Positive Reviews:

I really wanted to love this sleeping pad. It's unbelievably comfortable, warm, and lightweight. And it seemed pretty durable too, but despite being very careful near sharp rocks and vegetation, I've had 2 of these pads develop leaks in the past 3 years. The first one went while camping in Acadia Nat'l Park in Maine, the second in the middle of 2 months in Alaska! Luckily I usually bring a foam pad along too (to help prevent sharp rocks from digging into the pad, ironically). I was unable to locate/patch the leaks so I've just sent them back to BC. I switched to a ThermaRest pad that is a bit lighter but thinner and not quite as comfortable. We'll see how well that holds up in comparison.

Helps relieve hip pain

So I actually bought this for my sister...but I've since had to buy one for myself. After using a self inflating thermorest for 5 years, I decided to switch to this sleeping pad for myself and for her as a gift because I noticed a lot of hip pain while I was backpacking even on short 1-nighters. The culprit was my sleeping pad (I'm a side sleeper). Even though it takes more energy to blow it up, its worth getting a comfortable nights sleep. Plus, since its not inflatable its half the size of my thermarest pro for women. Not to mention, my boyfriend wants to upgrade because he has the same Big Agnes but its not insulated and he claims mine is so much warmer!

IT works.

Good for the price. Very comfortable and I found it easy enough to inflate. I never liked inflatables before for fear of being way out there far away and springing a leak from a sticker and then freezing from the cold ground unless one could find a lot of leaves to lie on. But I like this. Comes with a little patch kit. A little bit slippery so if you are stuck sleeping on an incline could be a bit tricky to stay on but haven't tried that. On a flat surface is fine. I will say for someone really big and wide, better get their 25" wide other model but this 20" wide is ok for me at 6 ft and 180 lb.

Nice and Sturdy for Desert Conditions

I've used this on 2 car camping trips and a backpacking trip last week. I love that it rolls up into a compact shape. It really is roughly the size of a nalgene, a little larger, but small enough that you can keep in your pack. It is a bit narrow so if you toss and turn you may end up off the side. I used it to sleep under the stars and is quite sturdy considering I just used a ground cloth and then the sleeping pad with some sharp plants off to the side, I sprung no leaks. The price is a bit steep, but so far seems well worth it for such a sturdy sleeping pad.

Warm and comfortable

I bought this in a petite size for my daughter. She's only 2 years old, but I expect to take her backpacking a lot over the next few years, and I figure she'll have plenty of room to grow into it. We've only gone car camping so far, but this pad kept her warm and comfortable during a late September trip in Colorado, when the temperatures dipped below freezing. The pad is relatively basic, but it gets the job done. It's not the lightest, but the materials seem very durable and it does not make any noise like some other lighter pads. It's also relatively inexpensive for an inflatable.

A Great Night's Sleep

I have used this product for about 14 nights of backcountry and more front country and absolutely love it. This was an upgrade from a thermarest z-lite and there is no comparison. I am usually a side sleeper and slept on this pad comfortably both on my back and on my side.

The ridges hold you in place nicely from side to side, though you might find yourself slipping from head to toe if you are sleeping on a slope.

Durability so far is great, and time to inflate is reasonable.
BigSkyBlue at REI on 08/08/2013

I've only used this pad a few times, but I have been completely pleased so far. First off, I was worried about how long it would take to inflate, but it really wasnt a problem for a small guy. Next, I've never used it in rain, but when I woke up in the morning and everything was covered in dew, this pad wasn't holding any moisture. Finally, each time I used it I was sleeping on the dirt, and I have had no issues with punctures, tears, or rips.
So basically, so far so good!

Really nice pad

Really nice sleep pad for the price. No bells and whistles, just a nice, warm sleep pad. One thing that's difficult to see in the picture is the large rails along either side that keep you centered on the pad all night. Each tub also has some down in it which keeps you well insulated from the ground.
It is a little difficult to get aired up, some people might have to take a break before it's all the way aired up. But well worth the price.
Chicago Dan the backpacker at REI on 09/09/2013

This is my first sleeping pad I've ever bought and used it for the first time on an 8 day canoeing/camping trip in Maine. It was very comfortable and kept me dry even when it poured rain and we got puddles in our tent :) I was surprised how easily it blew up (I'm a 5'4, 125lb 17 year old, I was able to blow it up in about 3-5 minutes each night). It was also very compact once rolled up which was nice. Overall, great purchase!

