Warmth when wet and no stink!

I’m in the Pacific Northwest, so it’s common for me to start a run dry and end that run being rained on. With a top like the harrier, I don’t have to worry about getting caught in the rain, because it retains warmth even when wet. To me, the real magic of this top is that it doesn’t smell after one run (or two…or three…) like synthetic tops. I can comfortably run anywhere from 35-55 degrees F in ... Read more

The perfect base layer for super cold days that can hold its own on days when the chill isn’t so bad. It’s lightweight warmth but regulates the heat so well that it’s still comfortable when the temp gets above 45/50 degrees. I wear this all the time, seriously it’s so great!!!

Loving the Harrier long sleeve for my training runs these cold days ahead of the NYC Half Marathon. Pairing with a wind proof jacket is just the ticket to keeping warm and comfortable.

I'm a runner and have a runner's body, 5'9", 145 lbs. I love Tracksmith's clothes because they are high quality and fit me. I have over a 1/2 dozen Tracksmith tops in size medium and love them all. The original Harrier I bought a couple years ago is my workhorse. It's so versatile, and I use it all the time from Fall through Spring. I've been trying to buy a second one since Thanksgiving but ... Read more

Even More Hardy Harriers
For more than a decade we’ve pioneered the use of Merino wool in high-performance running apparel, leveraging its natural ability to regulate temperature and resist odor for countless miles. It’s a key component in our longstanding Harrier Long Sleeve, an enduring element even as we’ve refined the style over the years. Our latest edition features an updated silhouette with thumbholes for comfort and coverage. Cut from a heavier knit blend and powered by 37.5® Technology, it pairs innovative thermoregulation with Merino’s innate odor resistance for a technical top that breathes easy and bears the chill.
- Designed for running in cool to cold conditions
- Made in a Merino wool blend
- Thermoregulation powered by 37.5® Technology
- Finished with a thumbhole on the inside seam of each cuff
- Reimagined relaxed silhouette with raglan sleeves
- Body Fabric: 50% Merino Wool (17.5 micron) / 41% 37.5® Nylon / 9% Nylon, 205 gsm
- Odor-resistant, even if you skip laundry day
- 37.5® Technology for optimal temperature regulation and moisture management
- Machine wash cold with like colors. Delicate cycle. Do not bleach. Do not use softeners. Lay flat to dry.
- Our most relaxed fitting technical long sleeve, featuring raglan sleeves, a classic crew neckline, and thumbholes to keep you comfortable while running in cold weather.
Key Features
Merino is Magic
Merino wool marries an ultra-soft handfeel with organic functionality. Trust us – we’ve tested the Harrier ourselves, wearing it run after run without washing to find that it’s virtually impervious to odor. It also wicks away moisture and regulates temperature to keep you comfortable for miles.
37.5® Technology
With the 37.5® Technology, the blend comfortably and efficiently maintains your ideal body temperature by managing moisture before it even turns to sweat. Infused with mineral-based volcanic material, the long sleeve allows for optimal thermoregulation.
Reliability, Reimagined
Upgraded for a more relaxed fit with raglan sleeves and a thumbhole on each cuff, this tried and true, technical layer is made for whatever coach or the conditions throw your way. The reimagined silhouette is built to match the rigor of your runs year after year.
