Crafted from a premium blend of 50% Merino wool, 30% Acrylic (anti-pilling), 18% Nylon, and 2% Spandex, these mid-calf socks offer natural temperature regulation, moisture-wicking, and odor resistance. The Merino wool provides warmth in winter and breathability in summer, while the added synthetic fibers ensure durability, flexibility, and a snug fit. Thin enough for year-round wear, they’re as perfect for summer hikes as they are for cozy winter nights.
