The men’s DOWN Sweater Vest is a core-warmth-first engineered sleeveless for when the sun and mercury dip. 800 fill power high-loft down is powerfully warm and Advanced Global Traceable, ethically-traced. The recycled poly ripstop shell with DWR finish is flexible. The whole vest packs into the inner zip chest pocket, which converts to a stuff sack. The front Vislon zip has a wicking inner storm flap and low-profile zip garage. A drawcord hem tightens from inside the zip handwarmer pockets. Nylon-bound elastic armholes help keep the heat in the core.
