Teko is committed to producing the highest quality performance socks while minimizing our environmental impact.

We approach sustainability as a balancing act. It's not possible to produce a product without using energy and natural resources, so it's our job to minimize our footprint at every stage. A major element of our commitment is constant research of new materials and production techniques to make that footprint smaller.

• Energy: Teko is 100% wind-powered at the office and the factory. Carbon offsets are purchased for staff travel.
• Materials: Our organic merino wool comes from Argentina from a group of farms that have been raising sheep organically for decades. Only non-motorized methods are used to herd the sheep. They are fed only organically-grown food and are not subjected to hormones, vaccinations, mulesing, or chemical drenches. Their grazing area is never sprayed with pesticides, herbicides or fertilizers. Strict water conservation methods are employed, as are protections against overgrazing. Organic merino wool is substantially more expensive than the non-organic alternative, but Teko believes the investment is worth it, both for consumers and the planet.
• Our recycled tekoPOLY fiber is made from 100% post-consumer waste, like plastic bottles.
• Chlorine-free processing: The chlorine-free process used to make tekoMERINO machine washable and shrink-proof, is the onlyBluesign® certifiedshrink-proofing process currently available for wool.
• Non-toxic dyes: No allergens, carcinogens, heavy metals or formaldehyde are used in our dyes. OekoTex 100 certification.
• Made in the USA: All of Teko's socks are knitted in North Carolina. This saves trans-Pacific shipping energy and pollutants. Well-regulated US facilities produce much lower levels of pollution.
• Sourcing: All materials except our merino wool are sourced within 200 miles of our factory in North Carolina, minimizing the impact of energy used in our shipping.
• Carbon Footprint: Teko's carbon offset credits are purchased from the Chicago Climate Exchange (CCX) to mitigate the carbon footprint created by shipping and staff travel.
• Minimal Packaging: We use chipboard, made from recycled materials like newspaper, paper bags, etc. The packaging is 100% recyclable.
• Durability: True sustainability means allowing for the whole product lifecycle, including disposal. Our socks are some of the most durable on the market, which means they need to be replaced less often.
• Outdoor Stewardship: Teko supports The Conservation Alliance in the US and The John Muir Trust in the UK, by donating a portion of our online sales revenue to these causes.

The actual cost of any transaction includes environmental and human elements. Teko pays fair prices for wool, labor and other materials, so that resources like land and water can be managed wisely, employees can enjoy better health and animals are treated humanely.
