WB Traveler - Cold Weather Insulation

[longbow]

I posted the question below on another thread and received no response. Perhaps this is the place for my question.

I recently bought the Warbonnet Traveler sold on the HF "gear for sale" thread for my 17 year old son. I haven't had time to fine tune the insulation approach yet. There may be an UQ in the future. But, I don't want to rush that purchase until I can shop around a bit. For the short term, I have some Thermarest pads and a CCF RidgeRest pad that I can use. We are planning to participate in the Arizona Canyon Creek "hangout" on November 21-22, which might present temperatures around 20 degrees, or slightly lower.

Here is the question...

I tried setting up the new WB Traveler with a Thermarest Camp Rest (30"x76"x2.5"). It just seemed too big and bulky in every way. I let out some air, and still no help. I then tried a 20"x72" CCF RidgeRest; the fit was very much better. The CCF pad just seemed to conform to the Traveler in a better way. I slept in it last night in the backyard, and it did very well between 40-45 degrees. But, I am concerned that below 20 degrees, the RidgeRest won't cut it. Should I add a second CCF pad? Or, is there another approach I should be thinking of?

The sleeping bag I used for my backyard test was a NF 30 degree down bag. I will be putting my son in a NF -15 degree bag used as an over quilt or zipped up within a NF Gore Tex bivy sack for the upcoming trip. Maybe that will be enough.

Any suggestions will be much appreciated.

Get an SPE from Speer Hammocks and use two pads of your choice and you are set!!!!!!
