I'm a big fan of these jackets
http://www.safermoto.com/index.html. The built in airbag provides an extra layer of safety that is unparalleled IMO. The price isn't much more than some other good, new jackets without airbags. They've also got vests with just the airbag portion if you already have a jacket you like.
If you're in the market for something used because of coast, these might not be the best option, but for a new jacket, the price is comparable to other jackets.
It claims to be water resistant. I stay dry inside, but the jacket still gets plenty wet. In heavy rain I will throw a bright yellow rain coat over it. Keeps me very warm, more visible, and plenty dry.
You might need to order 1 size up. They're super good about returns if you get the wrong size.
