Sleep like at home, seriously.

I purchased two of these pads for me and my partner in crime a couple of years ago and glad I did! The wife no longer equates backpacking to sleepless nights! This has made a huge difference on the number of trips we take into the backcountry. There isn't even a comparison to closed-cell foam pads in my opinion. I have camped almost all my life and after the first night on an air mattress, I wondered why I hadn't thought of this before! I live in the southwest and the lowest temp I have used this pad in was into the low 30's and we did supplement with foam underneath. They are so light, we didn't even notice the extra weight. Travelling with my wife has definitely influenced my choice of gear and as any married man knows, as long as she's content, life is bliss! The Air Core allows for adjustments to how firm or soft the pad is and while I've never slept on one of those number beds, I imagine it is similar to this. The Big Agnes Air Core does only get 4 stars because it does take a bit of effort to inflate and I DO inflate both pads at camp. (see above statement.) To me, this is an obvious and totally acceptable trade-off from the foam. Perhaps someday, I will be able to squeeze the dinero out of myself for one of those self-inflatables, but I doubt it will be anytime soon seeing as how Big Agnes even threw in a patch kit with each pad. I have been very pleased with the purchase of these pads and can recommend this product for those looking for better slumber outdoors. On a side note, we use these pads with the thermarest ventra system so I cannot comment on how well a sleeping bag stays on and such.

Awesome, comfortable pad!

Definitely a great pad! I had the older version of the Air Core for the past few years. It was also a great pad at 2.5" thick. Unfortunately after organizing my gear one of my cats got into it a bit. I did not notice this until inflating it on a winter overnight... fortunately I can also vouch for the patch kit! Very clear instructions and the patch held strong for the rest of my trip.

I decided to exchange the old pad for this one and was impressed to see that they increased the thickness to 3.25" for even more comfort and adjustability. I have taken 2 early season winter camping trips with it and it has kept me warm even when it dropped to the teens, camping on snow overnight. For what its worth, we did have a layer of pine boughs under the tent and my sleeping bag is rated for 20 degrees. Like the other reviews, it does take a few minutes to blow up, but if you take your time getting winded can be avoided. Very impressed with this pad! It is nice and light and packs up very well.

This is a great product for backpacking in warmer weather, when the temp drops to below freezing it begins to get a bit chilly without something else between it and the ground. I own an older model of this (about 3 years now) in the shorty version and it works great for keeping my shoulders and hips comfortable, it's even comfortable when lying on my side. Another thing I like is that I fit well on it (I'm 6'10") with head to tail comfortable and just throw my pack under my feet to give some pad and insulation there. It packs smaller than a Nalgene and weighs less (as in half the weight or less) then a full water bottle. This has traveled through the backcountry of Colorado, Utah, and Oregon and across southern Europe with me and still hasn't had any punctures to repair so I'm very pleased with how durable it's proving to be. Over all, a great product that I would definitely suggest.

great pad! can be a little noisy

I really enjoy this sleeping pad. Very thick and cushy. I even slept on it while it was lightly snowing in the rocky mountains near Mt. Evans and did not get cold (20degree sleeping bag though). It takes me about 16 full breaths to blow it up and that can be a chore if your at altitude. This isnt much of a problem though for the weight savings. Mine is the shorty and weights 15oz. with the stuff sack and repair kit it comes with. It is very easy to repack into the stuff sack and is tiny compared to the self inflatables. I love this sleeping pad and have had no problems with it myself.

Others that i camp with have mentioned that it can be kinda noisy when i move or roll over in my sleep. this doesnt bother me though. so make sure your campmates understand there not at home in a super quiet setting.

Best night sleep in the woods ever!!

