The NeoAir XTherm NXT Sleeping Pad is the best warmth-to-weight ratio of any sleeping pad ever made. With cutting edge Triangular Core Matrix™ construction and ThermaCapture™ technology, the XTherm NXT delivers a 7.3 R-value while weighing just 439 g.

The NeoAir XTherm NXT is warmer, lighter and thicker than the previous model, which is why it cements the legacy of being the go-to sleeping pad for alpinists, mountaineers and extreme cold expeditions. At 7.6 cm thick, with horizontal baffles, premium, all-night comfort and support are at hand. This ultralight, durable mattress benefits from 70D nylon on the bottom to withstand the wear and tear of extended expedition use, while 30D ripstop nylon on top keeps it light and packable.

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.

  It is a long time since I last backpacked and camped, last time was pre children and I’m now approaching retirement so I was a bit apprehensive and I have got used to good hotel beds. I am delighted to say this mattress far exceeded my expectations in terms of comfort and I can’t fault it. Also, it packs remarkably small and light but everyone knows that. I had a slight glitch and had to contact customer services, I would give them 6 stars. This is an absolutely excellent company to deal with and I can’t recommend them highly enough.

  I was previously using an Exped Downmat UL Winter model but wanted an alternative mat that packs smaller, lighter but retaining the high R value for winter use. This is perfect. Seems more durable too with the bottom of the mat being a more sturdy material. Looking forward to heading out on winter camps with lighter gear, smaller rucksack and still staying snug and warm at night.

  Had this product for over a year now, fantastic bit of kit, was camping out early this year (2019) in a hammock in minus 3 and every time I turned on my side my back got cold, as soon as I lay on my back within seconds I could feel the heat radiate back to me warming my back. You get what you pay for and will definitely increase your ability to keep warm and comfortable.

  Dear Woodlore, you are just a wonderful website and company. The goods I purchased from you arrived safely and on time, and are very good. In relation to the Therm-A-Rest NeoAir sleeping mattress, I can share that I have just tested it so far at home and I am looking forward to testing it next week in the mountains. But it looks like a really wonderful product. It is light, but also comfortable and well insulating. It's really the best I could find given its product features. So thank you again for your service.
