Cushy and warm enough for any season, and light enough for the stingiest backpackers.

In the world of lightweight backpacking, the less an item weighs, the fewer features it's supposed to have. Not true with the Therm-a-Rest All Season All-Season Sleep Pad. The patent-pending Triangular Core Matrix technology creates over 100 cells and reflective barriers to trap warm air without the bulk of regular insulation, so you can enjoy unprecedented comfort on the trail in any season.

  • Tough, lightweight nylon on the bottom of the pad withstands rough campsites and the reflective polyester fabric on top enhances warmth and comfort by remaining soft and dry as you sleep
  • Lightweight, insulation-free design has an R-Value of 4.9 and features a reflective barrier to send warmth back towards your body and preserve precious body heat during winter camping
  • Patent-pending Triangular Core Matrix uses more than a hundred cells to keep air from shifting around for a more stable sleeping surface compared to other non-insulated sleeping pads
  • Inside its 2.5-inches of cushioning are two layers of cells, which allow the top cells to recirculate your heat and the bottom layer to insulate against the cold Earth
  • NeoAir insulation-free technology lets you pack the pad down to a 9 x 4.5in roll (regular) for easy storage in a pack while weighing a little over a pound
  • Inflation valve can be inflated by mouth or by using the included mini pump
  • Three sizes, medium, regular, and large, fit your size and weight preferences
  • Made in Seattle, WA to keep things domestic
  • Item #CAS0701

Good Night Sleep

  • Familiarity: I've put it through the wringer

This is my first sleeping pad since my original Therm-A-Rest Trail Lite about 2006.

The weight is great on this pad. It is not as light as my recently purchased X-Lite, but it is warmer. It rolls up pretty small and the included air pump is pretty awesome if you do not want to use your own breath. I still have to use about one breath to get it to the firmness that I like it.

All in all this is a stellar pad at a great deal for a do everything, in any type of weather pad!

Pretty Good

  • Familiarity: I've used it several times

This is a good pad and wouldn't have any complaints if I wouldn't have used the Sea to Summit Comfort Light first. This is comfortable and gets the job done but the Sea to Summit is crazy comfortable. This pad is a little noisy as well. To too bad but it is noticeable. I also prefer the valve on the Sea to Summit. This valve works fine but the Sea to Summit allows for faster inflation and deflation.

It may as well be my bed!

  • Familiarity: I've put it through the wringer

I have long since abandoned the roughing it style of sleeping in the backcountry. Gone are the days of thin close cell pads and piles of clothes used as a pillow. Given the weight to benefit ratio of this pad (durability, comfort, ease of set up and warmth), it hardly feels like an indulgence, but more a necessity for sleeping soundly. The mini air pump is a stroke of genius and I delight in using it to help set up my camp. You turn it on, go tend to other set up tasks, come pack and finish inflating the pad with just a few extra breathes. A solid pad, that I would give 6 stars to if I could.

Comfortable, light backpacking pad

  • Familiarity: I've used it several times

I spent 10 nights on this pad in Alaska and found it to be very comfortable and easy to use and pack. Quality seems good and hopefull it proves to be durable. The pump takes a minute to figure out but works very well - takes about 3 minutes to fully inflate. Very happy with pad so far and recommend it for a backpacking pad.

Comfy, but some drawbacks

  • Familiarity: I've used it several times

This is a great mix of comfort and weight for an awesome price! I have spent many nights on this pad and have never once been uncomfortable. I did have some slight issues with deflation, but never to the point where I was just sleeping on the ground. It's a lightweight option that's easy to set up and makes for a great night's sleep. The pump is a nice little feature, but I did find some issues with it because it took a long time to get inflated and I felt that it would have been more efficient to inflate with my mouth instead, but that being said it's a nice feature and does work. All-in-all, this pad is awesome and I would definitely recommend it!

Portable mattress

  • Familiarity: I've used it once or twice and have initial impressions

This is a great sleeping pad if you feel like lighter weight options aren't giving you enough cushioning, especially for the weight and price. Its not bulky or difficult to carry around, and inflates to at least twice the size of more traditional lightweight sleeping pads. That being said, I felt a little too high off the ground in this, and I constantly found myself rolling off of it in the middle of the night, even though the pad is pretty big. I'm very petite, so I'm not sure someone taller than me would feel like they had enough space.

