I have a HH Deep Jungle XL zip with the reflecting pad, but I've shipped it to Hennessy for a repair (this is my 2nd time sending it back, due to my own faults, not there's). It takes awhile to get it back fixed and I'm worried I'll miss the Florida cold-weather season and not have a chance to cold-weather camp in it. Its fine in the summer months when I've used it and I also have a Hennessy Safari for the summer - I'm a big guy and need lots of room!
Anyway, who has camped in one during cold weather? Does the reflecting pad do its job in the 20's? I'll have a zero degree bag I'll be sleeping in so don't need a top-quilt.
It is as warm as the insulation you surround it with.
But I guess you are actually asking about the radiant bubble pad? I think it is "officially" rated by HH to 40F, but don't hold me to it. I think HH does not rate it quite as warm as the HH Super Shelter (HHSS) system, which many people have used successfully to about 30. Some do better than that, some don't do nearly that good. But if the radiant bubble pad is not quite as warm as HHSS, adjust your guess accordingly.
Also depends a lot on what kind of layers and bag you are using. Multiple layers of fleece or other synthetic clothing or bag (if used as a bag but not as a quilt) will add a significant boost on the back, but not so much with down bags or clothing. Because down compresses with your body weight so much better than synthetics, especially fleece. And of course a quilt, or bag used as a quilt, offers no extra warmth to your back other than what your pads or UQs might offer.
You say you sleep on a WM blue pad? Well a lot of people get down pretty close to as cold as you are going to see with just that and nothing else under them. Since they are so cheap, buy another one and cut it up. Use one section of the new pad added to your other pad to make a "T" shape, so it will be plenty wide enough for your shoulders. But this will also double thickness, greatly increasing already significant warmth in the area of the "T". Use some of the left over to double thickness at your lower back and butt. You are not likely to need anything more than the one pad for your legs.
You will have to figure out how to hold them together: an SPE, or glue or duct tape or poke some holes through the top and bottom pads and run some cord through the lined up holes.
Of course, you can probably also use the blue pad with the bubble pad and get more warmth than either together, but how much, who knows?
If your bag is a roomy one and has a full zip, you might want to experiment with wrapping it around your hammock in what is called Pod style, if you can get your net well out of the way.
