SmartWool has grown from a couple of guys in New England hawking ski socks to a full line of some of the best base layers on the market, their breadwinner being their industry-leading socks. A wide variety of socks are all engineered specifically for activities like walking, hiking, cycling, wearing high heels, skiing or snowboarding. Other items like the Synergy Jacket is perfect as a layer or stand alone and the Microweight Boxer Brief's "up and out" fly design and flatlock seam construction eliminates chafing.

A far cry from the scratchy wool of yesteryear, SmartWool comes from New Zealand's specially bred free range Merino sheep. This particular fiber is 90% Keratin, a protein resistant to chemical and bacterial attack, naturally flame retardant, and is 1/3 to 1/10 the thickness of human hair. A renewable natural resource, SmartWool is light and airy providing non-itchy cushion and insulation, making it effective in all conditions whether walking around in the rain or shine. It wicks away moisture and sweat while maintaining a comfortable temperature in heat or cold, keeping you dry, warm and odorless—unlike the stink that comes from wearing synthetics.

Commited to leaving a smaller footprint, SmartWool donates ten percent of every web order to the SmartPrint Advocacy fund which supports select non-profit organizations. SmartWool also ensures sustainable business practices by working closely with their New Zealand wool growers to guarantee minimum price levels for the wool.
