These are premium, fairly-traded, Peruvian pima cotton socks. All styles of Pima socks are custom Pokoloko designs. 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. These socks are washed with aloe vera for added softness, are hypoallergenic for those with sensitive skin, and breathable and moisture-wicking for those active sock-lovers.
