The need for something "waterproof" was noted in a number posts. Maybe I'm the only fly-fisherman in the group but has anyone thought of using a wading jacket? There are quite a few on the market -- just take a look at teh websites for Sierra Trading Post, Cabela's, Hodgman, Orvis, LL Bean, Simms...pretty much anyone who manufactures or sells fly-fishing clothing and waders will carry something.

Most are in muted, natural or neutral tones (lots of khaki, med-brown, greens) but you'll find exceptions. They're usually water-resistant as a minimum and waterproof as the norm. They're proportioned along the Ike/bomber style. Some are insulated.

I have a really nice slate blue, insulated one from Hodgman that saved me from hypothermia after a brief, unexpected swim one 40-degree late fall day a couple of years ago. If it gets brisker than its insulation might combat I just add a Polar Fleece vest or pullover underneath. I'll have to see about getting a photo.
