This is a pack of 2, custom designed mixed-and-matched Peruvian Pima cotton socks.  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. Materials 80% pima cotton, 15% nylon, 5% spandex Sizing S/M: wmns 5-9 mens: 4-8.5  L/XL: wmns: 9.5-12 mens: 9-14 Origin Peru
