Therm-a-Rest NeoAir XLite NXT MAX Regular Wide

XLite NXT is the latest version of the highly popular, and likely the most common mattress choice among ultralight hikers. The key parameter for the XLite NXT is its R-value, which is 4.5. This is remarkably high considering the weight of the mattress. It’s made possible by combining Therm-a-Rest’s patented Triangular Core Matrix™ construction with ThermaCapture™ heat radiation technology.

The inner workings of Xlite have been updated in the new NXT model, significantly reducing the familiar crinkling noise of previous versions. For some, this might be a bit disappointing, as that familiar chip-bag-like rustling had become synonymous with epic adventures. But maybe your hiking buddy in the same tent will see the brighter side!

The fabrics have been chosen with a focus on both lightness and durability, featuring 30D rip HT Nylon on both the top and bottom of the mattress. Along with the mattress itself, the package includes a storage bag, a pump sack, and a repair kit.

If you’re wondering which insulated mattress would best serve you on your three-season hikes in the Nordic region while remaining exceptionally lightweight, the Therm-a-Rest NeoAir XLite NXT is the top choice. It won’t leave you shivering even if the temperature dips a bit below freezing, which is quite possible in early and late summer.

MAX = Rectangular-shaped mattress

Regular Wide = Wide mattress with standard length

In addition to being warm and quiet, the XLite NXT in MAX size ensures great sleeping experience boasting a generous 63 cm width and a plush 7.6 cm thickness. Filling up the XLite NXT is a breeze thanks to the WingLock™ valve, which is intuitive, reliable, and maximizes airflow in both directions. The valve’s wings prevent air from escaping while you’re inflating it, which is quite a relief after a long day when all you want is a good night’s sleep.

The MAX Regular Wide size solves the typical issue with narrow sleeping mats – not enough sleeping surface area, which can be a bother for larger individuals or those who toss and turn in their sleep. This extra space might add a bit of weight for the weight-conscious hiker, but it pays off immediately after a good night’s sleep. You don’t have to decide whether to keep your knees or buttocks on the mattress while sleeping on your side, or lock your hands inside your clothes when lying on your back.

Our Tips:

• You can confidently leave the pump sack at home and inflate the XLite with your own lungs, as they’re with you on the trip anyway. Of course, puffing after a day’s hike might feel a bit taxing, in which case the pump sack justifies its place in your backpack and doubles as a stuff sack for clothing.
• Instead of rolling, try folding the mattress in a Z-fashion against the back panel of your backpack. You can tuck flat items like empty soft bottles or maps in the accordion folds for efficient use of space.
• For users of quilts, it’s a good idea to leave the attachment straps in place when packing the mattress in your backpack so they’re ready to go at the end of the day.
