The REI CoolMax(R) EcoMade(TM) ultralight multisport quarter socks offer dependable performance and comfort for running, cycling, hiking and more. CoolMax EcoMade fabric offers the same moisture-wicking, quick-drying performance as regular CoolMax, yet is made of recycled PET. Nylon adds durability while spandex offers stretch and shape retention; the snug fit will remain, wash after wash. Noncushioned construction minimizes bulk; mesh-knit instep panels promote airflow and help move moisture away. Heels and toes are reinforced to supply increased longevity. Lin Toe(R) "no feel" seams preclude irritation and chafing along toes. *Discount will be applied when you check out. Offer not valid for sale-price items ending in $._3 or $._9.
