I have an inflatable pillow from the now-defunct KookaBay. I also bought a dry bag from ZPacks that has a fleece coating on one side (the dry bag turns inside out to expose the fleece). That bag is just the right size for my insulating clothing. The combination of the cuddly fleece, the air pillow, and whatever insulation I'm not wearing in bed makes a nice comfy pillow!
