Are you looking for one of the jackets that is designed to replace a fishing vest? (the kind with all the pockets, nipper retracter,etc) or are you looking for a jacket that you will wear underneath your fishing vest?

If you are looking for a jacket to wear under a vest, it's hard to beat the Marmot Essence jacket. It's super lightweight, compact, waterproof/breathable, relatively short waisted, and reasonably priced ($112 for last year's colors)

I have one and like it a lot.
