I think it’s important to look at the temperature ranges represented, and not just the colors. The temperature range of the Nemo Tensor was 7 degrees, compared to 5.7 degrees for the NeoAir. That’s not that big a difference. The Static V had a whopping 18.4 degree temperature variation.
Also, the “warmest” area (where the most heat was being lost) detected by the NeoAir was 66.5 degrees, compared to 67.6 degrees for the Nemo and an awful 79.3 degrees for the Static V.
I don’t recall where I read it, but I seem to recall at least one person claiming that the Klymit Pads are better used with a sleeping bag that has loft on the bottom of the bag that can fill in the uninsulated gaps between the ridges. As a quilt user, the Klymit pads would be one of my last choices for a sleeping pad if cold ground was a concern. I own, among others, a Klymit Static V Insulated Lightweight, a Klymit Static V Insulated UL, a NeoAir Xlite, a NeoAir XTherm, and a Nemo Tensor. The Klymit pads are mostly relegated to summer time camping with my grandkids.
I’ve not been impressed with the S2S Etherlight XT based on reviews and specs. It seems to perform poorly given how heavy it is and how large it is when rolled up. Also, I consider the NeoAir Uberlight to be borderline “stupid light”, or a summer season only pad for mild temperatures when pack weight is a person’s primary concern.
