Lots of variables here.
Temperatures, are your action layers and/or base layers wet, down sleeping bag vs. synthetic, etc.
My default, if temps are mild and I'd relatively dry and comfortable, is to sleep in my action layers. Sometimes with base layers on underneath if temps dictate that. More often than not my action layers would be softshell pants and whatever wind/warm layers I wear on my upper body while hiking on a typical day.
I strive to not bring anything "extra" on backpacks hunts, only what is needed to get by and be comfortable, relatively speaking. Socks are about the only things I bring more than one pair of. That having been said, I am pretty tolerant of and used to getting by with single pairs of things like underwear and base layers for weeks at a time having gone 36 days in the mountains without the chance to shower...
