Your list will vary obviously in different seasons. It would help if you specify what time of year this is for and also keep in mind that weather plays a part. That being said, you have a pretty decent list that just needs to slim down a bit. Please take all of my suggestions with a grain of salt. They are not best practices and rather just what I do. You asked though. Also, if anyone disagrees, I would love to hear why so I can better my skills as well.
1. Sox- Why not just sleep in your "extra" dry socks instead of bringing the 3rd pair. Do you really need 3 pr for 2 days?
2. Pants- In Colorado, I have never needed more than a shell and 1 lightweight polypropeline base layer. If you are colder, you may want up to capilene 4 or fleece pants under. In summer, obviously you only need light weight
non-cotton bottoms. I recommend cheap sierra designs or equivalend rain pants in summer if you don't have a shell.
3. Underwear- 1 pair would be fine for 2 days. If you don't agree, turn them inside out
4. Jackets- You either need a goretex type waterproof shell or a lightweight marmot precip or similar in summer. How are you going to stay dry?
5. Fleece- Great for summer but you have a softshell. Don't need both. Winter add a puff jacket.
6. Hat- Winter obviously you need a warmer hat whereas summer you don't.
7. Sunglasses- need to add goggles in winter.
8. Bivy under layer? is this necessary?
9. Flashlight? really. You have a headlamp.
10. Crampons. Maybe- depends on conditions
11. Swiss army knife. No. You have a multi-tool.
12. Fire kit? is this more than a flint and lighter?
13. Wipes? what for- only 2 days. choose wipes or hand gel.
14. Toothbrush/paste- no. If you are solo, who will you offend. Just rinse your mouth with whiskey.
15. Soap- no. Rinse your pot with boiled water. Clean it when you get home.
16. Paracord- is this enough to tie up one of your stuff sacks as a bear bag?
You should not have this much weight
when you don't have a tent.
In the past, I have been a guy who brings way too much stuff. Your list looks great compared to what I used to carry. It has taken me trial and error to figure out what I really need.
emergency blanket? (ya got a bivy bag and sleeping bag on the list)
I was going to say this too but you may want to leave this at your camp to keep your gear dry meaning you may want that e-blanket.
