I'm trying to decide if I'm better off getting a pair of rain-proof/resistant pants that go right over my longjohns, or a pair of rain-pants that you put on over your normal hunting pants when its wet.

Hunting in the Kootenay area, October-end of season theres enough dew/snow built up on vegetation that 10 minutes after walking the bush the water is running down into your boots.

I'd prefer the simplicity of rain proof main pants, but are they going to be too hot/non-breathable if you get some warm late fall weather?

Any thoughts or recommendations?
