STAY WARM: Merino wool over-the-calf socks are ideal year-round, including winter, because the fabric is excellent at thermal regulation by keeping you warm on cold days and cooler in warm weather. NATURALLY WICKING: High-quality wool fiber draws sweat away from the skin, absorbing and releasing 10X the moisture of synthetic fibers. ODOR-RESISTANT: The extra-fine fibers of Merino wool offer no-shrink layering between the skin and boots without itch or odor, making them a smart choice for ski trips, outdoor work, and athletic activities. QUALITY AND COMFORT: These are durable mid-calf height socks with reinforced midfoot, heel, and toe support, made in the USA. SIMMS GUARANTEE: If your Simms product fails due to a defect in workmanship or materials, let us know to repair or replace your gear and get you back in action as soon as possible.
