Versatility Rules

We launched our Harrier tops in 2014 and they quickly became the training staple Tracksmith employees swear by. Lightweight, soft, moisture-wicking and odor-resistant, all thanks to the natural properties of Merino wool.


94% Merino Wool / 6% Elastane
Machine Wash Cool with Like Colors
Delicate Cycle
Hang Dry

Bet On Merino

When it comes to performance fabrics, merino wool is a freak of nature. A natural, surprisingly soft fiber that regulates temperature, even when drenched with sweat, it’s practically impervious to odor. We love merino in spring - it’s the ideal material to beat the chill of early mornings and transition through the warmth after sunrise.

Hope Springs

There’s an old New England springtime saying, “It won't be warm till the snow gets off the mountain, and the snow won't get off the mountain till it gets warm." The days are longer, but not yet warm. Snow lingers on the road, but the sun shines brighter. Our legs feel lighter, but not yet fast. Still, we know the speed will come. Spring is just the starting point.

Boulder To SF

This spring, we put the Harrier Tee through its paces in Boulder, CO and San Francisco. Marathoner Mick Iacofano wore the Harrier for a 13 mile long run on the infamous Magnolia Drive, on a classic spring day that started cold and ended on the warmer side. In San Francisco, middle-distance runner Taylor Gilland put in some windy miles on Mt.Tam.
