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. The last thing you want to think about when those suddenly dark clouds open up is what you’re wearing. That’s why our men’s and women’s running clothes feature no-chafe seams and shorts with odor-resisting Merino liners. Because when you’re comfortable, you can focus on what really matters.
