This is my favorite long sleeve! It keeps me warm and I like that I can use it for multiple runs before needing to wash it.

I run in these tops more than anything else for nearly 3 seasons of the year, either on their own or as mid and top layers, depending on weather. Perfect weight, perfect quality. Please never change a thing!

My Go To Shirt

These shirts are my favorite! I reach for them all the time (in fact I have 3 long sleeve and 1 short sleeve). They are a work horse of a shirt -- good for any type of run you can throw at it. Long? Speed? Tempo? Easy? I choose this shirt for every run. Great by itself or layered under a jacket or a vest. Fits true to size. Would love to see some brighter colors!

I love the quality of this long sleeve. The material is thicker but even on slightly warmer days feels breathable.

The perfect long-sleeve for this transitional weather, and I would imagine can be layered during the winter months quite easily. I've run in rainy conditions and haven't yet washed it (!) just hung to dry and it's been remarkably stink-free. Super comfortable. Runs true to size.

This is very nice shirt. I gave it a four, because I find it hard to get my head safely through the neck without dragging it over by pierced ears and makeup etc. I really appreciate necks that have enough give to comfortably get over my head. Otherwise, great shirt.

This is my third Harrier long sleeve. I also recently purchased a short sleeve. I love that it never feels too warm or not warm enough. I was a bit concerned about wrinkles after the first wash but as it dried and I shook it out, the tops look great. I will say that the torso showed a little twist in the shaping, but its not noticeable when its on. Totally digging that I can use em as running gear... Read more

A lot warmer than expected, this pulls double duty as a base layer with a quarter zip to provide plenty of warmth on days when temps drop under 30degrees F. I’ve worn it multiple times without washing and it truly doesn’t hold the workout smell and still looks brand new. Very happy with my purchase.

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
  • 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.
  • A relaxed fitting technical long sleeve with 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 with a convenient thumbhole on each cuff, this tried and true, technical layer is made for whatever coach or the conditions throw your way. The added detail keeps your wrists covered and sleeves in place, so you can feel confidently covered in the cold.
