Weighing simply 16 oz, the XTherm NXT can also be light-weight, rolls up small, and is made with thick and sturdy supplies, together with a 30d prime material and a 70d backside material. Weighing solely 16 oz, the brand new NeoAir XTherm NXT has an astonishingly excessive R-value of seven.3 which is considerably greater than the minimal R-Worth of 5 that I like to recommend for winter tenting and backpacking on snow. Many individuals underestimate the significance of their sleeping pad of their sleep system and if you happen to discover you’re nonetheless chilly with sufficient insulation topside, your pad could be the perpetrator.
The NeoAir Insulation System

The Therm-a-Relaxation NeoAir XTherm NXT is designed to lure your physique warmth and mirror it again at you while you sleep at evening. Not like sleeping pads containing down or artificial insulation, the XTherm NXT achieves this utilizing a honeycombed development of air baffles which might be lined with a reflective metallic coating. The result’s a really skinny and light-weight air mattress that rolls as much as the scale of a Nalgene bottle, making it very simple to pack. The identical honeycombed baffles are utilized in the entire NeoAir pads that Therm-a-Relaxation makes, though it offers NeoAir pads a crinkly potato-chip-like sound that many individuals discover disturbing at evening. Extra on this, under.
Valve and Pumpsack
The XTherm NXT makes use of a WingLock valve, first launched in 2020, which helps you to quickly deflate the pad, inflate it by mouth or with the included pump sack. The pump sack is price utilizing in winter to keep away from blowing moisture into the pad by mouth that can freeze within the valve or insulation chambers in a single day. The pump sack, which is principally a big stuff sack with a valve at one finish, also can double as a protecting stuff sack for the sleeping pad.

What’s New within the XTherm NXT?
The NeoAir XTherm NXT is thicker, hotter, and quieter than its predecessor, the NeoAir XTherm inflatable sleeping pad.
Thickness
Thicker inflatable sleeping pads have grow to be more and more widespread in recent times as a result of they’re way more snug to sleep on. Whereas rising the XTherm NXT to three″ thick from 2.5″ supplies a slight enchancment in consolation, I feel the principle cause Therm-a-Relaxation elevated the pad’s thickness was for aggressive causes. The most effective inflatable sleeping pads out there right this moment are not less than 3″ thick, with some as thick as 4″ just like the Sea-to-Summit Etherlight XT Sleeping Pad. Nevertheless, if you happen to already personal an outdated 2.5″ XTherm sleeping pad, it’s fairly troublesome to note any vital enchancment in consolation and I wouldn’t improve primarily based on this cause alone.
Regardless of being 3″ thick, the XTherm NXT isn’t as snug as pads which have vertical baffles or ones which might be formed extra like mattress springs and conform to your physique. The XTherm NXT isn’t horrible, but it surely’s not essentially the most snug pad. Nevertheless, you can also make the XTherm NXT extra snug by letting some air out of it, though this may cut back its insulation worth considerably.
R-Worth
Whereas the R-value of the XTherm NXT elevated from 6.9 to 7.3, once more, that’s not a adequate cause in my view to improve to the XTherm NXT if you happen to already personal an older XTherm. Something over an R-value of 6 is already going to be overkill by way of insulation efficiency in winter within the decrease 48. To be trustworthy, I believe the R-value improve within the XTherm NXT is tied to the rise in pad top, reasonably than being a deliberate enchancment. The rise in air quantity most likely makes the pad hotter.
Quieter
Therm-a-Relaxation claims that the XTherm NXT is roughly 80% quieter than the outdated XTherm. Having slept on the NXT, I concur. It’s noticeably quieter while you’re mendacity on prime of a totally inflated NXT. However the pad continues to be extremely loud, like smashing potato chips, while you’re within the strategy of inflating it or rolling it as much as pack it away. In the event you attempt doing these in an Appalachian Path lean-to early within the morning or while you arrive after darkish, you’ll most likely get shot. Till the noise of inflation, deflation, and packing is decreased, I can’t see a robust rationale for upgrading from an outdated XTherm on the idea of sound discount, though your tent accomplice would possibly beg to vary.
Many individuals don’t care that a lot concerning the noisiness of the NeoAir sleeping pads, myself included as a result of I often camp far sufficient from different those that they’re unaffected by my sleeping pad sounds. I’m additionally often so drained that the noise of the pad gained’t wake me.

NeoAir XTherm NXT Max
The NeoAir XTherm NXT reviewed above is just out there in a tapered mummy form. In the event you want a rectangular-shaped sleeping pad, there may be one known as the NeoAir XTherm NXT Max, which has the identical R-value (7.3) as the mum model. The XTherm NXT Max is on the market in two sizes, a daily (72″ x 25″) and an extended (77″ x 25″). Each are additionally 3″ thick.

Suggestion
The Therm-a-Relaxation XTherm NXT Sleeping Pad continues to be a dependable, sturdy, light-weight, and high-R-value sleeping pad good for chilly climate use despite the fact that the enhancements to the brand new mannequin are a bit underwhelming. In the event you’re a chilly sleeper otherwise you need a extra sturdy pad for higher-risk winter use, the XTherm NXT Sleeping Pad nonetheless supplies lots of worth. It’s simply not as aggressive because it was once by way of weight, consolation, packability, and ease of use. If you’re searching for a great deal on a winter sleeping pad, it is a good time to choose up an older mannequin XTherm at a big low cost.
