This is a pack of 2, custom designed, sporty and cozy mixed-and-matched Peruvian Pima cotton socks to keep your feet warm and comfortable.  Peruvian pima cotton is hand-harvested, which means the production process has a much-reduced impact on the environment compared to a machine-based harvesting production process. It is hypoallergenic for those with sensitive skin, and it's breathable and moisture-wicking for those active sock-lovers.
