We were emerging from a cave two weeks ago. Outside, the weather was wind, rain, and snow. Inside, the cave was a bit drippy. When we got out to our cars, we looked like a bunch of refugee earthworms. One guy had neglected to bring along any change of clothes, so he was forced to drive home that way, and I would hate to think what it did to the car interior. As I've said, coveralls are not very high-tech, but they work. For that trip, I was wearing winter-weight fleece tights underneath the coveralls, and that was probably a mistake. I should have worn the summer-weight tights.
The whole thing is that you have to know something about the cave that you are headed into, and you have to know how fast or slow your own metabolic rate is so that you know how much heat you have.
