of thinking to textile coloring.

Transforming Textiles, Naturally

The textile industry has a petrochemical dependence. Awareness is growing, but so is greenwashing. According to research by the European Commission, 42% of sustainability claims in the textile industry are false or misleading, due largely to a lack of regulation or enforcement.

Our mission: prove that petrochemicals are unnecessary in textiles. We're embracing innovation, robust regulation, and consumer empowerment. From seed to sheet, we've partnered with organic and ethical manufacturing experts in some of the world's most directly impacted areas — India, China, Turkey — to revive a wiser, more holistic and transparent vision for textile creation, and a steadfast commitment to natural, plant ingredients.


Conventional: Repeated crop cultivation depletes soil, leading to heavy reliance on synthetic fertilizers and exploitative labor practices.

AIZOME: Advocating regenerative farming to rejuvenate soil for robust, healthy cotton growth and fair partnership with laborers.

Raw Material Harvesting

Conventional: Pervasive use of pesticides to boost crop yields, which can be detrimental to the environment and workers and can leave residuals in fabrics.

AIZOME: Commitment to regenerative organic cotton, free from harmful synthetic pesticides and fertilizers.

Fiber Processing

Conventional: Dependence on intense chemical processes to transform materials like wood or bamboo into yarn. Even conventional (and most organic) cotton is processed using detergents, caustic soda, and bleach.

AIZOME: Focused on unbleached organic and regenerative cotton, washed only with water and bioenzymes.


Conventional: Chemical treatments for enhanced strength and texture; bleaching for artificial whiteness and removing impurities.

AIZOME: Simple, clean processing with water and bio-enzymes and without synthetic chemicals, preserving the natural essence of the cotton.

Cutting and Sewing

Conventional: Often marred by opaque and exploitative labor practices.

AIZOME: Ethical collaboration with certified manufacturers, ensuring fair and safe working conditions and a living wage.

Accessories and Fastenings

Conventional: Often, clothing items come with accessories like polyester threads, plastic bands, zippers, and plastic buttons, which can compromise the integrity of eco-friendly claims.

AIZOME: We exclusively utilize 100% cotton threads for stitching and opt for natural (latex-free) rubber bands to provide elasticity.

Traditional Hand Dyeing

Conventional: Reliance on synthetic and even toxic dyes (see: azobenzene dyes) and chemical mordants.

AIZOME Artisan Line: Traditionally hand-dyed in japanese rivers using 100% real indigo dye

Distribution and Retail

Conventional: Utilization of environmentally harmful packaging and shipping materials.

AIZOME: Adoption of plastic-free, recyclable paper packaging, reducing environmental impact.
