Session Quarter Zip

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.
