Ultralight and warm, the Therm-a-Rest NeoAir XTherm NXT sleeping pad is highly durable and boasts a 7.3 R value, giving it a warmth-to-weight ratio suited for extremely cold backcountry pursuits.
With cutting edge Triangular Core Matrix™ construction and ThermaCapture™ technology, the XTherm NXT delivers a 7.3 R-value while weighing just 15.5 oz (440 g) in the Regular size. Put another way, the best warmth-to-weight ratio of any sleeping pad ever created. It’s 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 Triangular Core Matrix™ construction and ThermaCapture™ 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.
WingLock™ Valve: 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.

Guide Pick
"I trust the neo air xtherm to keep me warm and provide a soft sleeping surface for needed recovery while climbing."
The guides over at RMI collectively spend over 10,000+ days a year on the world's highest mountains, climbing hundreds of thousands of vertical feet. They put their gear and apparel through the wringer. This stuff is their work wear and they simply will not tolerate inferior gear.
Step 2
At the end of the climbing season, guides are given a survey to find out what gear they are using and why it is their favorite. We don’t often get complete agreement but we do get alignment and by looking at the data, a few clear winners rise to the top in each category.
Step 3
We take those winners, and stamp them with the Guide Pick™ logo on our site. We also compile this wonderful little document, which you can use to see top contenders, gear advice, Guide Quotes, and more.
This pad did exactly what I expected on a ski mountaineering trip to the top of Mt. Baker this weekend. Stayed consistently inflated all night (unlike the pad I was replacing), did not sound like I was lying on a bag of chips (like my other neo air), and kept me cozy in my bivy bag. It was the pad’s maiden voyage, but it was one of the best nights sleep in the alpine in the last few years!
