I've used the full setup twice now, for 6 days total, and the quilt-top twice now, for 4 total days. I purchased this thing for over-landing, originally, because it's massive, heavy, and I've taken my KSB 20*F down to 0*F with no problems. I take my two Shepard-Huskies backpacking/car-camping a lot, but am always worried for them when it gets cold -- call me soft. The little lady, and both dogs can pile into this thing. I needed a way to get her out into colder weather, too, and this was her soft entry. We split-carry with the KSB Double-Insulated pad, it fits fine inside of my Tarptent Double-Rainbow, and we don't have to deal with two separate sleeping pads. SHE likes it, and hasn't complained about being cold, and that is a huge victory for me. I'm alright with the bottom insulation, though I wish it was just thin fabric or something. I prefer this because I don't like the feel of sleeping pads against my skin when I'm warm/hot/sweaty if I can avoid it. I understand wanting to go lighter weight, and do. This is roughly an 8lbs setup, split between 2 people, and covers my dogs -- it's not THAT egregious, weight-wise. I'm happy with the purchase - hike your own hike. There is some form of DWR on the quilt-top. I flipped it upside down accidentally, and woke up a little moist. Right side up, I noticed no issues. The quilt is large enough to cover she and I without taking the base, YMMV.
