Outdoor Research Men's Size Chart Built with a durable 20d ripstop and cozy polyester, and injected with the all-new VerticalX(TM) insulation, the Kalaloch is the perfect piece when you can't decide between a puffy jacket, a super warm blanket, or a comfortable, casual flannel. Built to kick bone-chilling temps to the curb, VerticalX(TM) technology is the high-loft synthetic insulation with a superior warmth-to-weight ratio, breathability, and moisture management for all of your favorite cold weather activities.
