Built for any cold weather activity outdoors, this cozy vest uses the same fabrics as our Odin Stretch Insulator jackets, giving you maximum freedom of movement and lightweight warmth. Primaloft® Gold Active + is unmatched warmth designed specifically for high-output adventures. It lets excess heat and moisture escape, keeping you comfortable and dry. Use the vest as a midlayer under a shell for colder days outdoors, or a standalone outer layer once the temperatures rise.
