Multi-purpose jackets aim to do more than one thing well, but usually end up being one trick ponies. This isn't the case with the Aether Nimbus 3-in-1 Jacket ($825), which was created so that each part could stand alone confidently, regardless of the weather. The fully seam-sealed shell is made from a 3-layer woven-wool fabric with a tricot backer. Hidden snap connectors keep the vest, and the clean design intact when it's worn on its own. Add on the exterior zippered hand-warmer pockets, a zipper garage at the collar, and a zippered interior pocket, and you have a jacket that is not the only multi-purpose, but practically essential to put on before going out.
