I've worn the following this year and it's been great. I've worn it in heavy downpours then removed it when the rain stopped and strapped it to my pack. In those cases I didn't wear a waterproof lower as I had rubber/neoprene boots on and only a small bit was exposed.

I have used it once with Lacrosse Grange Hip boot in a constant rain and it worked well as a pair....but I wasn't worried about the sweating then and sweating was a given with moving in that setup.
