Are you expecting snow? if you're expecting a lot of it then
what I'd take in those kind of conditions is a couple of pairs
of medium weight wool or synthetic long underwear, a 200 or 300 wt fleece bottom, a nylon hiking pant and a shell pant (waterproof or goretex). normally I'd wear the regular pants, and slip on the shells if you're digging in the snow or the weather is foul.

I bring liner and three pairs of good heavyweight wool socks that fit in my boots, and gaiters. I keep one sock dry for sleeping in. If I really expect cold I'll bring my primaloft booties for sleeping.

On top, for me that's a couple of merino wool shirts, two 200 or 300 wt fleece (or one and a down sweater) and a shell jacket kind of trip.

I will also have a toque, ragg wool gloves, nylon overmitts,
and a balaclava for sleeping in.

that's pretty much it.

During warmer parts of the day near freezing and/or while active I'm probably moving in only the long johns and the pants, with the merino shirt and jacket on. Change it up for sleeping and add/remove when stopped or it gets colder. Keep one set dry for sleeping.

YMMV
