Merino Wool Benefits
Smartwool combines the function of wool's natural strong suits with their one-of-a-kind knitting technology to give you:
- Temperature control, so you're warm when it's cold and cool when it's warm.
- No Stink, because Smartwool's Merino wool keeps your feet dry and is inhospitable to bacteria.
- Easy care, which means that you can machine wash and dry.
- Ultimate breathability.
