Inspired after a week long hike (not wearing alpaca socks), these Base Camp Alpaca Socks are designed to promote warmth and comfort while outside. Keeping feet comfortable is the first and most important step to staying warm – maximizing enjoyment of the day! This heavy crew offers warmth, softness and protection so that the wearer has a better advantage, no matter what the day calls for! These base camp alpaca socks will keep feet warm even if they get wet, thanks to the unique thermal properties they possess. After repeated wear, cotton and wool socks get stiff and smelly. Alpaca socks do not absorb foot odor and remain soft and odor free, even with repeated wear between washings. We have gone one step farther and added an extra reinforced heel and toe, as well as arch support for the most comfortable fit. Our designers know what is needed in performance socks and we have carefully added the necessary elements to offer a truly wonderful sock, resulting in the best experience for the wearer. Made from soft, warm, natural alpaca and other microfibers, free from wool; these socks are hypoallergenic and allow for the most thermally comfortable feet, regardless of working hard or relaxing hard! Our Warrior Base Camp socks are made from a thick flat knit, used throughout the balance of the sock, to ensure optimal fit.Designed to keep feet warm regarless of conditions, this sock has arch support and an extra reinforced toe and heel for added durability.
