Hi, I'm taking 3 people with me to a hang this weekend where the overnight temps are supposed to be 27 degrees. Two of these people are my kids and the other is my girlfriend, so I feel at least a small responsibility to keep them alive and/or not miserable

For one hammock I have a down underquilt that's really only good to about 35 degrees. If I add a 1/8" Gossamer Gear CCF pad inside the hammock will that help or hurt? I also have some reflectix I can put under the feet and around the shoulders.

The other two hammocks will be dependent on pads. I have a Thermarest Neo-Air Xtherm which has an R-Value of 5.7 (on the ground), but I'm assuming it would be warm inside the hammock as well? The other two pads I have are an Alps Mountaineering Comfort Series self-inflating pad and a Wal-Mart blue CCF pad. Which of those two pads would be better?

I can supplement any of these with Reflectix and/or a space blanket.

How would you do it?
