Therm-a-Rest NeoAir All Season SV Review
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.
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.

Our Analysis and Hands-on Test Results
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:
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.
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.
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.
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.
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.
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.
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.
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.
