A day of wandering a new city swings from cool mornings to warm afternoons on the move, and the Dumji Full-Zip Jacket adjusts to both with a single zipper. The full-length YKK zip opens to vent when the pace picks up and closes again when the air cools, so this sweater jacket stays on through every change in temperature. Extrafine merino wool and a little alpaca keep it warm and breathable, and the ribbed collar, cuffs and hem add a snug finish. A Nepalese-inspired pattern across the chest and prayer flag tape on the zipper pull bring character to the knit.
