No it is not stupid. A few problems to over come. It can still slip from end to end. Mats have to be the same width. Wait until after you try it. It still may not work. For camping in my Van It did not work and had to make a sleeve ( closed on 3 sides) . For a reason I do not understand when sleeping on a snow shelf I had very little trouble with slipping. I do have a thermarest sized piece of that no slip material that you put under a rug to keep it from slipping on a hardwood floor. I can’t remember how I used it. I don't think it works when it is cold so the mats slipped apart before they warned up.
I went on my first over night canoe trip in 1949. So I have had lots of time to learn. On my first Deep Freeze I doubled my wintercamping knowledge. The people on Wintertrekking and CCR are a great resource base.
Thanks  for all you have taught me.

I actually just started stacking two pads together and find it WAY more comfortable.  I don't do it for warmth and I only do it in the shoulder seasons or winter when I'm not in my hammock.  I have a Thermarest Mondoking and even at 4 inches thick my shoulders start to hurt in the morning.  I tried putting my Thermarest Neo All Season on top (held with a couple velcro stretchy straps) and man the difference is amazing.  I under-inflate both a bit and find it to be very comfy.  I always bring a spare pad with me anyway (I don't trust inflatables, especially on a winter trip) so I figured it was worth a try!

Hey GearFreak? What mattress were you using on the UL cot?

I cannot remember what or if I used anything.  I will if I use it in the future.

Of course S2S have brought out a new mattress that is thicker since my first post but even so it isn't any warmer, the R-Value of the mat is the same but mates who have purchased it say it is much more comfortable so stacking is still going to be required to stay warm. A sleeve in LW fabric doesn't add much extra, nor does LW tape.
There is a limit to bulk tho and the constant Law of Diminishing Returns, so going too thick on the CCF may not be the best option under the RidgeRest Solar, 12mm may well be too thick but 3mm may not be enough, how common are wide CCF pads to suit the wide RidgeRest Solar?

If it it too cold for my Thermarest Trail Pro self-inflating mattress over my Ridgerest CFC mat then I'm not going out. That combo on packed snow is good to -50 F. in a tent.

But what happens if you are already out and 4 days from a cabin?
People keep telling me to be prepared and then turn around and tell me I worry too much
Like I probably really do not need a -40 sleeping system but "What IF"??

Sea to Summit have a new double layer insulated mat out that is a full 80mm thick and rated at R5 which I have not yet had a chance to try out.
I am informed that it is super warm and very comfortable. Given what people have said about Thermarests being a little hard to roll out in very cold weather I have to think about investing in the new mat I think. I would still be using a CCF in various combinations as a failure of an air mat would be uncomfortable if not catastrophic
I bought a S/H Neo-Air to try out and I simply cannot get comfortable on it after using the S2S but it is a lot lighter, not anywhere as warm but a lot lighter

I just recently found stackable pads on Amazon.
I'm only one trip in on these, so time will tell, but they survived the initial testing in some -stupid temps :)

where do you guys even buy caribou hide?

Does raccoon fur provide sufficient insulation?

You don't buy caribou hide, you go hunting for caribou in the summer(august is the earliest for us) and then you keep the hide and you fill the freezer at the same time.

As for racoon, not the same haire structure than caribou so no it wouldn't be the same, that said it would still be warm! The reason for caribou is that the hairs are hollow like straws and that the hide after it's ben dried is really light, bulky but really light so it makes it favorable for traveling.

I mean now a day with all the new mattresses it is way easier and way more economical to just get a good mattress! And plus, caribou hide shed hairs a lot so if you don't want to look like a hairy mutt, caribou hides are not a good option...

Sito, raccoons are too small to sleep on their hide.
you can buy sheepskin from Ikea, http://www.ikea.com/ca/en/catalog/products/70026822/
they give good insulation,  easy to buy. and looks very comfy in the tent.
I am using old sheepskin jacket. insulates very well and bombproof not like downmats

Reflectix works well as a cheap alternative to CCF and is probably a lot lighter than a caribou hide.

how good is reflextix insulation?

I am curious.

I am told it has an R of 4 if separated by an air gap from the heat source but only 1 if in direct contact.

I think this means that if you lay directly on it not much but if you use an air mat on top it is pretty good.

Not that R values mean too much but they are the best we have got.

Getting ready for winter here and I have 2 older mats I am experimenting with, I have made some straps but they do not work as well as I would like, what works reasonable well with the straps are some stripes of roofing plumbing; the old fix for slippery mats; silicon to silicon with the straps on works OK
I think a full sleeve in a proper sleeping shell will be what I go with tho as I am going to be using a LW synthetic overquilt for deep cold anyway and it amalgamates it all in one package
