Why Smartwool? All Smartwool products benefit from harnessing wool's naturally strong properties with their one-of-a-kind knitted technologies. As a result Smartwool gives you:

• Temperature control, so you’re warm when it's cold, and cool when it's warm.
• No smell, because Merino wool keeps your body dry and inhospitable to bacteria.
• Easy care, all Smartwool products can be machine washed & dried.
• Outstanding breathability, so your body doesn’t have to work as hard to maintain its core body temperature during activity
