Here are items I use the most.
The big sack on the left is used for extra clothes, food, FAK, and small items (Food, FAK, Personal items are in Ziplocs for easy viewing).
Notice the holes in the big sack. A mouse!
The Foster Keg set up is always put into this sack. Perfect size to keep it snug and the lid secure. Other than being dirty inside (Esbit residue) and out it has held up well. For long trips of several days, I keep some cash, driver license, and ATM card it it. Cuben hold us well, unless you are dragging it across abrasive surfaces.
I have a Cuben quilt, and it still looks new because I baby it. Cuben seems to soften over time too.
As far as clothing, I would not recommend it unless you have used VBL garments and are okay with them. I have to vent the quilt at times. I recently bought a Cuben poncho and it has rained almost every weekend, so I have a lot of experience in a very short time. Very happy with it, and the sides and front zipper work to vent it.
One other thing, a couple weeks ago my wife and I did a loop in the rain and decided to hike back to our car through town. I asked her if I looked like a homeless person in a trash bag with an unkempt beard, and she said yes... so we stopped at Starbucks. They were not super friendly towards me :(
