Therm-a-Rest - NeoAir XLite NXT MAX Sleeping Pad

my partner is a very cold sleeper an got the Therm-a-rest Neoair Xlite NXT MAX 4,5 for a Norway trip. I´ve used the same pad. We had 11 days in the tent and we slept very well! never been cold. It packs small and is reasonably light.

I own an xlite large and an uberlite

The NXT xlites are much quieter...could not get a good night's sleep with the previous version. I have both the Nemo AS & latest xlite in wide...prefer the Nemo by a small margin (better comfort with small weight penalty).

I feel like my Therm-a-Rest NeoAir Xlite NXT (max) (I have the largest version of the regular model) and it feels very durable. So far it survived a 2 Bikepacking trips through Germany, cowboy camping and a festival. It's really thick so very comfy. It's also really warm. My model weights about 380g and very light.

I have the therm-a-resr neoair xlite nxt. It's light, small packaging size and incredibly good insulation.

6’4 240lbs here, side sleeper as well, I use the thermarest neo air xlite in size large. I know it’s over your budget but I have had mine for 7 years no issues, it packs up super small and is real lightweight.

It sounds like your pad is too narrow for you. I have the wide version of the Neoair Xlite and I sleep like a baby on it.

I have a Therm-a-Rest Neoair Xlite RW (440g) thermal air mattress and it is perfect. It’s easy to pack, well-designed, and very easy to inflate. I tested it in Germany back in the spring, and I didn’t feel cold at all. But I tested it in the shop. I highly recommend the test.

[here's](https://www.reddit.com/r/WildernessBackpacking/s/7vAF6wA3dd) some suggestions I made recently. None are UL really but neither is the pad you're coming from. Best bet is probably the Therm-a-Rest NeoAir Xlite in the usual mummy size for best/lightest in the segment. Exped Ultra 5R is fantastic but decidedly not UL

Do you have a max budget? Do you have a good sleeping bag to pair it with? Any of the modern inflatable pads will fit in your bag unless you've brought enough other stuff to cross the continent on foot, lol Here's our experiences, though not a comprehensive review of everything on the market. TLDR probably get you an Exped Ultra 5R. Nemo Tensor: I am a flopper and tended to roll onto the edges, which made them collapse and dumped me onto the ground. Pad is comfortable otherwise. It does make quite the crinkly sound when moving. Exped Ultra 3R: probably a bit cold when temps are approaching the lower end of your range. Large side baffles (like the Big Agnes you linked, I think) keeps you from flinging yourself off the pad. Thick and comfortable. Fantatsic pump sack inflates the thing in like 20 seconds. Was entirely too cold for us where it gets colder than your range. Side note, it was paired with a Big Agnes sleeping bag which was horrible. Terrible bag. Exped Ultra 5R: all the pros of the 3R but warm enough! Great pad, my wife's current go-to. Therm-a-Rest NeoAir XLite MAX: or whatever the yellow rectangle \~5R one is. Lacks the side bolsters of the Exped and is thinner, but is very comfortable and IIRC lighter. Another great pad, my current go-to. Pump sack is beyond useless, too porous and leaks air instead of blowing into pad. I just blow it up by mouth. Generally, I've found we prefer rectangular pads. If you're with someone else and you both have rectangular pads - make sure they fit in your tent! Many tents are tapered and your feet will overlap which is super annoying

I use the thermarest xlite nxt combined with the MLD thin light pad. I’ve used this combo down to around 5f and been toasty underneath. I tried the thin light pad underneath the inflatable and on top and found that it was warmer on top the inflatable. My biggest cold spots resulted from drafts around the sides of my quilt below 20f. This sounds weird but I tucked the thin light pad inside my quilt and it made a big difference in stoping drafts and my contact side was not cold. I’ve also slept in expedition grade down jacket and then down pants with alpha layers underneath and down booties with no sleeping bag and stayed warm on top the thermarest down to about 10f.

If your planning on sleeping with temps below 20f your going to want a R6 or greater insulated sleeping pad like the thermarest xtherm. I’d say the thin light pad is comfortable 30-20f on a r4 three season pad. You’ll defiantly want a 0f bag if it’s anywhere close to 0f no playing around when its that cold.. Long term temps below 10f makes for very difficult backpacking survival without a well planned gear kit. It’s hard enough to keep your water from freezing and the colder it gets the faster it all happens. If the ground is frozen and your on a r2 sleeping pad your ground side body will feel like it’s slightly warmer than freezing. You’ll be rolling over every 10 mins or less to keep the ground side of your body warm and it’s not fun. From r2 to r6 or above is a huge difference in Insulation when it’s below freezing.

