Where the fibers go after every wash
1
Every wash
Synthetic clothes shed thousands of plastic fibers. Washing machines have no filter to stop them.
2
Into the water
Treatment plants can't catch them all. The rest flows into rivers, lakes and the sea.
3
Into the fish
1 in 4 market fish tested had man-made debris inside. Most of it was fibers.
4
Onto a plate
Those fish were sold for someone's dinner.
Ours are mostly organic Pima cotton. The nylon we add sheds far less.

What touches your skin 16 hours a day
Most socks are blended with polyester and nylon: plastic against your skin all day, shedding microplastics with every wash.
Ours are mostly organic Peruvian Pima cotton, grown without synthetic pesticides. Lab-tested: 0 PFAS, 0 BPA detected.
The nylon we add for durability is continuous filament, so it sheds far less. When they wear out, they break down in years, not centuries.

Years a conventional sock can take to break down.

What customers say
⭐⭐⭐⭐⭐
I never thought about microplastics in my socks
"I'd been trying to reduce plastic in my everyday life, but honestly never thought about what was in my socks. Once I started reading about synthetic fibers, I checked the labels on the socks I already owned. Almost all polyester. REVERT caught my attention because they're mostly organic Pima cotton. I ordered a pack and was surprised by how soft and comfortable they were. It feels good knowing more about what I'm wearing every day."
— Daniel R., Seattle, WA
⭐⭐⭐⭐⭐
The lab testing is what convinced me
"I've seen plenty of brands claim their products are natural or clean, but it's hard to know what to believe. What caught my attention with REVERT was that they actually tested their finished socks for PFAS and BPA. Seeing zero detected made me comfortable giving them a try. They're also incredibly soft and feel like a premium product. I wish more clothing brands were this transparent about what goes into their products."
— Jorge B., Austin, TX
⭐⭐⭐⭐⭐
I thought natural cotton socks wouldn't last
"I've always preferred cotton, but the cotton socks I've bought before tended to stretch out or wear thin pretty quickly. I was hesitant to spend more on REVERT for that reason. What convinced me was the combination of Pima cotton and reinforced construction. So far, they've held their shape through regular washing and feel great throughout the day. It's nice finding socks that combine better materials with everyday comfort."
— Lisa F., Denver, CO
