The North Face Men & S Thermoball Active Vest - Monument Grey CHN7N_AH287

Product details:

Versatility on winter training days is finally doable with the new Thermoball Active Vest. This durable training vest is insulated with TNF's tried-and-true ThermoBall insulation, which is a type of synthetic insulation developed by the engineers at PrimaLoft. This material mimics down feathers and traps warm air within millions of tiny pockets; ThermoBall insulation has the same weight and compressibility as down, and works even when wet.
