Simply put, the Aether Nimbus 3-in-1 City Jacket ($825) allows you to adapt to your environment. The shell is made from a waterproof 3-layer wool Schoeller fabric that keeps out the elements while being breathable and letting out sweat. The vest attaches to connectors on the inside of the jacket so no snaps are visible. The vest is insulated and provides that extra warmth on those frigid days that are coming. So whether you wear the shell, the vest or both you’ll be prepared for anything fall and winter can throw at you.
