Ultralight XR Insulated Air Sleeping Pad

I have ordered and received new StoS Ultralight XR Insulated Air for $111.45, still can return it. And then in some youtube review find out that people really like Naturehike Ultralight Insulated. Ordered mummy version for $89., will receive tomorrow. I need them for a broad general usage, mostly in the Rockies at the heights from 5000 to 12000 ft April to November, but hopefully also in some places like JMT. I am 5'11 side sleeper but can sleep on the back sometime if needed, and I am normally warm sleeper, however I have lost a lot of weight so not sure now. Really tough choice for me. StS one is 415 g, R 3.6. Naturehike on is 500 g, R 5.8. R 3.6 seems to be not really enough for a safe wide usage 3 season with quilt. 5.8 should be OK even for the mild winter conditions paired with 20 F bag. Weight difference is not that great from my point of view, price difference is also negligeable. But.. But... What do you say? Is StS Ultralight XR Insulated Air warm enough? Any personal experiences with one of them? My first personal impression from Ultralight XR Insulated Air is that is is probably comfortable for me to lay on the side, and that packing it back to it's original bag is really hard, I hate these super-small bags coming with all outdoor equipment. Edit: looks like StS one is thicker by specs, and people complain that Natiurehike one is on a thinner side for this R rating so harder for a side sleepers.

Thank you! Now seing them both by my own eyes I am inclined to keep StS. Pad seems to be the most technplogically advanced thing in my gear and StS just feels more up to the task. Naturehike is also great, just not on that level of rocket science.

>The naturehike is 2.75" thick while the sea to summit ultralight pad you mentioned is 2" thick.  Specs say 3.2 and 2.6 in thickness. StS is surprisingly comfortable when I try it in home. But the difference is here for sure. What is interesting the real weight difference is 150+ grams - StS bag is very lightweight, Naturehike bag is huge and heavy. And the pad itself not 500 g but more like 520 g. >April to November in the Rocky Mountains can mean almost anything Yes. It's hard for me to narrow it down. But I am living here, in Alta, UT and simply will not hike when it is too cold for whatever I am using. >I would consider options from manufacturers who make decently warm pads  That's a great universal advice, but it means +$100. I am still thinking about it, maybe I need to do it. But right now I am still not sure how seriously I will be backpacking this summer, and getting ideal pad for $220 - TRest XLight probably - would be wasting of $220 if it will sit in my closed. The moment I can realistically expect at least 10 backpacking nights in the next 12 month I will probably get the best available pad with R 4+ and thickness 3+. But then it would be a question do I need winter one...

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.

I bought one and I hate it.it sounds and feels like balloons rubbing together. I am a very active sleeper so maybe that’s why it sucks for me.

I’ve got one and have used it on a single overnight. Pros: \-Slightly more durable with 30/40d fabric \-Dimpled baffles are more comfortable for some folks \-Slightly wider (1.7”) in regular mummy \-Around $60 cheaper without sales \-Packs slightly smaller \-Much quieter than the NXT Cons: \-Only 2.6” thick versus 3” for the NXT. Bottoms out easily with point loads. \-Heavier than the NXT (1.6 oz) for regular mummy \-Not as warm (3.6R vs 4.5R) It’s a decent pad, but not revolutionary or anything. I like the price, extra durability, width, and quietness, but I don’t know how well it would work for a heavier person. It bottoms out pretty easily compared to the NXT. The dimpled baffles work well when you’re lying flat on it, but it just feels super thin.

I have the regular version of the NXT. I honestly haven’t decided yet. The extra width on the XR is what is making it difficult to pick a favorite. It doesn’t sound like much, but the extra almost 2” is nice. If I had the regular/wide NXT, I’d probably lean that way. Slightly less durable, noisier, but feels much more substantial due to the extra thickness and it‘s 25” wide for an extra 2 oz.

It's comfortable, but delicate. I had a rectangular one in medium and had a couple of unexplained punctures and a baffle tear. Exped was great with replacing it, but I didn't trust it. I think 20D is borderline for the bottom of a pad. NXT with 30d is a good balance between weight and durability.

Since you mentioned below that you have issues with your arms falling asleep, I'd experiment with some different sleeping pads. Lots of folks complain that horizontal baffles are less supportive at the edges and lead to falling off the pad or their arms going numb. I'd try out some lightweight pads with different baffle styles (dimpled and longitudinal). Maybe the Exped 1R/3R and the S2S Ultralight XR/Ultralight Air. If you have an REI nearby, it would be easy to experiment and return whatever doesn't work out. Are the inflatable pillows uncomfortable due to height issues, or just the feel? Maybe a hybrid approach like this: [https://www.youtube.com/watch?v=c-QGaNQHMZY](https://www.youtube.com/watch?v=c-QGaNQHMZY) I love mine. It's soft, supportive, light, and stays put on the S2S pillow lock patches. Best of luck.

\[I don't race\] My go to is StS UL Insulated which isn't as light as TaR ones, but the insulation greatly reduces the convection losses that are present in pads which rely only on mylar walls within the pad. Few years in and still no sign of wear nor leaks on the welds. Do you use quilt or a bag? If the latter, then maybe give a try to the Klymit Inertia X-Lite + current foam?

Check out the StS pads with that 'dotted' welding pattern. IMHO cracks showing up in the fatigued welds are more likely to be an issue rather than some punctures (unless you are really unlucky in some thron country).

I was like OP and had the Klymit but then switched to the Sea to Summit ultralight insulated pad (oval shape) a year ago and it’s been amazing. I used my Klymit again last month on a father-son trip and the difference in comfort is noticeable.

I’m 201 cm and have kind of resorted to just keeping my pack at the foot end to keep my feet of the ground. I have the old sea to summit ultralight insulated and find it very comfortable but a bit cold when close to freezing. For quilt I have Liteways sleeper quilt in the largest size and it works fine
