Our Take:
4.7/5
Editors' Pick
The Therm-a-Rest NeoAir XLite ($210) has paced the ultralight sleeping pad field for over a decade, and the current NXT version is one of our favorite mats on the market. We tested the XLite over four months thru-hiking the Continental Divide Trail, and it passed with flying colors: Its superb weight-to-warmth ratio was ideal for three-season conditions, and it proved surprisingly durable over the long haul. The pad’s comfort level, while adequate, isn’t fantastic though, and the XLite is no longer the undisputed best pad you can buy.

Pros

Industry-leading warmth-to-weight ratio makes it a favorite among ultralight backpackers.
Surprisingly durable for its weight thanks to 30D fabric and reliable valve design.
Not as noisy as past versions.

Cons

Expensive.
So-so comfort and support due to its horizontal baffling.
Pump sack is less user-friendly than competitors'.

For all of the superlatives that are heaped onto this pad, comfort might actually be the NeoAir XLite’s weakest attribute. I’m not saying that it feels like sleeping on cardboard; the NeoAir’s 3 inches of thickness is average for the air pad category and impressive considering it weighs a scant 13 ounces. In fact, I found it plenty comfortable on my Continental Divide Trail thru-hike, during which the NeoAir XLite helped me sleep soundly on uneven and rocky terrain. It was hard to bottom out on the pad while I moved around, and the new NXT version of the pad is much quieter than previous iterations of the NeoAir XLite, which were maligned for their crinkliness. Therm-a-Rest claims that its designers made the NXT 83% less noisy, and I’m inclined to believe them. It isn’t silent, but the volume is noticeably reduced and much more in line with the backpacking pad market.


However, other Better Trail members have taken issue with the NeoAir XLite’s horizontal baffles, which lag behind competitors in terms of design and stability. Because the pad lacks side rails or a slight curvature in the middle, sleepers are more liable to slide around—and possibly slip off—than they are on pads with vertical or box-shaped baffles. Competitors such as the Nemo Tensor All-Season, with its box-shaped baffles and 3.5-inch thickness, and the Big Agnes Rapide SL Insulated, which has 4.25-inch-thick side rails and segmented vertical baffles, do a better job at keeping campers centered and feel more plush to boot. Again, the Therm-a-Rest NeoAir XLite NXT is adequately comfortable; it’s just not a class leader.  

The NeoAir XLite is among the lightest air pads Better Trail has tested, and yet it’s one of the warmest three-season pads available. Its R-value is a very respectable (and, when considering its weight, impressive) 4.5, making it insulated enough that I was hardly ever cold on my CDT hike when using the NeoAir in combination with a 15-degree Katabatic Sawatch quilt. I even stayed perfectly warm while in the high country of the Colorado San Juans in early October, where I woke up on several mornings to partially frozen water bottles. I switched back to my old Therm-a-Rest Uberlite (R-value 2.3, 8.8 oz.) for the final two weeks of the CDT while trying to shed weight for the ultimate push to Mexico, and I immediately noticed a difference in warmth the next time it froze at night. 


While it's plenty warm for any three-season backpacking adventure you can draw up, the NeoAir XLite has some stiff competition in this space. The Tensor All-Season weighs only 4 ounces more than the NeoAir but has an R-value of 5.4, making it insulated enough to push into winter use (if mild winter conditions at that). That’s a fairly small weight penalty for a large jump in warmth, and the Tensor’s versatility as a four-season pad is a major reason to consider it as an alternative to the NeoAir. But if you plan to stick to spring-through-fall backpacking, this pad will be plenty cozy. 

In its regular size, the mummy-shaped NeoAir XLite packs down to 9 inches long by 4.1 inches wide, which—as with its weight—is admirable for a pad with this high level of warmth and adequate comfort. For comparison, the Tensor All-Season measures 10 inches by 4 inches in its stuff sack; the Big Agnes Rapide SL Insulated is even more compact at 7 inches by 4 inches. While the latter pad is the leader in this category in terms of well-insulated three-season models, the NeoAir XLite is still very, very packable; it’s one of the main reasons the NeoAir remains a go-to for thru-hikers such as myself. 

With a top and base both made out of 30-denier nylon, the NeoAir XLite is right in line with most ultralight air pads, which usually fall within the 20D to 40D range. While the fabric might seem thin compared to most backpacking gear—I would only use this pad in my tent or with a groundsheet—the material has largely held up over 2,000 miles of hiking, which is pretty dang good. 


The only issue I experienced occurred in New Mexico when I was on the CDT; some tiny holes appeared in the deep creases where the pad tapers into the inflation valve. I was able to patch the leak with some super glue and Tenacious Tape, and besides that the NeoAir XLite hasn’t failed at all. (I’ve even slept with it directly on lean-to floors on the Appalachian Trail.) The valve itself actually feels pretty robust, and I’ve never had the mechanism itself be the cause of any problems. I’ve probably put more miles on this pad than the vast majority of hikers will, and even though it costs $210 I’d say the Therm-a-Rest NeoAir XLite NXT presents great value and longevity for the price.

