As I was loading my backpack at the start of a six-day, 74-mile backpacking trip in the Grand Canyon, I smiled as I held the stuffed Therm-a-Rest NeoAir UberLite air mattress in my hand; call me a gear geek, but unusually small ultralight backpacking gear just has that effect on me. One of my hiking mates glanced over and said, “Is that your air mattress?!” Yea, it’s that tiny. And if you’re serious about reducing your pack weight—as any backpacker should be—you should be taking a serious look at the NeoAir Uberlite. Here’s why.

I used the NeoAir UberLite on that Grand Canyon backpacking trip, when the coolest nights dropped to only around 50° F, and for a couple of nights camping in Idaho’s City of Rocks National Reserve, with a low temp in the high 30s, when I was warm enough pairing this air mat with a 32-degree bag (the Therm-a-Rest Hyperion 32).

With 2.5 inches of thickness, it delivers comfort comparable to many of the best backcountry air mats. I’ve found it comfortable either inflated to its maximum or to within one or two breaths of maximum inflation. In fact, on some nights when it lost a little inflation overnight—I suspect due to the air inside it cooling down, because there was no leak from the air mat—I didn’t notice it because my hipbones still didn’t hit hard ground when sleeping on my side.

At 8.8 oz. (without its included stuff sack), weighing 3.2 ounces less than the previous ultralight standard-bearer, Therm-a-Rest’s NeoAir XLite, it sets a new ultralight standard for air mattresses with enough insulation for camping in usual summer temperatures in the mountains (at mid-latitudes such as the U.S., most of Canada, and Europe), and it packs down smaller than a liter bottle at 6×3.5 ins./15x9cm.

With an R-value of 2.0, the UberLite won’t be quite as warm as the XLite (which has an R-value of 3.2), but it may be a little quieter.

One caveat: While all air mats are susceptible to suffering pinhole leaks that can be hard to find and patch in the field, the NeoAir Uberlite’s 15-denier nylon fabric is lighter than you’ll find in most air mats (including the 12-ounce Therm-a-Rest NeoAir XLite, which uses 30-denier fabric), so be careful with it. That said, over the course of five nights in the Grand Canyon—an environment notorious for needle-bearing vegetation and sharp rocks—the NeoAir Uberlite sprung no leaks.
