This vest is so many things: insanely light, packable, super warm yet prevents overheating. The air-permeable fabrics allow a small amount of air in to evaporate sweat, while the polypropylene synthetic down insulation keeps your core warm. It fits and feels like a warm mountaineering vest yet weighs next to nothing and even packs away into a jersey pocket when not needed.
