The Fox River Castile Merino Wool Liner Sock is an ultralight Merino wool crew sock for solo wear or layering under heavier socks. Merino wool naturally wicks moisture, regulates temperature, and resists odor. The 65% Merino / 34% nylon / 1% spandex blend is itch-free and durable. Reinforced heel and toe extend sock life. Flat toe seam eliminates pressure points. Made in the USA.

Why it works:

Merino wool is the best natural fiber for moisture management and odor resistance — it wicks moisture, regulates temperature across a wide range of conditions, and resists odor buildup far better than synthetic fibers. The nylon reinforcement at heel and toe addresses Merino's one weakness — abrasion resistance — extending the life of the sock significantly. The itch-free construction makes it comfortable against bare skin, unlike coarser wool blends.

Ideal for: Hikers, backpackers, hunters, and travelers who want a natural fiber liner sock with moisture management and odor resistance. See also the polypropylene Alturas liner (FOX112, FOX132) for a synthetic moisture-wicking option.
