A down vest is an indispensable piece for layering. You can easily store it in your backpack during hikes, but as soon as you stop or the temperature drops, you can put it on and benefit from instant warmth where you need it most. The Diablo vest not only offers these properties, but is also lightweight, because it is made from responsibly sourced 700-fill power down. Pair it with a shell jacket and a fleece mid-layer for complete weather protection during your hikes.
