Women's Session Quarter Zip

Tracksmith was founded in Boston in 2014 by Matt Taylor — a Yale track alumnus and former Head of Running at Puma — and Luke Scheybeler, co-founder of Rapha. The premise was simple and stubborn: the amateur Runner, the post-collegiate competitor, the sub-3 marathoner with a day job, had been forgotten by a sport that only sold to pros and beginners. The debut collection in 2014 was two pieces, the Van Cortlandt Singlet and Van Cortlandt Shorts, and a decade on the Van Cortlandt fabric is still the racing line, the Cornell-derived diagonal sash is still the mark of a scoring athlete, and the hare — drawn by British illustrator Gary Chalk and named Eliot after Boston's legendary runners' bar — is still embroidered at the chest. Boston-born, Ivy-sashed, published in its own quarterly magazine (METER), and honoring the Amateur Spirit upon which the sport was founded.

The Session Quarter Zip is the layer you pull over a singlet on a 50-degree morning and pull off by mile three. A Tencel-blended 200 gsm fabric (33% Tencel, 33% Poly, 31% Nylon, 3% Elastane) with Nilit Cooling yarn that feels like a sweatshirt and dries like a tech tee, with a zipper at the collar that vents heat on demand and a close cut that layers cleanly under a shell. The hare sits embroidered at the chest, quiet as usual. For October on the Charles, April in Toronto, the shoulder seasons when you're never quite dressed right at the start. A women's silhouette in the same Session Tencel blend as the men's — same vented collar, same proper-noun fabric vocabulary, same October-on-the-Charles use case.
