Made in the USA with US-grown alpaca fiber, milled through the New England Alpaca Fiber Pool, which collects fiber from American alpaca farms — including our own — and produces alpaca products at commercial scale. A lightweight hiker sock designed for you to forget it's even on while you march through the wilderness or dance the night away. Terry loop construction along the sole of the foot provides cushion, padding, and comfort where it's most needed. The ribbed knit along the top of the foot and up the calf allows for increased breathability and moisture wicking. Dense knit construction along with arch and ankle support bands keep the sock tightly in place throughout the day without bunching, slipping, or blisters on the trail. U.S. alpaca will keep its temperature-regulating properties both when dry or wet. It's also naturally antimicrobial, bacteria- and odor-resistant, making it a perfect fit for your next long outdoor adventure. If you love U.S. alpaca socks and have wished for a lightweight, less bulky option — particularly in warmer climates and months — this is the sock for you!
