Big Agnes Insulated Air Core Sleeping Pad - Mummy

The pad is easy to use, packs small, is lite, great R-value and good price point. My only problem with this mat is I had used it once and the second time I took it out it was deflated when I woke up. I am guessing I just had a defective pad, I took it back and got a new one and have not had any issues to date. For the price this pad is an incredible value. Obviously I see there are other reviews with the same issue as I have mentioned so there must be something to it, but I have not had any problems yet with the rectangular model I also have by Big Agnes. I think I am going to check out Exped next because the Rvalue on their downmat pads is 8 and the price is not too far fetched.

I own three therm-a-rest pads. The Ridgerest, Zlite, and Prolite Plus. I have nothing negative to say about any of these pads, but I like the insulated air-core mummy better. Here is why My new favorite is the insulated air core mummy.

1. Thickness: At 2.5in thick it is an inch thicker than my previous favorite, makes golf ball sized rocks and mounds disappear.
2. Warmth: My previous favorite had an R-value of 3.8, this pad bumps me up to 4.1
3. Weight: This pad at 21oz weighs less than my previous favorite
4. Packability: This packs down smaller than my closed cell and self inflating pads
5. Price: This pad beats my previous favorite in all of its specs and still somehow costs less. The best part is the fact that the stuff sack and a repair kit are included. My last pad that already costs $30 more than this pad required me to buy a stuff sack and repair kit separately so I spent $130 altogether for a lesser pad.

In my opinion this pad is the best value out there.

i have this pad matched up with my horse thief and i can't think of a better match. i have never been cold, it packs way down, and i have found blowing it up not a problem at all.

Rated down to 15 F. Comfortable in a bivy. Packs really small. Big Agnes makes good pads. Great backpacking pad.

I like the 2.5" thickness of the Big Agnes Insulated Air Core. I can adjust the firmness as with any inflatable, but have more depth to accomodate my finicky back. I'm thin and tall and can finally sleep on my side without the hip bones aching in the morning or touching down through the mattress. Then insulation keeps the air from moving in the mattress so it's warmer. Downside: gotta inflate this baby all the way with my breath each evening; about 25 big breaths, broken up to keep the dizzy head away. There is a 6 oz weight penalty over the winter full length Ridgerest I was using, but it's also lighter than the full length (older) Thermarest Camper I was carrying. Rolls up nice and small - another plus.

I use this pad both with and without a BA bag. Either way, this pad is so comfortable that it easily offsets any effort needed to blow it up. Let the sissies whine about blowing up a pad. When I finish up a 15-20 mile day, I can blow up a sleeping pad without a problem for a great night sleep and be able to wake up and hike even more.

This pad works great to smooth out uneven ground/to make a super comfortable 2.5" pad. Blow the pad up fully, lay on it, then let some air out until you're comfortable or just before you feel the ground beneath (if you feel the ground, put an extra breath in).

In addition, for the warmer nights, lay the maroon side down to get the Primaloft insulation to lay flat. This way there is minimal insulating value and you don't get too warm. And if you do get some chills, simply flip the pad maroon side up, allowing the insulation to hang and do its job. This pad has kept me plenty warm down into the 20's with my BA Zirkel 20 bag.

Not much more than I can cover that the other 5 star reviews didn't. I do not sleep well when not in my bed but this 2.5 inches of comfort really help. R Value of 4.1 means I don't feel the cold ground on my back which really comes into play with the Big Agnes sleeping bags. I leave the pad inside my bag and roll them up together. The only downside is the 5 minutes it takes to inflate this pad.

Makes for a great night's sleep! Does everything it claims to do. Blowing it up isn't the most fun I've had, but it's an inconvenience I'd gladly deal with for a comfortable night.

This is my second BA Air Core pad. I bought the insulated version for colder weather camping. Guess what, it actually weighs slightly LESS than the regular version, at least on my digital scale. This pad is sooooo comfy at 2.5" and does a good job against the cold. It takes me between 17 and 20 breaths to blow it up. Kind of a pain but the good nights sleep is worth it. I'm a side sleeper and my hips are never sore anymore. The price, weight, packable size, and warmth of this pad simply cannot be beat.
As happy as I am with this pad I am disappointed that mine has apparently developed a leak after less than 14 bag nights. It's a very slow one and I can't hear any hissing, I think it might be a manufacturer defect at a seam. I'll be taking it back to the "other" gear store and getting a new one. Would have got five stars otherwise.

This pad is great. It is lighter and packs more compactly than any other pad I have ever owned. But it is also the most comfortable pad I have ever slept on. Almost like being in a bed at home. No more sore hips in the morning.

Bought my Big Agnes Pomer Hoit 0 Degree bag with matching insulated air core sleeping pad. Used the combo for a climb up the remote & seldom climbed north side of Elbrus in Russia end of August, 08. Two wks of use in temperatures to 20 degrees and gale force winds which threatened to rip our tents apart at the foot of the glaciers. The Russian guides were envious while they were cold in their gear and my fellow American climbers were wishing they had the 2 1/2" of comfortable air under their bags. Everyone was surprised by the light weight of the bag/air pad combo. I slept comfortable & warm the entire time. Another plus is having the mattress secure in the bag sleeve so you're not rolling off the mattress.

