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. The Session Quarter Zip in Tracksmith's Tencel-blend Session fabric — the mid-weight layer for October on the Charles, April in Toronto, every cold-start morning that warms up by mile three.
