I was at north where there are no woods, so I needed something almost as comfortable as Hammock. And best part of these mattresses is that they are quite small when packed and relatively low weight (double weight compared to thick CCF but takes only half the space).
At some point I will test it with BB, but I think my version is too big to fit inside it comfortably.
OK, so that is a synthetic version of the Downmat. Yep, those are really warm. So if you are going to use it, you probably won't need an UQ in addition to the pad until temps get extreme. But even when they do, it would probably be easier to stack a CCF pad under the torso area, or even full length if needed. At least with an SPE, not sure how stacking will work in a double layer BB. Considering it won't make a comfort difference, because you are already on a pad anyway.
Now, if you want to get rid of pads for the comfort of an UQ, well that's different!
