1. 3/4 length Thermarest "regular" thickness PLUS full length RidgeRest beneath
2. 3/4 length Thermarest regular PLUS full length Thermarest Lite (1st light version they made in the '80s) underneath
#1 has been the warmest for me but not by much and the Light Theremarest packs down MUCH smaller that the RidgeRest, which is nice with all the other bulky gear for winter
I will not be using my Neo-Air in temps I know will be below freezing B/C I don't want any ice that may form inside from my breath condensation to damage the mattress when I roll it up.

I use a full length thermarest (trail model with no holes cut in the foam) over a full length ensolite pad. Very warm, but I am out in temps down to around -15F.
Have you tried the full length Thermarest lite orver the ridgerest?

At 0F, I use: GG Thinlight (2oz) underneath a GG Nightlight (8oz, ¾ length old style), bumps down. My bag is the WM Antelope in a GG Squall Classic Tent.
I usually can’t sleep on plain CCF pads. But for some reason, in the winter, they feel nice. Of course my WM bag adds a little plush even if it is scrunched.
In the summer, I switch back to my ¾ length Prolite 4 (16oz).
If anyone uses the blue foam mat in the winter, be sure it’s of high quality. Some of those walmart pads are terrible in R value.
Yes, I used my Thermarest Lite over the RidgeRest once and it worked OK but not quite as well as the regular thickness 3/4 length Thermarest.I have to add that with this 3/4 length mattress I use a closed cell foam 18" sit pad under my lower legs as well.

I'm happy down to touching into the -5 -7 centigrade range in my hammock. colder than that I go to ground with a BA insulated aircore. if it's getting below -15C I top it with a CCF foam pad. below -25C I usually end up with a sandwitch, two ccf pads with the aircore in the middle.
I used to use a regular thermarest in place of the BA, now I use that.

I use a blue 3/8" ccf mattress under my exped7 Down Air Mattress. I've taken this down to mid 30's in my hammock so this should be plenty good on the ground down in the teens.
