Since I started researching lightweight backpacking, I've frequently come across the suggestion of incorporating your clothing into your sleep system. This always comes with the caveat, "If you're in bear country, don't sleep in the same clothes you cooked in." However, this advice typically comes from the same people who say don't bring extra clothes. So if that's the case, what do you wear when you cook? This is probably a dumb question, but I can't seem to wrap my head around it. Do you bring a change of camp clothes and wear that while cooking? What if the it's cold and you need to toss on your wool pullover? You're likely to be cold enough to want to wear that pullover in your sleeping bag/under your quilt. What are the expert opinions on the matter?
Thanks!
