This has changed backcountry sleeping forever. I have serious hip issues- too much pounding up and down mountains with guide packs, so I have a hard time sleeping on thin pads. I've used this now for four months and have had no holes and no other issues other than the ones that appear in my sweet dreams. I can't say anything bad about these pads. They even come with some repair glue.

just so everybody knows, get backcountry to price match this pad because though they usually have good prices, every other website sells this for around 25 dollars less all the time.

For the climbs that I've been on, we've always been required to bring a self-inflating pad along with a foam pad to adequately insulate from the cold when sleeping on a glacier. Comparing the downmat 9 to my Z-rest/Prolite 4 combination, I'm actually saving 1/4 pound going with the downmat. Plus, the downmat 9 is easily more compact than the Z-rest/Prolite 4 combination. Plus, the downmat should provide better insulation than the old combination and thus allow a lighterweight sleeping bag to be used. The only real downsides to me: 1) I wish it was a little wider (I sleep on my stomach most of the time), and 2) the inflation method is not the fastest. But to be fair to the downmat, it is as wide as my Prolite 4 pad and after getting light-headed trying to inflate my prolite 4 at altitude, maybe having the sack double as the pump isn't such a bad idea. In summary, it would be pretty hard to justify the downmat for the ultralight fanatics out there. But for sleeping on snow for extended periods of time, the downmat appears to me to be a superior solution than the Z-rest/Prolite 4 combo that I was using before.

I like this mat, but hate the inflation method.

I went to Lowes today and found a part that is used for a dishwasher drain to reduce the size. The large end fits on the mat valve and I am able to jam the pump into the other end using the hose that came with the pump. Now I can pump this up to give it a try. My pump is a very small, light and looks like this:

Some of your customers will not want the extra bulk with the pump. The bag system would work if the bag would stay on the valve, but there is nothing to keep it on while you "re-charge" the bag. Also, it is almost impossible to keep the bag on the valve while pushing the air into the mat. I think that this is a very lame inflation system. I have since read reviews where the reviewer admits to forgetting the "pump" and just blowing up the mat with his mouth. This introduces moisture which causes the down to break down much faster. They need to fix this system if they want recommendations.

I'm a back-sleeper who has never been comfortable sleeping on flat surfaces. I need a significant dip for my glutes (butt) or I wake up after a couple of hours with a stiff and sore lower back. The first inflatable pad I ever used that was thick enough to provide the countour I needed was the Big Agnes Insulated Air Core. I would deflate it just enough so my butt didn't bottom out, creating the dip in the mattress like my bed at home.

However, I soon discovered that the Big Agnes did not live up to the "Insulated" part of the product title. In consecutive nights in the low 30's using the BA vs a heavy old well-insulated pad, I woke up chilled on the BA and had to put on some extra clothes. The insulating value of a pad and a sleeping bag work together as a system for keeping warm.

The Exped Downmat 9 does everything the BA does in terms of my back-sleeping needs, plus it insulates enough so that I don't have to also carry a foam pad in cold weather. It inflates very easily with the integrated hand pump: just press down repeatedly with the palm of your hand covering the opened valve.

I have only used the Downmat 9 on one trip so far so I can't attest to its durability, but it seems very well constructed and comes with a lightweight repair kit for use in the field. I would recommend this product for cold-weather use and for those who need a thick pad for a comfortable night's sleep.

I owned the 7 pump version with the pump built into the mattress for a short time before returning it for exchange of the older model (stuff sack pump). It looked great the first time I used it at home but after storage in the sack in combination with cooler temperatures the pump took a real long time to fill the mattress and because this is filled with down, you can't blow it up with your mouth or the pads insulation will be compromised. Other than my pump concerns, this pad works well.

This mat is comfortable and warm. The pump system is really fiddly, but works. I had a synmat (also exped) previously, which is also good. On balance once I'd worked out the pump system, I prefer the downmat.

You might as well take a lighter sleeping bag. I carried this bad boy up to high camp on the Polish Glacier route on Aconcagua. Two nights at -30 F and I never even zipped my sleeping bag.

I'm a side sleeper and had my shoulder re-assembled last year. This is the first pad that I've been able to comfortably sleep on my side with. No cramps, no kinks, no phantom limbs.