The NeoAir XLite comes with an inflation bag, which I found takes about 10 to 12 bag-fulls of air to fill the pad. That’s honestly not much faster than filling it with your lungs, but at least you won’t get lightheaded. Compared to pump sacks from other brands, I’d say it’s below-average in terms of design; It’s pretty finicky to attach to the valve opening, requiring perfect alignment and more pressure than I’d like to use on my $200 dollar backpacking sleeping pad. I prefer Nemo’s included pump sack a lot more, as it attaches and fills the pad quickly thanks to a long, narrow shape that makes it easier to capture and push in air.


The valve Therm-a-Rest uses is a unique design that features a twisting nozzle for one-way inflation and two white tabs that, when twisted along with the nozzle, allows air to flow out. It’s easy to use for inflation and it sits out of the way on the corner of the pad instead of on the sleeping surface, but it's slower to deflate than valves that can be popped all the way open. When packing the pad up in the morning, I sometimes had to roll the pad twice just to get enough air out of it to store it.

Longevity

Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.

The Therm-a-Rest NeoAir XLite NXT is available in four sizes: regular short, regular, regular wide, and large. All versions only come in mummy shape, meaning that they’re widest at the torso and taper down towards the legs. While this saves some ounces and bulk, it decreases overall sleeping area; many of the NeoAir’s competitors come in more spacious rectangular versions. 


On my CDT hike I opted for the wide version, which measures 25 inches wide (5 inches wider than the regular NeoAir). I thought that the extra five inches made a big difference when paired with my quilt—I was able to sleep in a more relaxed position when laying on my back thanks to the extra room. The wide version is 3 ounces heavier and a little bit pricier, and folks with narrow mummy bags or hikers trying to shave every ounce should still be fine with the 20-inch regular width.

Nemo Tensor All-Season ($200): Year-Round Warmth, Even More Comfort
Weighing just a smidge more than the NeoAir XLite, the Tensor All-Season (14.1 oz.) is the pad for backpackers who want to keep weight down but also extend hiking season year-round. Its 5.4 R-value is plenty for mild to moderate winter conditions; with the right sleeping bag, the Tensor should keep you cozy in temps down to the mid-20s or so. While heavier than the NeoAir XLite, the Tensor’s weight and packed size (10 x 4 in.) make it a good fit for a warm-weather kit. It also has a more comfortable design: Its box baffles cradle sleepers better, and it’s half an inch thicker. Factor in its decent durability, and the Tensor All-Season should be just as good a pick—perhaps better—than the NeoAir XLite, unless weight is your ultimate decider. For more, read our review of the Nemo Tensor All-Season.   


Big Agnes Rapide SL Insulated ($170): Comparable Performance on a Budget
The big difference between these sleeping pads is the price. But the Rapide SL is no cheap consolation prize: It weighs a mere 1 pound 2 ounces in its regular (rectangular) version, making it light enough for most backpackers, and its 4.8 R-value is a touch better than the NeoAir XLite’s. Like the Tensor All-Season, the Rapide SL is 3.5 inches thick and thus better for side-sleepers, and it adds 4.25-inch-thick side rails that protect you from sliding off the pad, along with softer, quieter materials. With two valves, the Rapide SL is a bit easier to adjust, though that adds an additional failure point compared to the one-valve NeoAir. And it lags behind in user-friendliness: We struggled mightily to pack this pad into its stuff sack, which is a bummer when breaking down camp. Still, this pad presents fantastic value.

A thru-hiker’s dream, this top-shelf pad boasts fantastic warmth for just 13 ounces. The NeoAir XLite NXT is versatile, easy to inflate, and less noisy than its predecessor. Comfort is the only area where it doesn’t excel.

We think the Nemo Tensor All-Season is the best all-around backpacking pad on the market. It lies at a near-perfect nexus of weight, cushion, and warmth. However, it’s a bit too heavy for militant ounce-counters.

The Rapide SL Insulated proves that standout comfort doesn’t always need a big price tag to match. This pad’s cushion, warmth, and weight should make it appealing for a wide variety of backpackers, although we’d prefer a larger stuff sack.

Is the NeoAir XLite NXT for You?

If money is no object, the Therm-a-Rest NeoAir XLite NXT should be on the (very) short list for backpackers who want a pad that will keep them warm through hiking season while also making space for carrying extra snacks. (Or, if you want to get more serious, who want to tackle a long trail without compromising too much on insulation or comfort.) While sleeping pads such as the Nemo Tensor All-Season and the Big Agnes Rapide SL offer better warmth and perhaps a more luxe feel for less cash, that’s not throwing shade on the NeoAir’s performance. Unless you want to maximize cushion or sleep on snow, you won’t regret purchasing this pad.
