Part of the reason it took me so long (2 years) to allow myself to go with an inflatable sleeping pad is because I’m always terrified I’ll puncture it and end up sleeping on the ground for an extended period of time. So far, the Thermarest NeoAir Xtherm has not disappointed in terms of reliability and durability. The 70D Nylon is particularly durable.

While the R-value of the XTherm NXT increased from 6.9 to 7.3, again, that’s not a good enough reason in my opinion to upgrade to the XTherm NXT if you already own an older XTherm. Anything over an R-value of 6 is already going to be overkill in terms of insulation performance in winter in the lower 48. To be honest, I suspect the R-value increase in the XTherm NXT is tied to the increase in pad height, rather than being a deliberate improvement. The increase in air volume probably makes the pad warmer. QuieterBoasting the most warmth per gram for an ultra lightweight mattress, the Thermarest NeoAir XTherm is trusted by mountaineers worldwide. The NeoAir XLiteNXTis available in sizes:Regular Short, Regular, Regular Wide, Large, MAX Regular Wide and MAX Large Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix construction and ThermaCapture technology deliver a cold-conquering 7.3 R-Value while cutting over 1 oz (28 g) in weight from the previous model. Ultralight: 439 g (regular) means warmth without the weight typically needed to stay warm in frigid conditions

I had the opportunity to test the NeoAir Xtherm near the Great Sand Dune National Park in Colorado. I was a little bit worried that I’d turn into an ice cube overnight while camping near the Sand Dunes. It wouldn’t be the first time. But it actually took no time at all for the Xtherm to insulate my underside despite some pretty chilly temps. Please note that inflatables such as sleeping mats are not considered as faulty if they become punctured during use and are not covered by the manufacturer's warranty in this event. Durable: 70D Nylon fabric bottom resists punctures and delivers a pad that can be confidently and extensively used in the rugged hills and mountains.

The mat has an incredibly hight R-value of 7.3, this is a mat that can be used in arctic conditions, and weighs only 694 grams, truly impressive. Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix construction and ThermaCapture technology deliver a cold-conquering 7. R-Value while cutting over 2 oz (57 g) in weight from the previous model.

The Thermarest NeoAir Xtherm does a terrific job of retaining heat. Pretty much all of the mainstream gear testers have showered the Xtherm with rewards for the duration of its life. Overall, reviewers have given the Xtherm a 4.7 star rating. Pros: The Xtherm has the highest R-value to weight ratio in the world. This means that you cannot find a sleeping pad that is as warm as and weighs as little as the Xtherm. The fabric: While the Xlite is made out of 30D rip HT Nylon, the Xtherm is made out of 30D rip HT Nylon on the top and 70D nylon. The 70D nylon makes the difference in both weight and R-Value capacity, making the Xtherm the best 4-season sleeping pad on the market. Thermarest Xtherm Weight Efficiency:

This mat has a R-Value of 5.7 which in real terms relates to true 4 season performance, so it is perfectly suitable for use on snow or frozen ground. R-Values are an international standard of insulation and (in simple terms) indicate the materials ability to reduce heat flow through conduction, radiation or convection. Therefore the higher the R-Value, the lower the heat transfer and the greater the insulation properties of the material. It took sleeping in the snow-covered San Juansfor a week for me to realize that your sleep system isn’t just about your sleeping bag. It’s called a “system” for a reason. I carried a 0-degree quilt and a very well-loved Thermarest Z-lite Sol for the duration of the Colorado Trail. Most of the time, I slept alright on the Z-lite. But my last couple weeks brought a bunch of snow. And I pushed my sleep system to its breaking point.When the ground froze, I could feel the temperature through my sleeping pad. I probably should have retired the Z-lite Sol after the Appalachian Trail but I like pushing gear to its limit. Sleeping Pad R-Value: You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat. From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

Sleep comfort is SO important while you’re putting yourself through an extended hike. If you’re not sleeping well, you probably won’t hike well. And your sleeping pad is one of the biggest parts of your sleeping experience, so it’s important to get it right and choose wisely. Sleeping Pad Reliability and Durability: Unmatched Warmth-to-Weight: Patent-pending, reflective ThermaCapture™ technology traps radiant heat while Triangular Core Matrix™ construction minimizes convective heat loss–all without the bulk, weight or durability issues of down and synthetic fills. Important things to take into consideration: Any time you’re sleeping on an inflatable air mattress, it’s really important to adjust the air volume to adapt to the expected air temperature. Meaning that when it’s cold outside, the air in your mattress will compress. And when it’s warm, it’ll inflate.
