Here's my setup in action:
It's all CDW.....what I have in there:
In the front I have a Phantom 32 down bag, a Mountain Hardware synthetic puffy and a REI minimilist bivy.
In the rear I have Don Miguel burritos (The Bomb-Green Chile & Breakfast Burrito - Bacon), assorted food snacks which I'm not accessing that day, a MSR water filter, sleep clothes (wool beenie, Capeline2 zip-up by Patagonia, boxers), travel tube of chamois butter, travel tube of diaper rash cream)
On my back: WingNut pack containing a 6L MSR dromedry bag, snacks for the day, extra change of batteries(rechargable), multi-tool and all that other crap you normally take on a normal ride (tubes, patch kit, yada yada yada).
I don't carry a sleeping pad...if you ride hard enough....and if you bikepack, you ride hard enough....you don't have trouble sleeping. I can usually find good ground cover to make something soft to sleep on. Only if there is snow on the ground will I go for a sleeping pad.....YMMV
