Swiftwick Seven Olefin
The Seven Olefin has managed compression 7-inch cuff and 1-inch welt. Fits mid-calf.
Olefin produces a fast drying, lightweight sock with superb abrasion resistance and long-lasting durability. As a fiber, Olefin retains less than .01% of its weight in moisture and resists deterioration from chemicals and perspiration.
The combination of nylon and spandex with the Olefin fiber helps create a softer, more comfortable sock with incredible breathability for everyday wear.
