I bought sets of windbreaker boating gear for my wife and me. They were "Against the Elements" pants and anorak from Boater's World. Very inexpensive (on sale at about $7.50 each item), but perfect for wear on dive boats under windy, wet and cool days. They are waterproof and lightweight (each item has its own stuff sack) and we travel with top only or both pieces, depending on where and when we will be. Not designed for northern weather, but with the wind cut off by the windbreaker over a wetsuit or T shirt, things are generally pretty toasty.
