Bibs will not keep you dry. They might be water risistant but they are not waterproof unless you buy some that are specifically so. Then they'll probably cost you the same as a cheap pair of waders. You can get a really nice pair of neoprene waders from BassPro for under $100. The canvas ones are even cheaper. Walmart sales the rubber waders even less. A set of insulated bibs that are waterproof will easily cost that much. Plus no, bibs dont attach to your boots to keep any water out.
