Get a vest from Orvis. It's $100 and the best one out in the market.
Given the competition out there, that's a pretty strong statement. I see a lot of nice features in several vests and packs.
Among my current favorites:
William Joseph Confluence
William Joseph Exodus
Fishpond Marabou
Fishpond Sagebrush
Fishpond Wasatch
Hardy EWS
Filson Guide Vest
I don't take anything away from Orvis, but there are a lot of good options out there.
