I don't know what the issue with getting wet in waders is vs hypo..... seems if you didn't have waders on you'd be just as wet.....
I dont' swim. I wear waders when running the airboat( no level floatation) but I wear a PFD and also keep them loose and no suspenders on etc... so I can get them off if needed.
Being that once you are in water you are somewhat bouyant, I dont really feel that waders is as big an issue as folks make them out to be.
Having taken water on with waders on before also, I"m always glad I have them as teh waders will allow the water to at least have a shot of warming to body temp, vs no other insulation, IE wet pants exposed to water and wind....
