Copper-ion yarn engineered into the knit rather than applied as a finish. Positioned on freshness and all-day wear.

FOB from 200 pairs Sampling in 7–10 days Documentation package included
Every style is built on the same graduated 15–20 mmHg platform, so your size charts, packaging and claims stay consistent across the range. Choose the programme that matches your shelf, or mix across all four.

Tell us your style, colour and quantity — we quote from a single manufacturing partner we work with directly, not from a reseller catalogue.
Start a private-label enquiryMost wholesale compression suppliers send you a price and a photo. We send you the documents that let you put a number on your own packaging.
Every style ships with a third-party graduated compression test report covering ankle, calf and upper zones. Print the mmHg rating on your listing with a document behind it — not a supplier's assurance over WeChat.
Our manufacturing partner holds a copper-ion yarn patent. The yarn is engineered into the knit, not sprayed on as a post-treatment — which is the difference between a programme and a commodity sock.
Wide-calf grading to 5XL, graded on calf circumference rather than an upsized shoe chart. Extended sizes remain one of the least contested categories in US compression retail.
We supply 15–20 mmHg as everyday legwear and make no treatment, cure or prevention claims. Your marketing stays inside a defensible line, and so does ours.
COTNOOK is the trading brand of Xuzhou Mianxiaowo E-Commerce Co., Ltd. Our legwear is knitted by Zhuji Wanyu Knitting Co., Ltd. in Zhuji, Zhejiang — China's sock-making heartland — and shipped FOB Ningbo.
We are a supplier and exporter, not a manufacturer. That distinction is worth stating plainly: it means our documentation, lead times and specifications all trace back to one facility we have direct access to, rather than a broker's spreadsheet.
No hidden minimums beyond what is listed here. If something below does not fit your programme, tell us — most of it is negotiable at volume.
