Merrell Gatherer Jacket

One of the biggest problems with normal jackets is their inability to deal with changing temperatures. The Merrell Gatherer Jacket ($100) overcomes this by utilizing a system of adaptive insulation pockets that allow the wearer to add and remove insulating materials like pillow stuffing, packing peanuts, newspapers, leaves — basically anything you can grab — making sure you stay comfortable whether it's 40 degrees or 40 below.
