Pros:  Comfortable, warm, versatile
Cons:  SV System slowly leaks, edges collapse under load, noisy, heavier than NeoAir XTherm and XLite
Bottom line:  The All Season used to be one of our favorite pads. The new SV system leaks so we can't recommend it.

Our Verdict

The All Season SV is a warm and comfortable sleeping pad - if it stays inflated. We found problems with the SpeedValve (SV) inflation system (more details below). Stay with the Editors' Choice winning NeoAir XTherm.

Important Product Update — May 2017
Therm-a-Rest EvoLite
Therm-a-Rest has redesigned the classic NeoAir All Season this year, and it is now only available with the SV system. We've outlined all the details of this change below, but the skinny is this: we can no longer recommend this pad and instead highly suggest that you stay away from this pad or any pad with the SV inflation system.

The New NeoAir All Season SV vs. the Old NeoAir All Season


Therm-a-Rest has redesigned the classic NeoAir All Season and it's now only available with the SV system. The All Season used to be one our favorite pads. However, we can no longer recommend this pad because of the SV inflation system. The SV system slowly went flat on us in testing, making the pad virtually useless. We read through many user reviews online and found this is a common issue. Worse, it costs more than the old version and is 7 ounces heavier. We really hope Therm-a-Rest fixes this by re-releasing a non-SV version. Until then, stay away from this pad or any pad with the SV inflation system.

Here's a full description of this year's changes:
  • Price Increase — Along with the addition of the SpeedValve came the disappointing $10 price increase. Now retailing at $170 for the regular-sized pad, this pad wasn't cheap before, but we no longer feel that the price is justified with value.
  • Weight Increase — This pad is 7 ounces heavier than the non-SV version, which we might have been willing to accept if the SpeedValve was revolutionary; on the contrary, we're once again disappointed by this change and hope that Therm-a-Rest re-releases our tried and true NeoAir All Season again soon.
  • SpeedValve — Here's the nitty gritty. Therm-a-Rest wents to improve the inflation system but came up short. The SV system is designed to be more than three times faster than the classic valve on the inflation side with nearly instant deflation. This sounds great, but in our hands on tests we didn't find it dramatically faster to inflate. It then leaked on us. We've read countless reviews of leakage through the SV system, so we ordered a secnd SV pad and tested it again. Lo and behold, we had the same problem. The pad slowly went flat on us, so we feel inclined to warn you against using any pad with the new SV system.

We're long-time lovers of Therm-a-Rest and sincerely hope that the new SV system is scratched and replaced with the old system. If that happens, we'll be sure to let you know. For now, though, we'd stay away from the SpeedValve (SV).

Hands-On Review of the NeoAir All Season


The Therm-a-Rest NeoAir All Season is a top contender that is very comfortable and quite warm - when it stays inflated. It strives to be a good balance between performance and comfort.

Performance Comparison



The chart above displays the overall score received by the NeoAir All Season (highlighted in blue) throughout the testing process. Keep reading below for a breakdown of the scores in each individual metric.

In our comfort category  the rectangular shape of this pad helped it edge out the Editors' Choice winning XTherm with its tapered design.
In our comfort category, the rectangular shape of this pad helped it edge out the Editors' Choice winning XTherm with its tapered design.

Comfort


The All Season is a rectangular winter pad in Therm-a-Rest's NeoAir series. Its shape gives you more space at the head and feet, which many testers find more comfortable than the mummy shapes of other pads like the Therm-a-Rest NeoAir XTherm. The rectangular shape of the All Season was especially appreciated by side sleepers whose feet often roll off of tapered pads. Another advantage of the boxy shape is that it is easier to balance your pillow.

More importantly, our testers loved this pad's relatively flat sleeping surface. Consistently, our testers found that the flatter a surface is, the more comfortable it is. We found the All Season nearly as comfortable as the NeoAir Venture. Both feature a similar design, but the baffles on the All Season are quite noisy and sound like you're sleeping on tin foil. When bundled up tight, our sleeping bags provided quite a bit of noise dampening. But on warmer nights, the sound was intrusive to the sleep of some. For this reason, the All Season drops to an 8/10 for comfort.

As you can see  the baffles on this pad are quite shallow. Our testers consistently found this more comfortable than designs with deep baffles that tend to pull your body into them.

Weight


Tipping the scale at 24 oz, the All Season is considerably heavier than the XTherm and Therm-a-Rest NeoAir XLite. For this reason, the vast majority of our testers reach for those pads on weight-conscious trips.

Warmth


With an R-value of 4.9, the Therm-a-Rest All Season is among the warmest pads we tested. Although not quite as toasty as the XTherm, it's still a good choice for winter use.

The shallow baffles of the All Season make it quite comfortable for back or side sleepers. Further  it is warm enough for winter use.

Packed Size


As you can see in the photo below, this pad packs small, but it's still larger than most other NeoAir pads. However, relative to most of the pads in the review, this one is about average in size.

Packing down to about two liters in size  this mat is quite packable.
Packing down to about two liters in size, this mat is quite packable.

Durability


The All Season uses a durable 75-denier polyester and 70-denier nylon that make it more than sufficiently durable for extended use and abuse. The material is bomber. Our testers have logged more than 365 nights on one of the old All Season pads without any leaks or tears. However, we have found the SV inflation system on the new All Season slowly leaks. Therefor, what used to be one of the most durable pads in our tests, now gets a low score.

Our extensive testing has shown that Therm-a-Rest NeoAir pads are exceptionally durable. Daniel and Donna rode their bikes from Ireland to China with our NeoAir All-Season. Here's Donna in the Iranian desert.

Best Applications


The All Season is a great all-purpose pad for year-round use. It may not be the highest performing piece of equipment due to its heavier weight, but it's comfortable and warm. If you want one comfortable pad that you can use year round, then this pad is a top contender from roadside sleeping to high alpine bivies.

Conclusion


True to its name, the Therm-a-Rest NeoAir All Season provides year-round warmth. The boxy design is more comfortable than the weight saving mummy shape of similar pads. It has a flat surface that is a dream to sleep on but some testers complained that it is too noisy. We just hope that Therm-a-rest will bring back the old non-SV inflation system.
Pictured here  the All Season is used side-by-side with the thicker Big Agnes Insulated Q-Core. We found the All Season to be the more comfortable of the two.

They have also made a new model this year, I would like to know how it fairs. Its the Therm-a-Rest NeoAir All season "SV" with "Speed valve". The sizing is different as they have a wide fit smaller (shorter) size instead of having to purchase a large (longer) pad to receive that extra width; its a 5 inch width increase. Anxious to see what our Gear Gurus have to say on this version of the NeoAir All Season.

I've used this pad in just about every season and weather type and it has never been the reason for me being cold. It's a decent size and weight for the additional comfort of its size. My other pad is an exped winter lite, which is much warmer but not as versatile due to the narrow profile. I use the NeoAir all season for everything unless I'm absolutely pushing the limits of my bag during light and fast climbs in the shoulder seasons or winter.

Yes it crinkles a bit.

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