Care

Machine wash cold on normal cycle. Tumble dry low.

SUSTAINABILITY

Built on CiCLO® biodegradable fiber.

CiCLO® is built into our recycled synthetics to do two things: shed fewer microplastics in wear and wash, and biodegrade rather than linger. Independent testing shows CiCLO treated fibers biodegrade in under four years — so they don’t add to long-term microplastic pollution.

Certified by ECO PASSPORT by OEKO-TEX®.

Reviews

Great workout clothes

"I can finally lift weights or run without getting getting bogged down in sweat like I used to in a cotton t-shirt"

William L. (5/5)

The best socks I’ve ever owned!

"These are fantastic socks. Incredibly soft but they hold their shape well. Mine have nice longevity so far with very heavy use. I much prefer the simple blue stripes to a swoosh any day. You’ll want to buy multiples."

Mark G. (5/5)

Kimberlee M. (5/5)

Love the Thickness Of The Socks

"These are my go to socks for running. They are thin, but not too thin and so far I haven't torn any of them. The wear of the socks is really good. I highly recommend them as a person who reviews fitness products and loves to run and bike. In fact they are thin enough to also work as very good cycling socks."

Tom C. (5/5)
