Although the NeoAir has been around for about a year-and-half, I don’t think enough of you know about The newer XTherm. Offering a R value of 5.7 it is the equivalent of stacking a Z-Lite and two standard military inflatable sleeping pads. All that at only 15 oz (430 g). Also, note it is available in four different lengths.

One important thing to note on the NeoAir is that it should be placed inside a sleeping bag. This not only increases comfort and insulation but also durability. Since it relies completely on air and a reflective material for insulation, it deflates much more quickly than foam lined pads and can be left inside your bag or bivy and stuffed for transport. The NeoAir does require a little more care than the standard pad but the advantages far outweigh the requirement to look after your kit.

Here you can see it paired with the UltraLite Cot which weighs just under 3 lbs.