Having started camping in the 70's in floorless button together Army surplus tents, cotton thin sleeping bags and wool blankets underneath for padding. I have tried a variety of pads and finally gave up tent camping as that pebble always became a boulder at 2 am. This is awesome. Can't roll off of it, cause it is part of the bag. Awesome. Not noisy to sleep on, comfortable, great nights sleep. Can't even feel the pebble. I bought it with the Encampment BA bag. Great combination.

Negative Reviews:

I hate this sleeping pad. I've had 2 of them (I thought my first one might have been a dud). My fiance had one a little while ago also.
Every one failed and failed quickly from a valve issue.
Now, granted, ever air pad is a ticking time bomb, but this one especially. Unless there has been a massive valve redesign project, I'd be wary.
I've had a much better experience with the Thermarest NeoAir trekker. It failed too, but after a couple of years of frequent use instead of a couple weeks/months.

Cmonster at on 06/26/2013

Serious leakage; super bummed

In the past, I've always woken up with sore shoulders and hips from sleeping on my side, so I was in love when I first bought this pad. I slept on it for 30 straight days and it was great for the first 20... the last 10 it did not stay inflated throughout the night. I exchanged it at REI thinking it was a fluke in the product. The second one did the exact same thing for the next 30 days. Super disappointed about this. Returning again to REI...
Eleanor10 at REI on 09/09/2013

Slip off constantly

I've used this product on two car camping trips to hot springs, nc and mt Rogers. Temps in high 30's at night, and is warm with down bag. Also lightweight and easy to pack for car camping. But what good is all that if you can't sleep because the thing is so slippery? It's going back!
Lkk at REI on 05/05/2013

Not a good product!

Not conferrable at all! Me and my husband both got one, and returned both of them!

Great for now, but guaranteed to leak

I've had this product for a couple years now. My wife has one, too. Out of the box this is a great product: it is warm and comfortable. Camping in the snow, I use this pad on top of a short foam pad and it is enough to keep my skinny frame warm. It is also comfortable (thick) enough so I don't wake up with lower back aches, which is what happens when I sleep on just the foam pad. However, after a decent amount of use (maybe 20 nights), I started waking up on the cold hard ground with the pad deflated below me. Then the leak rate accelerated and I would need to reinflate multiple times during the night (great way to annoy your tent mate). I tried repairing it, patching about a dozen small pinholes, but it would still leak. I sent it back to the company, and they were kind enough to send me a new one. Unfortunately, now my wife's Big Agnes Air Core Insulated is starting to leak. I patched it, but I don't even want to use it any more. After my experiences, I'm giving up on inflatable air mattresses. Why have such unreliable gear? Besides the inevitable slow leak, you can't use an air mattress in thorny/desert environments where it might get pricked. And you can't simply throw it down and sit on it during winter snack breaks like you can with a foam pad - especially if you're wearing crampons! The extra comfort an air mattress provides is just not worth the hassle.
So I give this product an average of 3 stars: 5 for the first dozen nights, 1 star for the rest of its useless life.
chichicona at REI on 11/11/2013

Wow, it's slippery!

Did plenty of research and thought this pad met all my criteria (small, lightweight, packs easily, plenty of cushion at 3+ inches). But what I didn't think about was how slippery it is! Sleeping bags are already pretty slippery, so it's an instant slip 'n slide when the bag hits the pad. And the vertical seams of the pad don't help the cause -- for side sleepers, the body contours to the round shapes and can roll right off. It's also really noisy/squeaky. I really wanted this pad to work, but I'll probably return it because I haven't gotten a good night's sleep yet on it.
Tahoe43 at REI on 09/09/2013

Fine, but not Great

I would have expected for the price that the mat would sleep better than it does- The mat does lose some air overnight, and even a small airloss makes the mat greatly more uncomfortable. The mat also takes a good while to inflate- expect to be huffing/puffing for a good 5-10 minutes to get it fully inflated. I wish I had opted for the less expensive, but equal okay air mat that was REI brand- the rep sold me on this one saying it was lightyears better-- so far I don't see it.
SouthernSoul at REI on 09/09/2013

Originally purchased the previous version, and while I loved it, it developed way too many holes with minimal use. I returned it for this version, and have been pleased thus far. Its nice and thick while inflated, providing a pretty good nights sleep; then it packs down pretty small in the morning. No problems after 2 trips; here's to hoping this (blue) version holds up better than the last(brown). Will revise review after my next 2 trips.
