...Feet will get wet riding even with waterproof socks, so I wear dog poo bags over regular socks mainly for warmth...Keep your sleeping bag dry!! 😊
The "Bagtex" method is high on my list too. I pack a couple of bread bags for that.
If the clothes you need the next morning are wet when you go to bed, I've found that putting them between my sleeping pad and the tent floor often dries them out. At least it keeps them a tad warmer, or thawed out, and easier to put on wet in the morning. You need to ventilate your shelter well enough for that to work. Sometimes if it's not too humid, I'll wear hat and gloves to bed to dry them out directly with body heat. Definitely, keep the bag dry! I'll stop at every sun break the next day to lay out camping gear, to try to get a dry start to the next night.
Experience is often more important than gear. The priciest breathable down gear quickly becomes useless if you don't know its limits or how to care for it.
