Which sleeping mat type is warmest/most comfy of classic foam w/ foil & Z-Rest?

[irrelevant]

Anyone possibly has experience with these particular ones? I'm trying to decide which to bring. Have used the classic kind every time so far, just was gifted with a 2nd hand Z-Rest. I need warm.

Classic foam **with aluminum foil** (example)

I’m pretty sure that the Z-Rest is warmer than the classic foam pad. ^^

Since a few years I combine my inflatable Therm-a-Rest with a similar pad to the Z-Rest (I use the Exped Flexmat, which I got cheap on eBay). This combination of foam pad + inflatable pad is a dream in terms of warmth and comfort.

Cool, thank you! I'm very tempted to switch; just was afraid losing the alu foil would be a poor choice. But the "eggshell" air pockets I guess might help in that department. I usually roll my fake Tempur pillow into the classic one though; will have to find another way of squishing that along somewhere ...
