Exped SynMat 7

I bought this pad last year because I found it on clearance for $39, and I must say that it was definitely worth it! However, just a few short weeks later I bought myself a NeoAir, so I personally haven't gotten a whole lot of use out of it.
Comfort will vary from person to person. Saying that, for me I found that I much preferred the horizontal baffles (such as on the NeoAir) as opposed to the vertical baffles such as the ones on this pad. Don't get me wrong, it is not terribly uncomfortable, just not as comfortable.
The integrated pump is nice, and considering it has a bonded synthetic insulation, it is actually a must. No sense in blowing the pad up full of the hot moist air straight from my lungs, the moisture would eventually break the insulation down. When rolling the pad up though, it does cause a little extra bulk. But if I take my time and remove all of the air from the pad, I can still roll it down pretty durn small.
The material is durable. I let one of my buddies use it on a trip and when we made camp there was no good place to set up my tarp. So, we just found as flat a spot as possible and cowboy camped. Of course the flattest spot had a bunch of huge rocks which slightly jutted up out of the ground. He didn't have a ground sheet so he simply piled a bunch of leaves over the rocks and laid the pad right down on top of that. All night long I cringed each time he shuffled around trying to get comfy, but come morning time, it was still inflated. So, definitely a nice durable pad.
My biggest problem with it is the weight. I can make a NeoAir and a 1/8" ccf pad work for me down to temps the same as the Exped, but at half the weight. I understand that this is not a problem with the pad, but more of a personal preference. At the price I paid though, I have no regrets and would do it again though. And I can keep it as a loaner!
My only complaint is that there is a leak in the bottom of the pump chamber (not the end with the inner valve). I can hear the air leaking back into the pump chamber whenever the pad is fully inflated. And again, it is not through the inner valve. I can put pressure on the bottom of the chamber and it will stop. The problem with this is that if the outer valve cover is not closed the air will leak out.
I sent the pad in to be checked. And I must admit that Expeds customer service was top notch. They kept me informed throughout the entire process. And it only took about 2 1/2 weeks from the time I sent it out my door until it came back to my door. However, they did not feel that it needed to be fixed and sent it back to me. I am fine with that since I don't really use it. But if it ever does worsen, I will not hesitate to send it back again.
I guess I would recommend this pad though, but there are other options now that are lighter weight with the same R-Value. I think a lot depends on comfort, and which type of baffles are more comfortable for you.
Also, if you like these, check out Kookabay.com. Bender makes pads similar to these at a lighter weight and you can actually pick what width, length, shape, thickness, cut, insulation type and R-Value. Of course being a cottage shop, be prepared to have a few weeks wait...

I'm really not kidding: this is the most comfortable pad I have ever slept on. I own the Long/Wide version and wow this thing is huge. I would actually recommend you getting the M size so it can fit into a bivy sack with less hassle and because this thing is already quite heavy. Yes, this thing is heavy. For my purposes of alpine mountaineering, I value my sleeping pad and pillow (yes, I bring a pillow) more than any technical shell I can buy. If I don't sleep well, I will be so sluggish the next day that no Arc'Teryx shell or La Sportiva boots can save me.
For those reasons, I love this pad. The SynMat 9 is just overkill for most purposes but the SynMat 7 M is a great choice. If you want something lighter and just as warm, take a look at the Therm-a-Rest All Season NeoAir (R-4.9) but it won't be as comfortable. Still, I would recommend this Exped pad.
Value your sleep. Get this pad!

This pad is a must for 4 season camping. I bought the Synmat 9 and really enjoyed the extra length and width since I am 6'4" 190 lbs, and I couldn't fit comfortably on the synmat 7 I bought my wife. The pad is SUPER WARM! First night on our Kilimanjaro trip I sweated really bad since I was fully zipped in my 15 degree bag and it was only 30F outside. After that I slept straight on the pad with my bag just draped over me wearhing shorts and a long sleeve T and was warm even at high camp (15,000 ft). It is a little heavy to carry on a really long trip in the summer if it is warm out, but it is definately my new car camping pad.
It took me about 3 minutes of straight pumping to get the 9 pumped up, and it takes about 1 minute to roll it up. Didn't lose inflation at night one time.

Hard for me to give 5 stars for much these days, but it's easy to lay them out for the SynMat. Been an Exped fan since I found the DownMat for winter camping. I sleep like a log on these things. I've discovered that the Deluxe DownMat is actually overkill in weight and warmth for almost all but the coldest conditions. The SynMat let's you save weight and bulk when trying to go light. I don't miss the weight and bulk of the hand pump at all. I wish my DownMat didn't have it built in. I'm still a little wary of getting a puncture, but I carry a patch kit and haven't had any problems so far.
