Point-you may want to ante up to a pair of neoprene chest waders, 4mm are good weight. Otherwise if you go too low-you will end up buying another pair in a year. If you do some bush whackin-get a tube of Auqua Seal too. I have 2 pair 1 Bare(stocking foot)and 1 Kobuk (boot) the Kobuks almost look like they have been dipped in Aqua Seal.
