Alright, hopefully I can translate my thoughts into words clearly here...
Say a TQ has a given temp rating of 40*. That means that it would potentially keep you comfy to 40*.
Now, is that assuming that you have no pad or UQ? Or is it given with the assumption that you have that covered as well.
In other words, if I have a TQ good to 40*, and it is going to be colder, will adding a UQ help take that lower?
The basis behind my question is that I am trying to plan my setup now. With where I live, I probably won't be seeing temps much below 30* (for the most part, cold snaps not withstanding), and I would love to make a flexible setup that will see 4 seasons. I'm good with adding a blanket or clothing to go cooler, but I want to understand how all this works first
