Never get those cold night shivers again with the Thermarest NeoAir XTherm NXT & XTherm NXT MAX. With cutting edge Triangular Core Matrix™ construction and ThermaCapture™ technology, the XTherm NXT delivers a 7.3 R-value while weighing just 440 g (15.5 oz) in the Regular size. Put another way, the best warmth-to-weight ratio of any sleeping pad ever created. It is warmer and thicker than the previous model, which is why the XTherm NXT cements the legacy of being the go-to sleeping pad for alpinists, mountaineers and extreme cold expeditions. At 3-inches thick, with horizontal baffles, all-night comfort and support are at hand, while 70D nylon on the bottom ensures the XTherm NXT holds up to extended expedition use. The WingLock™ Valve allows for rapid inflation and deflation but is also intuitive and easy to use in frigid weather when the gloves are not coming off. If reliable overnight warmth is the demand no matter how far the mercury dips and space in the pack is at a premium, there’s no finer sleeping pad than the XTherm NXT.

  • Best Warmth-to-Weight Ratio Ever: Refined  construction and  technology deliver a cold-conquering 7.3 R-Value while a Regular size weighs just 15.5 oz (440 g).
  • Premium Comfort: A 3-inch (7.6 cm) thick profile and horizontal baffled structure delivers premium backcountry comfort while keeping the weight to a minimum.
  • Ultralight Durability: 70D nylon on the bottom withstands the wear and tear of extended expedition use, while 30D ripstop nylon on top keeps it light and packable.
    •  Delivers fast one-way inflation and rapid deflation without giving up the ability to easily purge air while you lay on it for comfort micro-adjustments—even with gloves on.
    • Multiple Sizes: 3 size options allow you to get the XTherm NXT that is perfect for your sleep system.

Pump sack, stuff sack and field repair kit included.

Great sleeping mat

Bought XTherm NXT because my current mat had a low R-value and was not warm enough on cold nights. The new Thermarest XTherm NXT performed well on a recent 3 day hike into the Kosciuszko National Park. All three nights were below zero temps, the coldest being around -7C. Combined with a good sleeping bag, I was warm and comfortable. The NXT packs down to a reasonable size and the stuff sack is big enough that you don't need to be overly careful how you roll the mat to get it back into the bag, including the pump sack. The pump sack was a great addition and, while it take longer to inflate, it's far more relaxing than blowing a mat up.

I'd advise keeping the mat slightly under inflated when you go to bed because your body temp will raise the pressure in the night and the mat pressure will increase. It's not hard to release a bit of air if you need to but better to avoid the problem in the first place. The XTherm NXT is a good thickness and keeps you off the ground even if you like a slightly softer inflation like I do. the mat is a bit noisy when you roll over but it is not noisy for small movements.

I am 183cm tall and bought the large version. Combined with the extra width of the large, I did not have to worry about rolling around in the night and staying on the mat. The extra room was worth extra weight in my opinion. If you're less than 183cm, consider the regular or regular wide version.
