What do you know? You're just a clueless weekender
. Just kidding, I'm with you on that paragraph. I use pretty cheap, non-breathable rain gear, with the knowledge that "warm and wet" is OK as long as you have plenty of dry insulation in the pack. There are exceptions, of course, like heavy wet snow combined with wind, when it's just really hard to stay warm when moving without extra insulation. You have to know when to stop and take shelter, and not exceed the limits of what you're wearing.
Everyone has said this except me. In certain conditions, like most of the time where I live in the Rockies, with very low relative humidity and good ventilation, and with warm sun at least part of nearly every day for airing out the bag, I can dry off small items of clothing by sleeping with them. Sometimes a warm, dry pair of socks or gloves in the morning is about the nicest thing imaginable.
You need to understand
psychrometrics, though (I've been wanting to use that word for years). I always wonder when I see a clothesline in a campsite on a cool, damp evening. How is that going to work in near saturated conditions?
