The Fox River Castile Light Merino Crew Liner is a ultra-lightweight merino wool crew liner socks with natural moisture control (men’s and women’s) knit by Fox River Mills in their Osage, Iowa mill. American-spun yarns, fine-gauge knit, and designs developed for US military, outdoor industry, and working wear deliver socks and gloves that handle real conditions — wet, cold, hot, miles on foot.
Use it for hiking, hunting, military and tactical wear, work boots, ranch and farm chores, and daily comfort. Fox River is the brand chosen by US Armed Forces, Bureau of Land Management, and outdoor pros who need socks that hold their shape, wick moisture, and survive the wash for years.
Fox River Mills has been knitting socks in Osage, Iowa since 1900 — over 120 years of family-owned American manufacturing. Every Fox River sock and glove is American-made.
