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

Here's what others have to say...

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?

Responded on


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.

Shoot me an email if you have any more questions!

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.

Responded on


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 Responded on

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.

Responded on

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 Responded on

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.

Responded on

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.

Responded on

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.

Responded on

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 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!

included air pump ?

sleeping pad okay,,, darn it,, still looking for the "included" air pump,,, funny thing, found only a funny bag with a short rubber tube,, maybe a funnel,,,,, lol,, anyway ,, ordered the NeoAir Mini pump ,,,,,,

Responded on

That is the pump. Its not a battery run pump or T pump. You have to fill the bag and press down on it so it pushes air into the pad. Takes forever, seems less efficient but it prevents from spit going inside. And if you order the mini pump it will only fill up so much before you are going to have to finish it yourself by the pump sack or by mouth just because its such a small battery powered device.

Warm and cozy

  • Familiarity: I've put it through the wringer

This pad is great! My wife has it and I steal it all the time, it's way lighter and more comfortable than my pad and super warm! Sometimes we just bring a blanket camping and I am usually cold since there is no insulation between me and the pad and she is warm which never happens. So the pad makes a huge difference.

Overall Great Sleeping Pad

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

Recently used this sleeping pad on a 4 night trip to Isle Royale, MI, and it worked great. It can be a bit noisy if you move much in your sleep, but it kept me warm and very comfortable.

Excellent replacement for 32yr old 3/4 T

  • Familiarity: I've used it several times

I first became enamored with Thermarest in the Wind Rivers in 79.My ensolite was flattened. When seams were giving out after 32 yrs, I upgraded . Both my wife, son and I now enjoy the cushy sleeping that I was exposed to in 79. Packs so small and tight is a Big Plus.

Ther-a-Rest Neo Air Trekker Sleeping Pad

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

I had called and talked with one of the Backcountry gear experts. I explained that I was an insomniac and tried a lot of different pads to no avail. I am a side sleeper, my hip or shoulder always bottom out on the ground through the pad, this causes me to wake up sore and I can't go back to sleep. The gear guru assured me I would not have this problem with this pad. This past week I had a chance to try it out. For me I found it took 17 breaths to blow it up each time consistantly that I tried. I am 5'10" 185lbs, muscular build being a trainer. While another 6" in width would be perfect I was very comfortable sleeping on this pad. I did not bottom out my hip/shoulder as with previous pads. I actually slept through the night which is rare for me. I was hesitant at first but he reassured me I would be happy so I took him at his word, at present I can not argue with him as it worked as he described (something I rarely find these days). It packs down small, taking up little space Granted this was my first outing with it and time may tell a different story, however I am grading it based on the fact that it solves the concerns I had when I called for advice. My hip/shoulder does not bottom out and I don't see that changing in the future short of a leak. I camp alone and therefore have no complaints from a noisey standpoint although did not find this to be a problem myself. Jeff
