You will love how these feel on, regardless of hiking or hanging out. Made from soft, warm, natural alpaca and other microfibers - 100% wool free, hypoallergenic. Has a "ragg wool" type of feel and texture. Wear them with your favorite sandals, shoes, boots, Columbia or Merrell's, for cozy dry happy feet! Keeps feet warm, even when wet. Stays soft and odor free even with repeated wearings between washings. This means less washing and sweeter smelling feet, socks and shoes. Unlike wool which holds moisture, Alpaca doesn't absorb, rather it lets the body heat vaporize moisture, wicking it away from feet. Alpaca keeps feet comfortable in warm climates and cozy in cold climates, a perfect all-season property keeping feet dry and safe. Easy to wash - Machine wash cold, cool air tumble dry or air dry. Makes a great gift.
