We live in Atlanta. Unless you live somewhere very cold, this is all the jacket you'll need. Their version of Gore Tex, the seem sealed microfiber is windproof and waterproof, which greatly helps with warmth. Rain hood folds into neckline to create a crisp collar. Packs very easily with no bulk. Generously sized, so add a sweater or fleece underneath and you'll stay warm when it's cold, wet and dreary. My husband loves these so I bought him two in different colors.
