Care - Machine wash cold on normal cycle. Tumble dry low.
Tested, Tried & True: Independently lab-tested free from BPA and PFAS. Most brands won’t claim this — because they can’t.
Premium Performance Yarns: Our high-quality, fully traceable yarns are sourced through sustainable partners, including a family-owned mill in the U.S. These materials meet rigorous chemical safety standards and are independently verified for harmful substances through certifications such as STANDARD 100 and ECO PASSPORT by OEKO-TEX®.
Biodegradable Innovation: We use CiCLO®-enabled yarns—certified by ECO PASSPORT by OEKO-TEX®—that allow yarns like nylon and polyester to biodegrade in the environment more like natural fibers. Instead of persisting for centuries, these yarns break down in a matter of years when exposed to landfill or ocean conditions.
Recycled materials, minimal waste: Our commitment to protecting the planet starts with sustainable fibers and yarns. We use synthetic yarns made from recycled plastic bottles which helps remove ocean plastic and repurpose unused short fiber from the yarn spinning process. Our sports bras are designed to minimize waste and environmental impact—without compromising on performance or comfort.

"Super comfortable and great quality. All day comfort and support. These easily became my go-to sock!"
"Would definitely recommend to purchase. Comfortable with great quality and fit true to size."
"These socks are so wonderful I had to buy more for my husband! Absolute comfort, won’t slip, great compression, won’t loosen over time, and clearly high quality material. I also ended up getting the no show socks too! Thank you for the great customer service as well!"
"white socks great - colored socks run small"
"They are super comfy, don’t fall down and are slightly cushy in a good way"
"I've been a fan of Definite Articles for over a year. Love their socks and my wife is a big fan of their leggings but bought my 12-year-old a pair of their joggers (women’s small fit great). She opened as one of her holiday gifts and wore the next day. Said they were the "softest, best fitting pair she ever had" and was even happier when i shared how they are helping the environment. You've got another fan for life. Can't wait to try some of your other products. Anyone looking for great socks and athleisure wear should check these guys out. You won't be disappointed."
"Great fit. They don't slip down when you run. And I bought the XL size (I'm a men's 12) and there was still room in them. Not bulky."
"I've never treated myself to nice socks. Usually, I would always by whatever was cheapest. I decided to care for my body and my planet by getting something comfortable, environmentally friendly, and made without chemicals. These socks are super comfy! I can leave them on my feet all day and the fabric is the perfect thickness."
"Never received."
"Good"
