The Smartwool Promise

We stand behind everything we make. We promise to make our products with incredible attention to comfort, fit, and durability—because we want you to love our gear as much as we do.

And we want our products to be able to support all of your adventures, from exploring new cities to summiting new mountains. So if, for any reason, you aren’t completely happy with your Smartwool® gear within two years of purchasing, we’ll take it back. No problem.
