Lightweight, insulated, breathable, air permeable. In layman's terms, for working hard and building up a sweat in cold weather, this jacket lets hot air out and just enough cold air in to keep you at a stable temperature. As a standalone jacket or as part of a layering system with a breathable shell, this is a useful bit of gear for the changing of the seasons.
