For the ultralight minimalist who requires functionality and style, our Zetto Jacket is a light-as-air layer for performance and warmth. Designed with technical offset quilting using bluesign® approved materials and insulated with 850 Fill Power DownTek™ water-resistant down. Built to perform as a mid-layer for stop and go cold-weather sports, and warm enough to be your outermost layer on a bluebird winter day. We constructed this technical performance piece with materials that provide weight savings and simplicity so you can stash this insulated layer on the go all year long.