The pump is a nice touch, but we were setting this up in high winds and couldn't figure out how it worked. It's a great idea, just requires calm conditions to figure out. Without the pump, this took quite a few breaths from me and my boyfriend before it was fully inflated. I was just borrowing it for the weekend, so for myself, I'd choose something much slimmer and simpler, but this felt like a well-made pad that would last, and it held air all night. If taking up a little extra space to be high off the ground isn't a big deal to you, I'd go for it.

Comfortable and durable

  • Familiarity: I've used it once or twice and have initial impressions

Other reviews are spot on regarding this product. Lily pad green is the new hip color this season and this can be used for signaling purposes incase something untimely happens. Does make crinkling noises but it didn't really bother me as much as my tent mates gassiness. Tried to use it in a lake as a floatation device and don't recommend it for that usage. Came with a stuff sack and an air pump which were nice add ons. Backcountry got it to me quickly with two day free shipping. Awesome product! #goatworthy

Light, affordable, comfortable

  • Familiarity: I've put it through the wringer

This pad had been on my wishlist for a while before I finally caved in and bought it. This is definitely a good purchase, a quality product at a fair price. It's comfortable and lightweight and a good, solid buy.

I've used it both on summer and winter trips. I don't use a pump.

Great pad for comfort, a bit noisy

  • Familiarity: I've used it several times

I like this pad, it is very comfortable. It inflates with the included pump pretty quickly and a few puffs of breath make it complete and ready for a good night's sleep. That it provides well (mostly). It is a bit noisy when moving around on it. If you are sleeping with others in the tent, you/they might want earplugs. The best description I can give about this is the sound of a cereal bag. If you stuffed a bunch of crumpled cereal bags into this and rolled around, that's about the sound it makes. Not too bad, but noisier than other pads out there. I like the horizontal tubes rather than the vertical tubes in the Big Agnes insulated one. Big Agnes does make one with a cross-hatch pattern that I'd like to try.

Surprise Pump!

  • Familiarity: I've used it once or twice and have initial impressions

I've owned a more traditional Therm-a-Rest Basecamp Pad for probably a decade now and wanted to give something newer a try. I settled and this model based on the reviews. I love that this comes in at nearly half the weight. It was also a pleasant surprise to find a battery pump included. The pad's fabric seems more fragile so my biggest concern will be to see how it holds up over time.


  • Familiarity: I've used it several times

I have the regular size, it came with the little battery pump that is $40. The pad is completely comfortable and you don't feel the warmth being sucked out of you. I have used it so far through the spring and summer, soon enough will be tested around freezing temps (doubt I will have any issues). It is very easy to pack and the pump fits into the top of the stuff sack adding very little weight. I am using the pad with a Marmot Hydrogen sleeping bag.

Yes the pump inflates the mattress, but not fully. I only take maybe 3-4 breaths and it is as firm as you'd want. I simply start the pump while I am doing another activity such as putting on the rainfly to the tent or prepping for a meal. All in all plenty of room for myself, comfortable, and worth the slight weight over the regular neoair.

Comfortable, light and warm

  • Familiarity: I've used it several times

My first night of sleep on this pad was the best I have ever had in the backcountry! I purchased the large because I roll around a lot in my sleep and I never rolled off in the middle of the night. I was a little concerned about the warmth because it got down into the low twenties on the first night. I thought that my 30 degree bag coupled with this pad wasn't going to cut it but I was pleasantly surprised by how well I slept. I used the pad about half inflated and I have never been so comfortable on a backpack-able sleeping pad. I will say that a large pad takes a good set of lungs to tackle airing it up.

Bought for back packing

    I bought this to replace my old thermarest guidlite. I bought the allseason because of the size and how great it is that it fits inside my pack instead of the huge guidlite which is always strapped to the outside of my pack. Its 2 1/2 inches off the floor and it feels amazing. Im 5'9" 190 pounds and i sleep great on it. I dont feel i slipp off as some say but i do here the crinkling sound but its not that loud and i guess i got use to it. I cant say how warm it is during winter but i can say its great in spring and fall. It went from backpacking to my everycamo sleeping pad.

