The Swiftwick PERFORMANCE line of compression socks are made in America and designed to be the best socks you will ever wear - Guaranteed. To deliver top Performance Swiftwick use Olefin fibers to produce 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 antimicrobial fiber helps create a softer, more comfortable sock with incredible breathability for everyday wear.

Olefin, the only Nobel Prize-winning fiber, has a great story. Its production leaves very little waste; therefore, it has less environmental impact than most polymers and is easier to recycle. Olefin also has the lightest specific gravity of any other fabric. This is why Swiftwick socks will float in water.
