What months are you going?

I found with good campsite selection (don't sleep near lakes, meadows  
or other cold, low places) that I was toasty warm in my ultra-thin  
silk underwear or just my clothes without long underwear. Only around  
4am or so would I wake up and put on my down sweater to eek out a few  
more hours of warm sleep. Only once was I ever truly so cold I slept  
in multiple layers, and that was when I camped near Tyndall creek.
