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. Cut in a classic racerback silhouette with a long scooped hem, this tank is designed for comfort and repeat wears.

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 Tank through its paces in Boulder, CO and San Francisco. Marathoner Grace Kahura put it to the test over 5 x (5’ on 2’ off) on classic Boulder early spring day, with the sun shining and snow lingering on dirt roads. In San Francisco, Lyndsay took it to the track for 200s on a drizzly afternoon.
