You know what I use in the summer and thru most of the fall...and it is really excellent is this jacket I bought in west marine a few years ago called a "dinghy jacket" or spray jacket. It is made by GILL, is a light waterproof pullover with neo cuffs and neck and waist with velcro. This is one of my favorite surf fishing jackets over my waders and can go all the way till Nov in.
Check it out.

but when it gets really nasty...go for the grunden pullover, that can take anything mother nature can dish out. I have had trouble finding the grunden's pull over...most commerical guys don't like them I eventually ordered mine thru the surfcaster.