    Does the job

    • Familiarity: I've put it through the wringer

    I have used this mat on several long multiday kayaking trips in Nepal - it packs small and is Nice and light- important points when you are in the Bottom of a canyon and need some rest but have to carry 10days worth of kit in your kayak- the material is strong enough and is still fine even without using the inflation pump-bag.

    Does the large fit in a bivy sack OK? Specifically, the OR alpine bivy? I'd like to get a rectangular pad for comfort in a tent, but I do spend a few nights a year in a bivy, and I'm worried it won't fit, especially down by the feet.

    Hey Galp,

    I would not recommend using a rectangular pad for a bivy sack like the OR alpine bivy. That bivy is tapered at the feet to cut down on weight and to keep you warmer. This pad wouldn't fit.

    The large size of this pad it also 25" wide, while that bivy is meant for pads that are 20" wide, and taper down at the feet. Unfortunately comfort and bivy sacks are not synonymous.

    Is the neo air pump included with the pad?

    I am going on a year long backpacking trip in September and it'll be through Europe, Africa and Asia. Would this be comfortable enough to be slept on for a year as well as durable enough?

    Best Answer


    This pad would be great for travelling through those continents.

    Any time you're looking for longevity from a sleeping pad, I make sure to make sure that I am not putting the pad directly on either rocks or any debris that can puncture the pad.

    With an R-Value of 4.9 this is a great all season pad.

    I second that. I just spent 6 months sleeping on this pad every night while ice climbing and fishing in Northern Patagonia, then later on Aconcagua and Mercedario in the north of Argentina. Just starting to show signs of wear after 100+ nights. Like Jared said, I'm careful about putting it places it could get punctured, and with that small thought its just about as comfy as my bed at home..

    Would using this pad with a Big Agnes Zirkel bag work? The bag is mummy shaped, but this pad seems only avaiable retangular-shaped. I'm wondering if the pad would stretch the bag at the foot.


    The Big Agnes Zirkel can take up to a 20 inch wide rectangular pad.

    If you are looking at either the short or medium length for this pad, those will both work since they are 20 inches wide.

    Unforunately the long will not fit as it is a 25 inch wide pad.

    Hello! I am interested in this NeoAir All-Season Sleep Pad, so could you please tell me that do I have to purchase a inflator pump for it? or just pump it as manual ? please kindly advise me, thank you!

    I've been trying to decide between this mat and theXtherm. Does anyone have any comments to help me decide.

    There is a small R-value difference (4,9 compared to 5,7) would i find any difference?

    To me it seems like the all season is a little bit more durable, does anybody know if that matters at all, i mean would there ever be a time where one would leak because of that but not the other?

    And there is a little weight difference, 140gr. Doesn't seem that much seeing that there is more room on the all season. I had the thermolite plus and I sometimes woken up when my feet slip outside onto the snow.

    if anybody could help that would be great!

    Best Answer

    I have the X-therm. I haven't beaten it to death, but I don't have any real worries about its durability. It's a clearly well-made piece.

    The large X-Therm is quite large, and I have no issue staying on it. I will say that because it's tapered, it fits a little better in some tents, and the rounded shape at the top makes it easy for me to have stashes of things around my head but clearly off the mat.

    So... X-Therm is a little warmer (20%), a little lighter, and probably fits a little better inside a tent. It's also a little more expensive. My guess is that it packs way smaller too (mine rolls up into a nalgene sized roll--even when I'm packing quickly in the woods).

    Very happy with the X-Therm.

    So I've used this pad in just about all conditions so far. From the back of my subaru to mount Rainier with a little desert action too. This pad really is all season. I use the neoair xlite for going light in the summers too. I've heard that the Xtherm get very warm in warmer climates. I think in terms of durability, with the All season is a little thicker "feeling". What it can come down to is the shape! I have both pads in REGULAR, but with the mummy shape and idea of winter camping, going with the large would be better off.

    So if you're looking for a do it all pad: All season. Winter specific, Xtherm.

    Both are ultralight, ultra compact. I did end up buying a pumpsack to reduce condensation.

