Endgame clothing needs on voyager?

I'm setting up for a long term voyager run and want to confirm if my intended clothing setup is good enough for the endgame. Is there a threshold to aim for in terms of warmth?

In case you're curious, my intended setup is:

Wool toque+balaclava, 2xFishermans sweater, expedition+urban parkas, gauntlets, wool earwrap+moose hide satchel, combat+snow pants, 2xWool longjohns, 2xClimbing socks and Mukluks
