Smartwool mountain scene


The Smartwool story started on a rugged ski slope with the belief that toes didn't have to be cold.  


One simple pair of Merino socks challenged the conventional wisdom and forever changed the way outdoor enthusiasts looked at their socks, clothing and accessories. We have taken outdoor and everyday apparel and elevated them with Merino, giving you comfort, temperature regulation and anti-stink technology, no matter where the trail may take you.  

Smartwool Merino 250 Base Layers

Smartwool Merino 250 base layers are 100% Merino wool, to take you from the backcountry to apre in style.


Every epic adventure starts with a solid base. And when you start with Smartwool® 100% Merino 250 as your next-to-skin layer, you've got a warm, dry foundation for a wide range of conditions. Merino 250 is incredibly soft, naturally thermoregulating, odor-resistant, and machine washable. It's the ultimate in comfort whether you're backcountry-bound or just relaxing around town.
