Not a wading jacket, as such ...
... but one of the really good waterproof / breathable, and light weight jackets around at a pretty reasonable price. Follow the link.

This jacket has been around for a long time with very few changes. It usually gets rave reviews, but note that the reviews at REI seem rather inconsistent. Think in terms of more moderate weather, wind, and activity level and most of them are very favorable.

P.S. If you join REI, at the end of the year you will get a dividend of 10% of the amount you spend there. At least last time I checked. Best to look for yourself if you decide to give them a try. REI, by the way, probably has the best customer service of any company that I have ever dealt with.
