I've had my Neoair out for a couple of trips now. Here are some observations:
Expensive, but I used my REI dividend, so I told myself it was OK to splurge.
It's very comfortable - feels much like the other airpads I've used - cushy.
Weighs in right at spec - 13 ounces for the medium.
You can feel the warmth of the pad when you lie down on it - nice.
Some people complain that it has a crinkly noise - I didn't really notice. I like my mattress pretty firm, if you have it only partially inflated it makes a bit more of that "crinkly" noise.
I inflate it when I set up camp, and then top it off before I settle in for the night.
I brought along a piece of blue foam to supplement, in case it got cold. Would start the night out with just the Neoair, to see how it felt on its own. The trips were to Yosemite, the first trip in April and the second in May. Both times the temperature dropped below freezing.
As the temperature dropped into the thirties I would feel cold. Added the blue foam on top of the mattress and was fine after that. The coldest night was in the twenties, woke up with frost covering the tent and the world around me, but with the blue foam over the Neo I was warm and slept well.
The blue foam is from REI and cut down to a 6 ounce pad. I also bring it along as insurance in case the Neoair goes flat.
My old pad is an Pacific Outdoor Insulmat and the Neoair is very close in terms of comfort and warmth. But the Neoair is almost 10 ounces lighter!
My very hazy understanding of physics says that the warm air that I blew it up with looses volume as it cools. Happened with my old airpad to. The way I solve it is to blow it up when I set up camp, then top it off with a breath or two before retiring.
this will shave a LOT of weight off my pack. If it stays up. I was looking at the exped, but i'm kinda trusting the warranty and my care of it to not puncture. Although, i'd rather it was not Limon. Looks to be almost as thick at the exped, so i'm not so concerned about that. Thicker than what i use now. i always lay out the thermarest and blow right before i go to bed, a second time. just to keep it where i like it.
I got to use my new pad that Cascade Designs replaced for my leaky one this last weekend. Nice to have something so compact and light. The color is ok, it is covered up by my bag anyway. Must say though, that I slept better on the Lost Coast trip than I did last weekend using this pad. My shoulders must be sore from cutting/splitting firewood and the swimming with the young ladies on the trip too.
I just used my neoair on a backpacking trip to Yellowstone and the Teton Crest trail. It worked perfect and I slept like a baby. I have a question, do you store the neoair loose and with the valve open like the old thermarests, or in the stuff sack?
To avoid folding in the same place, at least for now, I deflate mine, a slow job, roll it up, then fold in thirds and use a small Granite Gear stuff sack which is way cheaper than the Cascade Designs sack to store it and protect it. I just need to pick up some goop to seal leaks if they ever develop.
