NeoAir UberLite

There was a recent discussion about this type of pad and it’s R values here: https://www.reddit.com/r/CampingGear/s/AcsRlx09DN I use those olive green military surplus Thermarest ultralite pads for car camping with achesp closed cell foam pad underneath for my kids. I usually use something beefier for me. The pads can be found online and budget prices (~$15 new old stock), but shipping $$ will get you. It’s a good budget combo For backpacking, I prefer the lighter weight closed cell foam pads in conjunction with a newer version of inflatable pad like the Xtherm or in summer the Neo air Uber light.

Plenty of brands use 20D, the few times they've ventured lower has massively impacted durability; see the thermarest uberlite and the current Nemo tensor elite, which Nemo even admitted developed pin holes during testing. You will be fine with 20D with or without CCF underneath. I use an X-lite which is 30D I believe but previous mats I've used were 20D all fine and I'm don't exactly baby my gear lol.

Maybe I’m in the lucky minority but I’ve had a thermarest uberlite that has lasted me years without issue. It’s my primary pad and all I do is make sure I clear out any pokey objects from my campsite before putting my tent up. I’d guess I have 60+ nights on it at least.

I think further reductions in weight of inflatable sleeping pads will require new materials. The Uberlite shows that we already reached beyond the limits of current materials and need to step back.

At some point I stopped counting grams and just decided I'm brining the Regular Wide ThermARest XLite. The wide is key for a slide sleeper like me. The uberlite was amazing for saving weight and still having the size but sadly like most folks uberlites a micro hole put it out of commission. Recovery/Sleep is more important than slight amounts of weight.