I have the regular 7 and am 6' 190 lbs. It fits me fine. I use it for car camping and it's light enough to use backpacking. I can't recommend it enough.

Absolutely love this pad. Used it for a week long trip in the Boundary Waters and never had to repump it. Mine is the old version w/ the stuff sack pump and it worked flawlessly. I slept like a baby each night. I'm a side sleeper and my hip never touched the ground. I can say I have nothing bad to say about this pad at all. It is pricy, but I got mine cheap ($95) because it was a model closeout. "If you have the means, I highly recommend picking one up."

Wish my bed at home were this warm and comfortable. Sleep on my side and don't bottom out. Hands down the best pad I've ever slept on. Only takes about 5 minutes to inflate. Read where other folks had difficulty blowing up.... not sure why. I found it pretty straight forward.

All together I've spent 3 months sleeping on this pad. Better sleep pad than any other product out there. I like it inflated to the point where if I sit up a bit my butt touchs the floor. This inflation level feels supportive and soft and doesn't feel like I'm floating on water.

Used this in -15 - -20 Celsius this winter and slept great ... it was my buddies as he let me test it out. He was not so comfortable on my pad ha ha.

I bought this pad mainly for the shoulder width. I had a slightly smaller exped mat that was very nice but my shoulders hung off. So I was loooking for a exped pad that was a little bigger I found one and the noticed for a few dollars more I could have a down one this is where I made a mistake it is very hot!!! If you plan on camping in a blizzard than it will be nice.I had it on the top of Mt. Shasta and it was still hot!!So when you look to buy this they mean business with the 4 season.

Earlier product reviews of this had me expecting to use the stuff sack as the pump, when mine arrived it was obvious that the sack wasn't going to work that way. when I unrolled the mat I found a section with an air plug and two hand prints - pretty obvious, open the plug, put your hands here and push. I have what they call the 7 pump - maybe with the old bag pump but it takes quite a few more with the built in pump, but it's very easy.

Took to Mt Langley, in Feb 2009, slept on the snow at about 10,300 feet. The temp dropped to around zero degrees F at night. This was the warmest most comfortable sleeping pad I have ever slept on. It is a bit hard to inflate, practice several times at home before you go. The 900 model I got is a little heavy. I think the 700 would work just fine.

and toasty on ice or snow and everything else. By far the warmest pad ever used. Easily the most compact pad ever used, packs pretty small-slightly smaller than 1/2 the size of a standard loaf of bread and is full length pad-stored in my pack now instead of exterior. Integrated pump is nice-take about 40 hand strokes to pump up taut. Easily adjusted to any comfort pressure level. Deflates in seconds and deflation valve mouth actually keeps up when rolling the pad up. Debris falls off pad easily. Easily packs back into included storage bag. Storage bag has nice retainer clip that doesn't allow drawstring to loosen up at all, no extra retaining knot needed. Inordinatly strong-friends daughter along with her little friend and their #10 rat dog actually used it as a snow sled while I was away! I was surprised there was no damage, no streaks or tears as the material is really tough. There is an "UP" and "DOWN" and does make a difference, read the instructions.

We have two of the Downmat 9 Dlx. These are bar-none, the most comfortable mat I have encountered. I weigh 190 pounds and can sleep on my side without touching the ground! (never feel a root, rock, twing etc again!!) You will hear some complaints about the pump, but the reality is that a song or two on the ipod and you are in business. There have been times when I absolutely need to have my tent set up in a hurry, but I have not yet encountered a time that I coundn't trade 5 minutes of lazy work inside the tent for an outstanding nights rest.

These mats have seen nights of -15 F on the north shore of lake superior to hot and humid in the virgin islands. Whatever your pleasure of location, these mats are very capable. We haven't had a puncture or failure of any type so far.

Please keep in mind that they are a bit heavier than your run of the mill Thermarest, but I simply make choices in other areas to make up some of the difference. My wife and I use the Exped coupler kit and it too works well.

One note of caution, the 9 DLX seems bit wide. If you are going to use two of these in a two person tent, you may well be running up the walls. So, be sure to take a measure before you purchase.

I agree with jat120 - if you are a lite-freak, this is not the mat for you, but if you want great comfort in the summer and an easy packing system for the cold, these are fantastic! You will love it or leave it based on your philosophy on weight and set up.