    Currently thermarest is including the mini pump with this pad. Any chance backcountry is doing the same?

    The pump bag is really only worth it for emergencies.... like if you can no longer breathe and want to prepare a comfy final resting place.

    Honestly people say to use the pump bag to avoid moisture getting in the mattress (from your breath). It's A LOT slower to use the pump/bag.

    Understand all that, but if you buy from Therm-a-rest they currently include the battery powered mini pump.

    Would prefer to buy from BC, but will buy direct if I get this freebie.

    Would this be good for climbing Rainier?

    Most definitely, my lady used this exact pad while we summited both Shasta and Rainier. I used the updated neoxtherm gray pad. I have used the pad myself many times and can confirm its packability and warmth. Paired with a good bag, you'll never get cold.

    I notice there is a lot of emphasis on the warmth of this sleeping pad. I am looking for something that is comfortable for a side-sleeper, and warm on those chilly nights, but I am curious how the body heat reflectors deal with warm summer temperatures. Do people find themselves overheating in the summer? I would appreciate any insight. Thanks!

    The R value on this pad is 4.9. The most popular therma pad for backpacking is the the Prolite plus and has an R value of 3.8. I the summer you would not really notice the difference between these pads but in the winter you would. You should not real have any problem with over heating in the summer unless the night time temps are really warm (80 plus degrees). You might feel warm on this pad say if you are taking an afternoon nap in a summer. If over heating is a real concern then you should consider the Neo Air Xlite. it has an R value of 3.2 and will work all summer long plus on most of the shoulder seasons. If you are using it in the winter you will definitely want the All Season version.

    I currently own and use the standard...

    I currently own and use the standard (yellow) Neo air and have noticed on some occasions I start with it fully inflated and then during the course of the night it will deflate some, maybe due to change in outside air temp.?? Anybody have any ideas on what's up with this?

    Most pads do deflate a little overnight. If you're blowing it up manually, you're essentially blowing hot air into it, which might cool as the night goes on. My other guess is micro leaks or a sketchy valve, but if it isn't too dire i wouldn't worry. You can always test if there are any leaks by filling it up, putting it in the bathtub and looking for air bubbles.

    The culprit is hot air in and then cooling off over the course of the night. It is far more noticeable in air-only mattresses when compared to foam-based mattresses. No need to worry about leaks as this is very common. I simply get up, put a few more puffs in the pad and go back to sleep. Once I understood the reasons why and prepared my mind for it, it stopped becoming an issue. I simply prepared myself for blowing a few more breaths in it at night. It was amazing how much better I slept when I didn't worry if my $160 mattress didn't have a small leak!

    I can also guarantee that there aren't any micro leaks or sketchy valves. If there were, the pad would be completely flat in about an hour's time. If it's simply loosing some air pressure, but not an alarming amount, then there shouldn't be any leaks.

    Should I trust this pad for sleeping on...

    Should I trust this pad for sleeping on wooden planks in AT shelters for months on end? I need comfort, insulation and weight-saving, but packed in a durable shell, is this it?

    I have a neo-air and love it for comfort. If you're going to be out for months on end, you're taking a risk by only bringing this pad - there's always a chance the inflatables will puncture. That said, I'd probably still use it (the good night's sleep is worth it for my temperamental back) and just be careful to put some sort of barrier between it and any wood planks that might have splinters. I have two 45# pups who do walk over these in the tent - their nails have never punctured one yet…so that's all I’m basing my comment on. You're def going to find people falling on both sides of this issue. Perhaps just consider bringing a tiny repair kit if you'll have time and the ability to find and fix punctures along the way.

    I agree, one should never go out with an inflatable pad without a repair kit. That is simply asking for trouble. however, no need to bring the entire kit, but instead, just take the items that you need in the repair kit and it will hardly weigh a thing.
    That said, if you are going to be out for months on end (or really even for a single night) I would imagine that you have a shelter of some sort, and maybe a ground sheet to go with it? The Gossamer Gear Polycro ground sheets can be cut down to weigh less than an oz and still be a little bigger than the size of your pad. Just simply use your ground sheet inside the shelter under the pad.
    Also, it is always good practice to treat any air pad as just that. Before laying it down, check the area for sharp objects. I understand that sometimes accidents happen, but a quick rub over with the hand should tell you something about the spot.
    Good luck!

