Harrier Long Sleeve | Merino Wool Blend Running Top | 37.5® Temperature Regulation

Tracksmith launched in 2014 from Wellesley, Massachusetts — the halfway point of the Boston Marathon — with a focus on runners who aren't professionals but treat training like it matters. This long sleeve is cut from a Merino wool blend (50% Merino 17.5 micron, 41% 37.5® Nylon, 9% Nylon, 205 gsm) built for cool to cold runs. The 37.5® Technology works to regulate temperature and manage moisture. Raglan sleeves, crew neck, thumbholes at each cuff. Woolmark Rich Blend certified. Relaxed fit.

Raglan sleeves mean no shoulder seams to rub you wrong mid-mile, which is considerate until you realize it also means you can't blame the shirt when your form falls apart at mile eight. Eliot the hare watches from the logo, silently.
