M Harrier LS

Even More Hardy Harriers For more than a decade Tracksmith has 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 Tracksmith's longstanding Harrier Long Sleeve, an enduring element even as they've refined the style over the years. Their 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.
