Merrell Premium Wool Trail Low Cut Sock
Lower risk but Merrell's silence on water-repellent coating treatment leaves uncertainty.
Wool naturally resists water and needs no PFAS-based finishes, but Merrell doesn't publicly confirm whether any fluorinated coating was applied. No testing available to verify.
Still want this one anyway? Check the price on Amazon. We’d swap it.
