Other than the camp chair, I don't see anything out of the ordinary item-wise, although the Q-Core is inordinantly heavy
No way I am sitting on one of my Ortliebs, especially if it's muddy. There might be hard items in them like a pump and tools. And using one for a chair necessitates taking it off the rack, which many times I don't bother with. I bring a 12 oz. plastic tarp. Great for two people to sit on and can be used as a shelter to cook under in wet weather. The tarp goes on the rear rack under the tent so it takes up no pannier space.
Never do I unpack all my gear on any given day. I take out what I need for the day/night and leave the rest packed. If I need to get out quickly the next morning, I a make sure I am prepare the night before by making sure I have packed everything I won't need the next morning.
Don't think a half a body legth of bubble warps is going to cut it when it's literally freezing out, especially for sometone like me who is 6' 2" and over 200 lbs. I will stick with my Therma Rest Pro Lite 3 or Big Agnes Air Core.
My GF uses a Cocoon pillow. Takes all of 3 minutes to pack up, weighs 3.5 oz. and is extremely compact. I simply stuff my sleeping bag sack with the clothes I will wear the next day and cover it with my towel.
Unless you are riding long stretches with no services, how much water do you need to carry?
