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 pump valve and sack
  • Pump valve can be fixed to any plastic bag or compression sack for inflating without having to catch your breath in high elevations
  • Three sizes, medium, regular, and large, fit your size and weight preferences
  • Made in Seattle, WA to keep things domestic

warm and light

  • Familiarity: I've used it several times

I have no complaints. I've used it all spring and summer with only great experiences. Packs light and compact.

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?

Yes, the pump is included with this pad.

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.

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.

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.

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!

Best Answer

The stuff sack that comes with the pad has a valve that turns it into a pump sack to inflate the pad. The small ecectronic pump is nice for car camping though.

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!

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.

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.

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

Best Answer

What we call the "pump" on our site is actually a valve you can connect to a bag. You can then use the bag to fill up the pad so you do not have to breathe into it, slightly easier on the lungs but, I think it takes longer.

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.

The Regular size pad that I just received came with the battery powered pump

Solid, but not the best for extreme cold

  • Familiarity: I've put it through the wringer

I've used this pad extensively on winter camping trips and, for the most part, it's pretty solid. It packs easily, is light, and the stuff sack is actually properly sized (unlike those sacks that seem impossible to get the pad back into. That said, on really cold nights it doesn't have quite enough insulation for snow camping. I'd recommend bringing a close-celled pad (great for around camp anyway) in addition to this, providing a bit extra insulation.

I have been using the thermarest prolite...

I have been using the thermarest prolite 4 for my hammock setup for the past 5 years now. looking to upgrade to something smaller/lighter. anyone have experience with this pad in a hammock?

  • Familiarity: I've used it several times

I work in conservation in hawaii and my crew ordered a bunch of these for our camping trips. While some of the members liked them because they raise so far off the ground, others were disappointed with how narrow they are. I constantly found myself rolling off the pad. They do stay full throughout the night which is a plus, i just wish they were wider. It's almost more like a raft than a sleeping pad. Overall, I don't think I would buy this product again.

  • Familiarity: I've used it several times

So far every time i've used it, it's been super warm and comfy. it's really compact and light which makes it that much nicer. Don't really get your hopes up about the pump though I don't really find it useful so the only down side is filling it up because with all the chambers that it was inside it might take a while but you'll appreciate the few extra blows when you're nice and warm in the middle of the night! also the material feels super tough and so far ive had no problems with it!

Light And Compact

This pad packs remarkably small and is light for its size and thickness. While it could use some work, I appreciate the sack/pump concept to avoid injecting my breath's moisture into the pad. I'm 5' 10" and went with the regular size. Overall very satisfied.

All season

  • Familiarity: I've put it through the wringer

I've had this sleeping pad for a couple seasons and it works great for keeping you off the ground. I'm 5'6" and its a bit narrow so I suggest getting a Long if you want the extra room. Otherwise Regular is perfect! Its meant for backpacking so they make them smaller than you may think. It comes with a bag to help pressure into the pad but I have never been able to make that work efficiently so I just blow right into the mouth piece and that works great. I've taken this on the river and camping. Still a great pack if you plan to be out for a couple of days!
