Obermeyer Zurich 1/2 Zip Sweater - Men's: Slip on the Zurich 1/2 Zip before you boot up or head out for a quick hike. This sweater is just as comfortable at high speed descents as it is kicking back after a sauna. The half-zip construction makes it easy to vent and the Merino/Acrylic yarn is super comfortable. A technical heritage inspired design is an Obermeyer focus.
