Well you didn't mention seasonality, comfort, or size, but closed cell foam (e.g. nemo switchback; thermarest z lite sol) fits your desire for durability and weight
Could you try a Zlite and two 1/8" thinlight pads? They are evazote, I believe. You could fold one up and use it as a back panel and roll the other like a newspaper. It can tuck away in the large front pocket of your pack or water bottle pocket. Together, they would add about 1 R value. I'm not certain that would get you from 35 to 25 degrees. But the bulk would be a lot less than 2 ccf pads.
wondering how often you slept in a shelter vs sleeping in your tent?
I personally used to love CCF pads but have found them not to work on the hard shelter floors. I switched to an airpad for my thru since I planned on sleeping in shelters more often than not. I really enjoyed my airpad, but will still use my Zlite Sol when just doing short overnighters now
I ordered both mats, the ZLite SOL and the Yamatomichi UL Pad 15+, both in the short one-meter version. After trying them on the floor at home, I honestly couldn’t feel any real difference in comfort.
The main advantage of the UL Pad 15+ is the weight. It’s about 70-90 grams lighter at the same length, which is a nice bonus if you’re counting grams. The downside is packing it, because it doesn’t fold nearly as well as a ZLite or a Switchback. What works okay for now is using it as a tube inside the backpack and packing everything else inside that tube. It gives the pack a bit of structure, but I’ll only know how practical it really is once I have all my gear together for the trip. That’s when I’ll see whether the ZLite packs better overall or whether the Yamatomichi tube system ends up being good enough. In the end I’ll go with whichever option integrates better inside the pack, since attaching a pad on the outside isn’t really an option for me at the moment.
In terms of comfort they feel very similar to me. The UL Pad wins on weight and the ZLite wins on packability
There are a lot of ultralight hikers who sleep solely on a CCF (closed cell foam) pad like a Z-Lite or Switchback. Foam is the original ultralight choice. If noise is an issue, foam doesn’t make not like many inflatable pads.

Car camping comfort champ, but some side sleepers find it thin.
