NeoAir XLite NXT Sleeping Pad

I used Thermarest Neoair Xlite NXT in February and was warm enough (R4.5 - 2deg C in Sussex). So you probably don't need to worry about R factor.

+1 for lengthwise baffles and therefore Exped. I tried the Neo Air, I toss and turn a lot...I could only ever sleep comfortably on lengthwise baffles

You didn’t list the weights but the Neoair Xlite NXT weighs 12 oz, whereas the Nemo pad weighs 18 oz. That’s an enormous difference in UL terms. If those are the only choices, pick the Xlite. (All this assumes you are attempting to lower your baseweight to the minimum, else why ask on this subreddit?) You could then do what I did and shorten it to 3/4 length and use your backpack under your feet. That configuration is easier to adapt to than you think. That gets it close to 9 oz — half of the Nemo.

Therm-a-Rest NeoAir XLite with an r-value of 4.5 weighs 370g. You don’t need a stuff sack.

Have you looked at a Thermarest Xlite? Better warmth to weight than those options.

If you wanna make it even more lighter and packable, there’s a way to [shorten it](https://m.youtube.com/watch?v=90Fx6TLNEJQ) down to three-quarter length and use your backpack for the lower body insulation. That’s what I do. Mine weighs 270 g after the modification.

That’s old news. They’ve altered the way they make them so they are nowhere near as noisy anymore. They used to sound like crinkly paper when you turn. No longer.

Test both and then decide, because everyone has a different body. I personally switched from the Sea to Summit Ether Light XT Insulated (size L with similar baffle structure to the Tensor) to the Therm-a-Rest NeoAir XLite NXT (size RW). Both are wide, the NXT is just regular length and as a side sleeper, I’ll never go back. I think the crucial point is to inflate it to the right pressure because overinflation won’t be comfortable. My preferred pressure is when I sit on the pad I almost touch the ground, but when I lie down, it feels perfect.

I’ve got both and definitely prefer the S2S. The dimpled mat is somehow more comfortable the higher you inflate it. I found the Therm-a-rest louder and less comfortable.

Sleeping better is worth the additional 4.5 oz's all day long. Not every thing can be measured with weight. If you're more rested, an additional 8oz's is worth the tradeoff. More rested = more energy = more miles = more efficient = more happy. Stupid Light vs. Smart Light. Of course this all assumes you'll sleep better on the Tensor. I have both, but only just got the Tensor (25 x 72). I can tell you the NeoAir XLite NXT (20x72) isn't quite warm enough for me here in Montana's summer highcountry. I also dislike coming off it at night since it's so narrow. I'm migrating back to ccf pads or wider inflatables.

I've got a Thermarest NeoAir Xlite NXT Sleeping pad, and am a side sleeper  I find it's too slippery, ended up putting it inside my sleeping bag liner. I'm looking for something else, I think., let's put it like that. Anyway, I'm here to see of there's anything I can do to improve my sleep. I'm going to carry a folding thermal mat too, next trip, if I can deal with the bulk.
