The SmartWool Advocacy Fund

The SmartWool General Advocacy Fund supports non-profit organizations that get kids into the outdoors while educating them about environmental stewardship. Since 2005, more than a million dollars has been raised and granted through the smartwool.com e-commerce outlet, which has provided 100% of the SmartWool Advocacy Funds since its inception. Through your online purchases, you have helped us donate more than a million dollars to organizations like The Womens Wilderness Institute and Outdoor Outreach, among many others.

SmartWool PhD Socks

Whatever your trail, the PhD Outdoor sock collection is made for mileage. Bi-elastic construction for focused fit, flex, and recovery create a sock that stays exactly where you need it to be. And our patented ReliaWool™ technology provides superior durability for socks that’ll go more miles than your shoes.

NTS Micro 150 Shirt

It’s light, it’s versatile, it packs up small. This do-everything Merino tee is ready for everything you throw at it and more. Merino naturally regulates body temperature, moisture, and odor so you can wear it as a baselayer or as a stand-alone piece in warmer temps.
