The Space Vest is designed to keep your core warm on cold winter days. It's insulated with 60 grams of PrimaLoft® ONE, which offers exceptional heat retention while remaining low in volume. Its shell and lining are made from a silky-soft microfiber ripstop fabric for a soft feel and a sophisticated look. Lightweight and highly packable, the Space Vest is perfect underneath a business suit or a ski shell, or it may be worn on its own on milder days. It features front hand-warmer pockets and an internal pocket with an audio-cord valve.
