ATLANTA - eTradeWire -- Updated Copper Content for Accuracy

Previously, we stated that COES COPPERFINGER socks contained 45% copper-infused fiber. However, after further testing and verification, we have confirmed that the actual copper-modified polyester fiber content is 33.2%. We sincerely apologize for any confusion and assure our customers that this correction reflects our commitment to honest and accurate product representation.

Material Composition Breakdown

COES COPPERFINGER socks are crafted with a carefully balanced blend of fibers to optimize performance, comfort, and durability:

• 37.1% Polyester : A synthetic fiber known for its moisture resistance, strength, and durability.
• 33.2% Copper-Modified Polyester Fiber: A specialized polyester infused with copper for antimicrobial and odor-resistant properties.
• 27.9% Cotton : A natural fiber providing breathability and comfort for extended wear.
• 1.8% Elastane : Also known as spandex, this component adds stretch and elasticity for a secure, flexible fit.

Additionally, extractable heavy metal testing confirms a copper content of 5090 mg/kg, reinforcing the strong antimicrobial properties of our socks. This copper concentration actively helps reduce odor, inhibit bacterial growth, and enhance hygiene.

Does This Impact Performance?

No—COES COPPERFINGER socks still deliver the same high-quality benefits that our customers love. Research has shown that copper content beyond a certain threshold does not necessarily improve antimicrobial effectiveness. With 33.2% copper-modified polyester, we maintain the optimal balance of functionality, durability, and comfort.
