Therm-a-Rest NeoAir Trekker Pad

In summary, this is a durable, comfortable, compact (when folded of course), and the most affordable pad in the neoair series, which for me, makes it the perfect 3 season pad. You can certainly shave couple of ounces by going to xlite or xtherm. But for the criteria that I use, the trekker is the better choice for the following reasons:
1. I find the rectagular shape of the trekker to be personally better than the xlite and xtherm (just find the shape to be more comfortable).
2. I found the occasional "crinkly" sounds to be minimal compared to the xlite and xtherm as well (xlite being the worst - relatively speaking).
3. And of course this one is the least expensive.
I do think that the all season is the best overall buy however (if you must have a single pad for all four seasons), because it does have a higher R value, not much more expensive than the trekker, has similar rectangular shape, and comparable in weight - but I don't in any way regret getting the trekker. (well, my gf got it for me for b-day....so I'll use it regardless cause I appreciate it).
Furthermore, if you're weight sensitive and/or require higher R-value, you'll have to go up to the xTherm....or XLite obviously.

I got my neoair second-hand and spent about 70 nights sleeping on it over the summer. It's still kicking butt.
You need to be mindful of it (I use a plastic ground-sheet and a thin foam pad under mine), same with any light-weight inflatable sleeping pad, but it's impressively durable considering the size an weight. The only issue I've had came up after a night of sleeping in a campsite full of thorns. The pad got a small puncture, which I was able to find and easily fix with the patch-kit provided, and it continues to work great now.
Blowing it up every night is bit of an ordeal and if you use it at a base-camp you'll find that, over time, it slowly deflates and requires a couple extra breaths every day or so. To me, it's all worth it for the comfort, though.
Ultimately, I would recommend it to anyone who has trouble falling asleep, anyone with back pain, and anyone who spends more than 5 days a year sleeping on the ground.

I got the "large torso" model which is 25 x 47 inches. It weighs exactly a pound according to my cheap plastic kitchen scale. I used this on a week-long backpacking trip and it worked quite well. The pad is nice and thick, so I always had a nicew cushion for my hips, shoulders, and head. My feet extended off the end of the pad but I put some clothes or an empty pack under them and that worked fine. This pad seems to be more sturdy than some of the lighter models; the fabric feels a little bit thicker and tougher.

Final a sleeping pad that really gets you off the ground. You wont miss an hour of sleep with this pad. Sure it takes a little longer to blow up but it is well worth the time. The noise is minimal, especially from within your sleeping bag. I also found that I can sleep on my side with this pad and still not hit the ground. I'm 5'10" and 145lbs.
I would recommend the regular to anyone who is around my size and needs that added cushion between them and nature.

I've used this everywhere from the United States' Southeast to the banks of the Arctic Ocean (summertime). It gets small enough to fit in my nalgene if I wanted it too yet it is large and comfy enough that it's practically a portable air mattress. Yea I might be a little dizzy taking the last few breaths blowing it up, but I've never fallen asleep on uncomfortable terrain quicker. It breaks down fast and easy and isn't a hassle to get into the provided stuff sack. Great Purchase.

I am 6'3" and the large fits me well. I am very happy with this pad. It is cheaper than the four season version and is only marginally larger and heavier. I felt it was a good decision to save the money and get the trekker vs. the other pads available from thermarest. Mine has never leaked air through the night and typically stays inflated for two straight nights. It is very tough and durable, I would recommend this to anyone looking for a good nights sleep!

Took this out for a week on the AT and slept like a baby. Even on a rocky surface, the pad kept me comfortable. It is 20 breaths to blow it up but not an issue for me. I ordered a regular and it just fits inside my tent. Im 5'10, 185lbs and a side sleeper and it kept me high and warm.If you're looking for a lightweight, compact, very comfortable, warm sleeping pad, look no further!

Took this pad out camping and it worked pretty well. I got a good night sleep on it, and the size worked for me--I'm a medium-sized lady--but it may be on the narrow side for anyone much bigger than I am, particularly the guys. My only complaint would be that it's pretty loud if you toss and turn at all, but once you're asleep, it's all good!

So far, so good! I have only used it about 10 times, but so far it holds air all night.
It packs nice and small, and it's nice and light. It takes a little longer to blow up than some other pads I've used, but I take that trade off for the comfortable sleep any day!
