The Complete Guide to Sustainable and Ethical T-Shirts

We all need T-shirts. Yet, not every T-shirt is made with care for the planet or its workers.

That’s why I’ve compiled a list of 20+ brands, each rated on ethics and sustainability. These ratings reflect factors like fair wages, organic or recycled fabrics, responsible water use, and transparent supply chains.

What do we mean by a “sustainable T-shirt”?

It’s a shirt that respects the environment from the start. That can mean using organic cotton, recycled materials, or zero-waste packaging. It also involves fair labor conditions, so every person involved is paid and treated well.

Patagonia

Shop Patagonia.

Patagonia uses recycled polyester, nylon, wool, and organic cotton. Its products emphasize durability and repair, with a transparent supplier list and Fair Trade Certified factories. Some facilities pay living wages.

Patagonia runs the Worn Wear program to extend product life. The “Don’t Buy This Jacket” campaign reflects its anti-consumerism stance. As a B Corp, it follows Fair Trade USA and FLA codes but isn’t fully sustainable yet, aiming to expand living wages across its supply chain.

Everlane

Shop Everlane.

Everlane uses some organic cotton and recycled fibers, with classic designs that aim to reduce waste. It publishes certain factory locations and photos but doesn’t provide full audits or living wage verification. Although it promotes “radical transparency,” there’s limited proof of worker empowerment.

The brand set science-based CO2 reduction goals, eliminated some toxic chemicals, and launched an eco-denim line. Critics point out partial transparency, a risk of greenwashing, and an anti-union controversy in 2020.

Reformation

Shop Reformation.

Reformation sources TENCEL™, recycled fibers, and organic cotton, plus Bluesign® and OEKO-TEX certified fabrics. It avoids virgin viscose from endangered forests and traces most of its supply chain, paying some workers a living wage. Fair Trade sewing, a Los Angeles factory, and audited overseas partners reinforce its labor standards.

The brand faced allegations of racism in 2020, prompting leadership changes. It plans to expand living wages, phase out leather, and follows the Five Freedoms animal policy

Pact

Shop Pact.

Pact uses 100% GOTS organic cotton for all tees, with no toxic pesticides. It partners with Fair Trade Certified factories in India, ensuring safe conditions and supporting small cotton farmers. Shipping is carbon-offset, packaging is plastic-free, and it offers textile recycling for old clothes.

As a Certified B Corp with strong third-party certifications, it faces no major red flags and backs every claim with verifiable standards.

MATE the Label

Shop MATE the Label.

MATE the Label sources GOTS organic cotton, linen, and TENCEL™, relying on non-toxic, low-impact dyes. Everything is made locally in Los Angeles under fair conditions, with a women-led workforce. It’s Climate Neutral Certified, donates 1% of sales, and keeps a low transport footprint by producing near home.

A Certified B Corp with transparent practices, it has no notable red flags, though prices run higher due to its ethical production.

Quince

Shop Quince.

Quince mixes organic fabrics like cotton and linen with conventional cashmere, silk, and leather. It claims “responsibly-made” but provides little detail on factory conditions or living wages, and it’s not Fair Trade certified.

The brand uses minimal packaging and some certified down, but its emissions strategy is unclear. With no major sustainability or labor certifications, Quince risks greenwashing by marketing “sustainable luxury” at low prices.

For Days

Shop For Days.

For Days uses 100% GOTS organic cotton and designs tees for closed-loop recycling. It offers a Take Back Bag that turns old clothes into new yarn, cutting waste and promoting a circular model. Some production occurs in the U.S., but there’s limited detail on overseas factories.

While carbon-neutral shipping and plastic-free packaging are plusses, the brand focuses more on end-of-life recycling than transparent labor practices. Good On You rates it “Good,” though some doubt whether all returns are truly recycled.

Harvest & Mill

Shop Harvest & Mill.

Harvest & Mill sources organic cotton from California and Texas, including undyed, unbleached options. The entire process stays in the U.S., from farm to sewing – which ensures fair pay under local law and slashes transport emissions. It also uses compostable packaging and minimal water, since no dyeing is involved.

As a small, family-owned operation, it’s highly transparent but not a B Corp. Limited sizing is its main challenge, not ethics.

Classic T-Shirt Co.

Shop Classic T-Shirt Co.

Classic T-Shirt Co. uses 100% GOTS organic cotton, with U.S. production in California. Its thick, durable fabric and small-batch approach reduce waste. Fair labor is ensured by American standards, and there’s no evidence of worker issues.

Packaging is plastic-free and recycled, and the brand partners with 1% for the Planet. While prices run high, this reflects actual production costs rather than greenwashing.

tentree

Shop tentree.

tentree sources organic cotton, TENCEL, hemp, and recycled polyester, planting ten trees for each product. Some factories align with Fair Trade or Fair Wear standards, and as a B Corp, the brand focuses on ethical labor and carbon neutrality.

Shop ARMEDANGELS.

ARMEDANGELS avoids conventional fabrics, opting for GOTS organic cotton, TENCEL, recycled fibers, and non-mulesed wool. It holds Fair Wear Foundation Leader status, invests in living wages, and regularly audits facilities.

Kowtow

Shop Kowtow.

Kowtow sources 100% Fairtrade organic cotton for tees, plus some TENCEL, linen, and ZQ merino. It discloses a full supplier map and follows a rigorous Code of Conduct. Regenerative farming, a repair program, and compostable packaging keep its carbon footprint down.

Shop Yes Friends.

Yes Friends makes T-shirts with GOTS organic, Fairtrade cotton in a solar-powered, SA8000-audited factory in Bangladesh. Workers earn about 50% above the minimum wage, with a goal to reach a true living wage. The brand discloses its cost breakdown, keeps margins low, and avoids cutting corners on ethics.

Packaging is plastic-free, and the solar factory cuts carbon emissions. With “Great” ratings and proof that a £7.99 tee can be ethical, Yes Friends shows radical transparency to dispel greenwashing doubts.
