The Nemo Astro Insulated used to win our Top Pick Award for Comfort, but the new Therm-a-Rest NeoAir Camper has replaced it as our favorite all-purpose pad for car camping and backpacking. The NeoAir Camper is more comfortable due to its flatter surface and lack of a built-in pillow. The Camper is also slightly lighter than an equivalent sized Astro or Nemo's larger sized Cosmo pad.

Check out our Backpacking Sleeping Pad Review to compare all of the models tested.

New Version Update - March 2015
The Astro Insulated is now available in two different sizes, the Astro Insulated 20R and the Astro Insulated 25L and in a new color! Keep reading for more details and look for a new review of this product in the beginning of August!

OutdoorGearLab Editors' Hands-on Review

The New Version of the Astro Insulated vs. The Older Version

See below for a quote regarding what Nemo has to say about the new versions of the Astro Insulated, which are now available in the Astro Insulated 20R and the Astro Insulated 25L.

"In 2013, we had Astro Insulated only, which was 20" x 72", weighed 1 lb., 11 oz. and was insulated with PrimaLoft. In 2015, we have Astro Insulated 20R (20" x 72", 1 lb., 11 oz.) and Astro Insulated 25L (25" x 76", 1 lb., 14 oz.). Both continue to utilize PrimaLoft insulation. The color has changed from Yellow to Dark Riptide (blue)".

The 20R offers 3" of thickness and is reported for use in 15-25 Fahrenheit (as is the 25L), while the 25L costs $20 more and weighs an additional three ounces, but offers five additional inches of width, as well as an extra inch of thickness. Below you will find a side-by-side comparison of the latest models on the far left (20R) and middle (25L) and the older version on the right.

The Nemo Astro Insulated strikes a sweet spot between lightweight backpacking pads and ultra heavy car camping pads. It's warm, comfortable, durable, reasonably lightweight, and packs to a manageable size.

The pad is considerably more comfortable than thin pads like Nemo's Zor and it's slighter wider than the NeoAir XLite. However, its built-in pillow is unnecessary, uncomfortable for tall people, and adds extra weight. Our testers prefer pads that have uniform flat surfaces.

The Astro Insulated falls into the synthetic insulated air core construction category. Its baffles are 2.5 inches high and have a thin layer of open cell polyurethance foam welded to the top inner surface. This foam helps to reduce air circulation, which in turn keeps you warmer. This pad is warmer than all of the self-inflating foam pads we've tested and is plenty capable of all three-season activities.

The Astro Insulated also scores highly for durability. Its 75-denier polyester fabric (top and bottom) ensures the pad doesn't pop upon the slightest encounter with abrasion. This pad is more durable than lighter sleeping pads such as the company's Zor and ultralight NeoAir pads (XLite and XTherm). Another plus: it's nowhere near as noisy as the NeoAir series.

Price. Here, too, the Astro Insulated scores well. The pads retails for a modest $110. Overall, the pad's combination of comfort, durability, and value make it our favorite do-it-all pad where saving weight isn't the top priority.

The Astro Insulated is the only sleeping pad we've tested that has a built-in pillow. (The pillow is an oversized air baffle that sits about two inches above the rest of the pad.) Some of our testers loved this feature while others didn't. It's useful when you want a pillow but don't have any material to make one (when traveling and sleeping in all of your layers), but it can be a nuisance if you want to lay your head directly on the mat without a pillow (you have to move down farther). We had five testers compare the comfort of seven of the newest we pads tested in this class. The consensus regarding the Astro's pillow: those who sleep on their side and back liked it, those who sleep on their stomach didn't. Taller people (>70") will find the pillow to be most inconvenient because their feet will hang farther off the pad. For example, this author is 74" tall. Instead of making a pillow above the pad, on the ground, he has to make one on the pad, which forces his feet to dangle off the pad about three inches more than they normally would. Most people won't find the pillow to be problematic, but it's worth keeping in mind if you're taller.

Though durable and comfortable, the Astro Insulated is no ultralight gem. The pad weighs 24 ounces, which makes it one of the heavier sleeping pads we've tested. How much is 24 ounces? Answer: it's one ounce less than the fully featured Feathered Friends Hummingbird 20 sleeping bag and twice the weight of the Therm-a-Rest NeoAir XLite, the lightest comfortable sleeping pad we've reviewed. This drawback makes the pad best suited to people who want one pad to do everything from car camping to base camping, and multi-day trips in the back country. Its weight isn't ideal for longer trips, but the pad guarantees a comfortable night's sleep and it won't pop easily. Though not weightless, some say a good night's sleep is priceless.

The Astro Insulated most directly competes with the Therm-a-Rest NeoAir Trekker ($120). The Trekker is slightly less comfortable and slightly less warm, but it also packs smaller and weighs four ounces less. We believe the Astro Insulated is a better all-purpose pad for people who car camp or base camp more than they backpack.

Other Versions and Accessories

The Astro Insulated can be paired with the Nemo Pillowtop, a thin foam cover that slips over the pad. Although the Astro Insulated is often sold with the Pillowtop, we recommend getting the pad by itself. For lightweight, three-season use, the Nemo Zor weighs ten ounces less. For car camping, we recommend the Nemo Cosmo Air for its width and durability.

For inflation consider the Nemo Disco Pad Pump, a 2.2 oz. foot pump or the Therm-a-Rest NeoAir Pump Sack (3.8 oz.), which doubles as a camp stool, stuff sack, or backpack liner (it's compatible with the Astro Insulated). We highly recommend one of these for inflating the pad in the winter, when water vapor from your lungs condenses inside the pad.

Looks great and feels comfy. Have not yet slept on mine but want to comment on the recommendation for the Therm-a-Rest NeoAir Pump Sack, which I also bought. At first, I thought that wasn't compatible after all. But yes, there IS a way to get the unmodified vinyl valve over the rather bulky Astro sleeping bag valve, so persist! I managed it with one hand in the bag and the other guiding the Astro valve semi-sideways into the stretchable hole. I also pre-stretched the vinyl hole a bit by pushing two fingers through it, but that probably wasn't an important step. The rest was easy.

Bottom Line: Yes, I would recommend this product to a friend.
