Trail runners in Smartwool wool running clothes

 

Merino Wool Running Clothes

 

Made for the road, trail, and every scramble in between.

Over muddy switchbacks or under redwood canopies, wherever the trail leads, our Merino running clothes are happy to follow. Like you, they live for adventure and can’t wait for the next trail. But when a mile 5-mile loop turns into a 10-mile detour, the last thing you want to think is what you’re wearing. That’s why our wool running apparel features no-chafe seams and shorts with odor-resisting Merino liners. Because when you’re comfortable, you can focus on what really matters. Like finding the car.

Smartwool PhD® Thermal Body Mapping Technology: Understanding the body in motion.

 

Body mapping shows that sweat isn’t gender neutral. And comfort creates efficiency. That’s why we address men’s and women’s bodies differently, zone by zone. Body mapping technology allows us to put the right amount of breathability and warmth where you need it most. That means details like mesh panels on Smartwool® PhD® tops where men sweat the most and women’s-specific breathability zones on PhD® socks. It all adds up to serious comfort, making you more efficient over the long haul.