    I was wondering what the different is...

    I was wondering what the different is between the All season and the Neo Air and the Neo air trekkers? Is it only the weight and the isolation?

    the all season and the trekker are made of a thicker (and arguably more durable) material, making them weigh more. my understanding (i do not own the all season or the trekker neoairs) is that there is no insulation. it is reflective surface that keeps the radiant heat moving around inside the pad itself. the regular neoair has fewer of these surfaces, meaning less radiant heat is retained.

    The All Season is designed for cold weather trips that require a sleeping pad with a higher R value (the higher the R value, the more insulation the pad will provide) but is still lightweight enough to be used for most three season trips. The NeoAir is the lightest-weight pad of the three, designed for ultralight trips during the three seasons. The Trekker has even less of an R value than the NeoAir and is a lot heavier at about 19 ounces. It seems that the Trekker is just a cheaper version of the original NeoAir.

    Comparison (all 20" by 72")
    All Season-19 ounces, 4.9 R value, $169
    NeoAir-14 ounces, 2.5 R value, $169
    Trekker-19 ounces, 2.0 R value, $139

    Best Answer

    The original neoair (yellow) was created to be extremely lightweight and warm with the built-in reflective material. There was a lot of complaints about holes/leaks because the material wasn't very durable.

    Soon after the trekker was released. It has a 75-denier textured polyester fabric on top and a 100-denier polyester on the bottom to help with the durability issues. The trekker does not have the same reflective material within, hence the 2 R-value compared to the originals 2.5 R-value. Because of the heavier duty fabric, the trekker weighs 6 ounces more for the large size (26oz instead of 19oz).

    The all-season has the same 75-denier textured polyester fabric as the trekker on top but only a 70-denier nylon on the bottom. So it's thickness is somewhere between the neoair and the trekker in terms of bottom thickness.

    Hey there, New to the "air" sleeping pad...

    Hey there,
    New to the "air" sleeping pad technology. In comparing the NeoAir series - do they all have the same exterior material? I guess what I'm asking is do they all have abotu the same "slip" factor - frictions between the sleeping pad and bag? I hear hte Neoair is better than others when it comes to this detail (Exped/BigAgnes), but I don't know if within the Camprest inflatables if one is better than another..

    Best Answer

    They do not. The standard Neoair (the yellow one) has a very thin material, whereas the Neoair All-Season uses the same material as the Trekker --- a thicker and more durable material. Having owned the Neoair (returned it), the Neoair All-Season, and a Prolite (my first air mattress), I'd say that both the Neoair and Neoair All-Season are less "slippy." I also own a cushy Exped and that might be the least slippy, but it's heavy and bulky and I never use it on climbs. BTW, the reason I got rid of my Neoair and got the Neoair All-Season is because the thin material on my Neoair somehow managed to puncture on who knows what -- it's just not that durable.

    This mat is for sure tougher and more...

    This mat is for sure tougher and more insulated in comparison to the standard yellow NeoAir, but it is also more comfortable?

    Since there seems to be a CD rep lurking...

    Since there seems to be a CD rep lurking around here (Jason Livingston)...

    Does the All-Season make the same "potato chip bag" rustling sound as the standard Neo Air?

    And, off your quote, "but the benefit is that it will take you into January where as the standard NeoAir will most likely need an additional barrier (Ridgerest or Z-Lite) to allow it's use in winter."

    Are you saying, that the All Season is good to go on top of snow? I would assume not, and that an additional barrier is needed for the All-Season even when snow camping. I'll be happy to be wrong.

    Thanks for any answers you can provide.

    Best Answer

    Until Jason gets around to it- Don't know about if this one crackles like the NeoAir, but here's the math on R-values.
    NeoAir All Season- R= 4.9
    NeoAir- R= 2.5
    Zlite- R= 2.2
    total-R= 4.7

    RidgeRest-R= 2.8

    So, slightly more than the All Season's 4.9 with the NeoAir combined with the RidgeRest, and slightly less with the Zlite. I call that one roughly a draw, but with only 1 pad and less bulk. Hope that helps.
