Should You Buy The Therm-a-Rest NeoAir XTherm NXT?

Any customer information held on our computers complies with the rules and laws contained within the Data Protection Act 2018. 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.

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: The unrivalled Triangular Core Matrix offers the best warmth-to-weight ratio of any air sleeping pad construction. When comparing the Neoair Xlite vs Xtherm in size terms there are a few differences. The Xlite comes in Small, Regular, and Large. While the Xtherm only comes in Regular and Large. However, this actually makes sense for a winter product and you’ll more than likely want to opt for this Neoair Xtherm large if you’re cold weather camping. Durable: 70D Nylon fabric bottom resists punctures and delivers a pad that can be confidently and extensively used in the rugged hills and mountains.An important part of this Neo Air Xtherm review is to actually consider your personal needs rather than jsut the specs of the prouct. Things to consider:

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. Quieter 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.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. 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: To enhance the comfort and versatility of thesemattresses even further,similar to the current XThermMAX, for 2023, both the XLite and XTherm NXT willbe available in the existing mummy shape andamorespacious rectangularshape, perfect forthoseseekinga little extra comfort and spacewhile they sleep. Boasting the most warmth per gram for an ultra lightweight mattress, the Thermarest NeoAir XTherm is trusted by mountaineers worldwide. And Thermarest is known for having really terrific customer service, so at the very least, they’ll probably fix whatever problems you might encounter.
