I had discovered previously that putting the pad on top of the Hennessy open cell foam pulled it away from the hammock creating cold spots. Things seemed pretty warm and I fell asleep.
I awoke some hours later a bit chilled. The rest of the night was spent managing the cold. I never really achieved comfortable warmth but I was never really cold enough to keep me awake. I would get cold, shift, pull the quilt tighter, and drift back to sleep.
The quilt was great, the problem was the bottom insulation. I just couldn't get it right. I know that the 3/4 pad shifted down as the night went on and slid down, exposing my shoulders. At 5:00 am, I put on my long sleeve shirt, my pants, and my gloves, but they really didn't help much. I did have more clothing that I did not wear. If I had been out on an actual trip I would have put on my polar fleece and rain jacket/pants and/or opened up a chemical heater. I doubt I would have suffered but I wanted to find the limits of my setup and I think I hit it.
I am going to make some DIY quilts to compliment my No Sniveller and I'm interested to see how low I can go with a top/bottom quilt set.
Well, durn it FTW, it looks like the SS is just not going to do it for you below 50 or so. Sorry to hear that. But didn't you get much lower on your 1st report, 36* or 32*(frost)? Or was that someone else? You did use the space blanket on top of the HH pad, didn't you? I know many think they don't do much, but I always seem to notice a significant dif. Maybe it's all in my head. But I remember one night the backs of my legs(calves) got cold at 38*. Later, just by adding the SB, I was good to a little below 30*.
On the outside chance you should find yourself using this again ( if all your quilts are used by someone else), put a garlington insulator under
the pad. Cheap, light, much help. Or if you have light clothes you are not wearing, put them on top of the pad. Heavier clothes, under the pad, but make sure it's not heavy enough to pull the UC down, or adjust suspension accordingly.
The first time I ever tried to use mine, I put my 3/4" thermarest ultralight under the pad. I nearly froze ( violent shivering) at 23*. I didn't do that again and was fine. All it did was pull the UC down making a big gap. I later learned that TH specifically warns us NOT to put a pad either in the UC or on top of the pad.
You need light weight, very flexible items in the UC or on top of the HH pad. A stiff pad will just mess things up. Though some say the very flexible Gossamer Gear pads can be used. But if you think about it, that thermarest should have kept you more than warn enough in the hammock, all by itself, without the SS, at 40* or lower. I think I did 37* with just a Ridgerest in an SPE and was fine. The fact that you were cold with pad AND SS should tell you that something is wrong.
I also love the kidney/torso pads. They don't weigh or cost much, they compress small, they stay put, and they REALLY warm things up right where you need it, under your butt and kidneys.
Using some of the above combos, I have done the high teens OK. Last Easter, with 25-40 MPH winds that rocked my hammock and pushed my tarp against the hammock side all night, high humidity and 27* actual (wind chill?), I was nice and warm with the regular and kidney/torso pad, space blanket and a Garlington insulator under the pad at butt/legs, a down vest under upper body. Again, sorry to hear it's working so poorly for you.
But, like FB says, all you need is a pad of adequate thickness and NO SS or quilt. Much cheaper, works, and an SPE makes pads very manageable in a hammock. Of course, lot's of folks don't like laying on a pad, feeling it takes away from hammock comfort. Though I think Slowhike feels the opposite.
