The Patagonia Down Sweater Vest reverses to give us two distinct looks in one layer, switching between on-seam zip pockets with a hidden security pocket on one side and simple drop-in front pockets on the other. Underneath, 800-fill-power down keeps the vest warm at just 5. 3 ounces, light enough to stow into its own pocket when the temperature climbs. What Our Gearhead(R) Experts Are Saying:"I flip mine to the drop-in pocket side for casual days and back to the zip pockets when I need something secure on the trail, and both sides feel like the actual front of the vest, not an afterthought. It packs into its own pocket small enough that I stopped leaving it in the car."