My husband and I enjoy everything outdoors and especially camping! We backpack with minimal necessities, however, he is somewhat of a snob when it comes to the comfort of his sleeping arrangements! We have tried several different sleeping pads from the roll of foam variety all the way to a self inflating queen sized air mattress..ya.. I finally came across these air mats and they are amazing! They roll up so small and light weight and take up almost no room in your pack.
They are made of durable material and can stand up to ground or bunk camping. And most importabtly they are very comfortable. I'd say the only con would be that you have to blow it up yourself but it took no time at all, about 3 minutes.

super lightweight & comfortible

I bought the short pad so it only weighs 15oz with the stuff sack and repair kit. This pad is really comfy at 3.25 inches thick and takes about 15 full breaths to inflate for me. This can be a chore at 12000 ft elevation. I am able to easily repack it into its very small stuff sack for backpacking. I have only used it for 3 trips now so I cannot speak to its durability but I treat my gear well and don't see that being a problem.

I feel this was one of my better purchases it was cheap compared to other pads of similiar weight and size and was a huge upgrade. Freeing up space in my pack and shedding weight.
Justin N at REI on 06/06/2013

Loved this sleeping pad. Bought it as a companion to my Nemo Astro sleeping pad that my wife uses. Used it for the first time on a 10 day camping trip up in Banff and the 3.2 inch thickness certainly made the difference in my sleeping satisfaction. Rolls up super small, smaller than a nalgene I believe. I went three nights on average without having to put another couple of breaths in to pump it back up to full inflation. The material is also a little thicker than my Nemo pad which just makes me trust it that much more. Now if only I could figure out how to stop drooling when I sleep in a tent and I'll be set!

Great First Sleeping Pad Experience

I've always slept without a sleeping pad, mainly because I've been too stubborn to buy something. This first experience was great. I was the envy of my camping mates who all had much more bulky, less comfortable pads.

I had no issues with loss of air, and blowing it up wasn't all that bad.

The item was as described, coming packed to about the size of a Nalgene bottle. And it wasn't difficult to pack back up to the same size!

Overall, I found this item to be great for the money and I look forward to more camping trips with it!
Wahoo 2009 at REI on 09/09/2013

good enough

I agree with most reviewers. This pad is comfortable enough for backpacking, but not luxurious. If you're short on wind or at altitude it takes your breath away filling it up. It folds up to a nice packable size and weight, and fits easily into a pack. If you toss and turn a lot you will notice how noisy these pads are. I would be careful of sharp objects around this pad. I ranked this four stars and not five only because of the noisiness and the need to blow it up.

Perfect for airport layovers

I live overseas on Kwajalein Marshall Islands. Flying back and forth from the east coast we have many long layovers at airports. It is compact and light weight to fit in your carry on. This matress is perfect for just that reason alone. Arriving at Honolulu airport a 3:00am there is no place to get comfortable. This will make the 4 hour layover much more relaxingand tolerable. It will also make other Kwaj folks that are traveling pretty much jealous!!!!

Negative Reviews:

Not for wiggly side sleepers!

My boyfriend and I both bought this sleeping pad, and tried them out for the first time camping in Puerto Rico. I absolutely could not stay asleep on mine. I move around a lot in my sleep, and every time I tried to roll over or adjust, I woke up. The outer ridges of the pad are designed to keep you on your pad (so the REI employee explained), but for me, it was too constraining. I also found it difficult to get comfortable sleeping on my side. I returned mine for a flat model as soon as we got back. My boyfriend, on the other hand, loved his and slept well -- he sleeps on his back and doesn't move around through the night. If you're a side sleeper or move around in your sleep, I would recommend against this model.

Comfortable but leaky!

Leaked from inflation valve from new. Initially it was a slow leak, but got progressively worse. During a 14 day backpacking trip it leaked to badly I would 'hit bottom' 3 to 4 times a night by the end of the trip. The leak was in the valve assembly so it was not repairable. Perhaps I was just unlucky, but I would be leery to buy another one. I got a different brand to replace it.

Leaked from the get go

I have another Big Agnes mattress and it is great! I would like to think its a quality control issue. I will be hesitant about buying this mattres again.
Zobers at REI on 09/09/2013

Neutral Reviews:


This pad gave me a slight backache, but my biggest complaint is that it is very noisy. If you move around a lot and are a light sleeper, this pad will wake you up. It's not extremely comfortable, but comfortable enough. I will keep using it but would not buy another.
