These socks are so wonderful I had to buy the six pack! Absolute comfort, won’t slip, great compression, won’t loosen over time, and clearly high quality material. Thank you for the great customer service as well!

The Founder Story

Every Product Tested

Articles made to last, just not forever.

Thanks to CiCLO® technology, our performance fabric biodegrades like wool or cotton - in under four years - dramatically reducing long-term microplastic pollution without impacting performance or durability.
Sustainabilty

We are planet lovers

Microplastics are tiny fibers that shed from performance fabrics when you wash and wear them. Microplastics are everywhere: oceans, drinking water, even inside our bodies.

That's why we use CiCLO - it helps our performance fabric break down like cotton or wool, naturally, when discarded. Still high-performance, just less permanent.

Sustainabilty

Certified B-Corp

We measure success by how well we serve our profits and our planet—both matter. That’s why we became a Certified B Corp, joining a movement of businesses committed to doing good.

To further our mission, we donate 2% of our annual revenue to nonprofits dedicated to creating a healthier, happier world.

Sustainabilty

We plant trees

Definite Articles partners with One Tree Planted to plant a tree for every order. Together, we're helping restore forests damaged by wildfires and deforestation—one order at a time.
