A down vest is a fantastic layer-on-layer garment. You can easily put it in a backpack as you hike, but when you stop or the temperature drops, you can pull it on for instant heat where you need it the most. Combine it with a shell jacket and midlayer fleece for complete weather protection as you hike. The vest has a fill power of 700.
