Maybe they say so, but I don't know if in reality they're warmer. I have a Thermarest Neo Air Xlite and sleep directly on it as I use a quilt. When it's cold (below freezing), I have to put a closed cell foam pad on it otherwise I'll be cold. My pad is just an 1/8" thick pad from Gossamer Gear that weighs just 2.5 oz. December 30th I was out and the temps dropped to low 20s, maybe even the teens and I wished that pad was a bit thicker.
When it's warmer out, I put the Neo Air on top of the foam pad to help protect it.
I use the foam pad during the day for laying or sitting on during breaks from hiking, such as lunch and snack times.
