Generally, the cold is an issue when sitting. I am a huge fan of puffy pants with a zipper on each leg from top to bottom. They are very packable and they add tons of warmth when sitting. I reluctantly added them to my kit in 2023 and have used them less than 10 times, but I have loved them when I have used them.
