Lucky me but I'm both able to carry redundant winter layers PLUS have the ability to carry enough food for trips up to 24 days in length without resupply. The best of both worlds.
In fact one of my longest trips was a 24 day swaray in January 2014 whereby I was able to carry both my excessive clothing layers AND my ginormous food/fuel load--- Am I lucky or what? And during the trip I got to experience the so-called Polar Vortex of 2014 with temps on the Brookshire/BMT down to -8F---and 2 zero hunker in days in the tent. Clothing layers and overkill gear came in handy.
I pulled 105 miles on that trip even with my 100+ lb pack---so it was a very successful trip. Here's the demon anvil from that trip---
