A lightweight layer that insulates effectively, the Women’s Ultralight Vest provides versatile comfort worn solo or as a mid-layer in colder conditions. Constructed from a 1.5-oz. ripstop nylon shell, with 60g PrimaLoft® Gold insulation—the lightest-weight synthetic insulation we offer. Outfitted with a cotton Moleskin-lined collar and handwarmer pockets. Compresses small, so you can keep it in your pack, briefcase or shoulder bag—ready to deploy when the temperature drops.