I’ve got the thermarest xlite nxt and been comfortably warm to around 15f. That being said I believe the amount of air pressure in the pad can make a difference in comfort and warmth. I found the pad most comfortable slightly deflated. However, I believe you lose warmth with lower inflation psi, and max psi does feel warmer to me although like sleeping on a rock. Getting the sweet spot of perfect psi can be difficult and sometimes I fiddle around letting a tiny bit of air out until my shoulder stops falling asleep. Wish there was a UL psi gauge built into the pad. 🤣

For the sleeping bag I’d recommend a zpacks, timmermade or cumulus 30f range sleeping bag you could push into much colder temps wearing alpha 120 bottoms, down jacket, and down foot booties inside the sleeping bag. I’ve used this combo of clothing to push my 12oz 50f sleeping quilt down to 20f comfortably. If you plan to camp mostly in the summer I’d get the 50f bag and just wear more clothes inside it to push temps lower in fall. I switched to this technique and was able to reduce my pack size a lot and half the weight of my sleeping bag and its bulk. It works well since I’m already taking the alpha pants and down jacket anyways so I might as well wear them and save weight on the sleeping bag. The wind makes the biggest difference to me for how much insulation I need at night. For High Wind below freezing a windproof bivy that can fit over your pad and quilt makes a huge difference to your overall warmth and stoping drafts. Many UL quilts with 7D fabric are not very windproof and even a 20f bag can feel very cold at 20f in high winds. I like to summit camp and it’s often very windy above 6000ft. For the sleeping pad I’d recommend the thermarest nxt https://cascadedesigns.com/products/neoair-xlite-nxt-sleeping-pad?srsltid=AfmBOop1YJvl8n8oPU1vCNvveJ5sopEYhuUIcb1ORgJmz5-Sc-vxRd-W If 6.1 and the wide thermarest fits me but is still small. It packs down very small and is the most comfortable and insulated pad for the weight that I’ve tried yet. I have slept at 10f in the snow and been fine with it. You can also pair it with a gossamer gear thin light foam pad and gain more R values for freezing temps.

I have the NXT and it’s warm down to about 15f. I’ve found that if you pair the NXT with the GG thin light it adds insulation and can be pushed to single digits temps as a system. Then you don’t need a dedicated winter sleeping pad and you’ve got the GG thin light as a sit pad and yoga mat.

I’ve have a thermarest xlite nxt size wide but wish I had bought the uberlight because most of my camping is 3 season and it’s a good bit lighter. I’ve got around 85 nights on mine no leaks. I have washed it several times and it’s holding up great. Most of the time I set the pad on top of a MLD thin light pad which I also lay down around camp on, do yoga, or use it as a sitting pad. I am over 6 foot and a side sleeper and my feet and knees hang off a little bit on a size wide. I’ve tried some other sleeping pads, but they were not as comfortable although the tensor is about the same comfort if not a tiny more because I think it has better side stability.

You’re spending a lot of money so I definitely would test them. Also, you can get a less insulated pad and pair it with the MLD thin light and then use it over top, or underneath your sleeping pad to gain more insulation and push the pad beyond summer use. I use my xlite down to around 10F so far sleeping with MLD pad ontop of xlite. For three season use I sleep with the MLD pad underneath the X light just to prevent puncture, but that’s not the main reason I bring the MLD pad. I don’t take a chair so I really like to use it to lay on by the fire or use as a sit pad. It’s only 3.1oz and it has more function than buying the warmer xtherm as a dual use item that can also add insulation to your three season pad but be useful around camp… laying down yoga sitting etc.. or using the xlite outside the tent in the open ontop the MLD pad to prevent pops. In freezing temperatures I’ve tested the MLD below and on top the Xlite and found that it is way warmer on top.

Sea to Summit has a structure they call "air sprung cell". I personally own an old NeoAir but have tested a Sea to summit pad with that structure and I must say, it was much comfier. I've been trying to justify chucking in the money for a new pad, but am not there yet.

Check out airpads by Thermarest, Exped and Sea to Summit. Not the self-inflating ones, the ones with thick air chambers. They can be up to 4" thick, and the comfiest ones are miles away from a roll mat. If you buy one, don't inflate them by blowing, as exhaled air has enough moisture in it to cause issues down the line.