I love the outdoors, backpacking, climbing, etc. My biggest problem however has always been trying to get good sleep while outdoors. After trying several others I have finally found relief with this pad. It is compact and light enough to use for backpacking, yet still provides enough cushion to allow me to sleep on my side comfortably.

I also love the value that BA provides. For $75 this pad includes a stuff sack and a patch kit. My Therm-a-Rest Prolite Plus cost $80 and I still had to pay an additional $15 for the stuff sack.

I have used this pad snow camping without the use of any other foam pad under it and it worked very good. It also fits in my Bivy sack well....one other thing I like about this pad is that it fits into its stuff sack easy............5 out of 5 stars thanks

I've used this pad on winter trips and as long as your bag is rated, this'll keep. Excellent for bivying, backpacking, etc.
If you don't like to puff (takes approx 40 blows to inflate this sucker), I'd recommend a thermarest pad

slept as low as 35 degrees so far, and it's a warm pad. love it. extremely comfortable, and pliable (as opposed to stiff like other pads). very comfortable even for a side sleeper like myself, and wasn't at all slippery like other pads i've used. takes about 5 minutes to blow up, i did it in a couple shifts with a a few camp chores in between blow up session.. i have the long mummy version, and it packs down to the size of a nalgene bottle, and at 23 oz, it's lighter than older style pads half the size. LOVE IT!!

Prep and thruhiked with this pad in 0 degF cold and kept warm throughout the night. The cut is ample enough for a broad shouldered hiker and this thing fits magically into the BA Horse Thief for your summer bag. I used the regular and I am 5'10" 190 and this thing was perfect for my frame. I blew it up and used it every night for 135 nights. I wouldn't put any Tyvek underneath while sleeping in the shelters on the AT because the material is super tough and definitely not slippery which is good for keeping your bag on top. I will never use another sleeping pad because this thing has everything right. One problem a lot of thruhikers have is not being able to readjust to sleeping in a bed for almost a month because our bodies got so used to sleeping on hard surfaces. I had no problem readjusting because this felt like I was on a bed every night I was out there. Sleep is super important for your body and mind when you are trying to recharge day after day of long 20 milers, this gave me sound and nourishing rest every night. I didn't mind the 5 minutes it took to blow up because I knew what kind of comfort I was getting ready to enjoy. A fantastic airpad that weighs nothing and gives you a great nights sleep.

Honestly i can't say enough about this pad. It is amazingly comfortable, packable, and after the first time you blow it up (15 minutes) it only takes a few minutes every time after. Packing it up is a cinch too, just open it up when you wake up and about 90 seconds later the thing is flat. Fold it in thirds and roll it up to pack it back to the shipping size and smaller than any Thermarest (foam or air, short or long). Great job BA. Also, if you have a BA bag, there is no better system when you get the pad/bag sleeve system going.

nice pad, great weight to comfort ratio. mummy style nice for smaller footprint tents. make sure your lungs are in good shape.

I seriously thought this pad was the answer to my prayers--I used it on a Denali trip and slept better than I ever have winter camping (with a foam z-rest underneath for insulation); it was so cushy and comfy and after all those good nights of sleep I would welcome the three minutes of heavy breathing it required to blow up every night, because it meant I was going to sleep like a baby. But alas, after that one trip it developed a sneaky slow leak that I haven't found yet. I will put it in a bathtub and find the leak and fix it of course but just was hoping for some more durability--I have used Thermarest pads for years and never had a single hole or leak or issue.

I found that I was having to carry two pads, a foam and a thin montbell self inflating pad, to be somewhat comfortable. This pad is great! It does take a while to blow up but nothing too bad. Get this pad to stay warm and comfortable.

This pad is not only simple, it's extremely comfortable and really warm on those certain nights at those cold locations. I wouldn't have expected anything less from Big Agnes.

As for hammock use, I recommend it on cool nights. However, deflate it some so it will conform to your body and reduce pinching along flex points.

I bought this pad to use with a Big Agnes Sleeping Bag as part of their "system" and it works great. I have 3 Thermarest pads at home of varying thicknesses and weights, along with ensolite and other closed cell pads and nothing works as well as this inflatabe. Having it as part of the sleeping bag means you never roll off it, and there are no cold spots either. The only downside is having to inflate it. But that is a small price to pay for a good night's sleep.

I have had two of these (I sold one to my friend after he fell in love with it) and both have served me great. This is the most comfortable, packable, and light weight pad around. I have always stayed warm with this pad. The only exception was one night I spent camping in Swaziland, temperatures were low and my backside got a little cold at first, but that warmed up as the heat in the tent built up. This pad is great, my friends are all getting them too.

Makes me feel a little guilty because I got my wife a therm-a-rest trail at a local retailer and mine's so much more comfortable. Whenever we end up on the same pad on those cold spring nights (he-he) its always the BA, so it can take some abuse too. It doesn't matter if it's 2.5 inches or 10 inches (the pad) as long as you're not touching the ground your floating on a nice cushiony pad of air. 5 Gold Stars.

Last year I used a foam pad and felt every rock during my less-than-restful trip. On recommendation, I purchased this pad and slept in heavenly bliss on 2-3 inches of insulated air. Packs very small and extremely light weight. It does take several lung-fulls of air to inflate.

I bought this to replace my old Thermarest. So far I love it, only thing is its a little heavier than the thermarest but definitely nothing to freak over.

Comfortable but a little hard to blow up compared to a Thermarest. It would be a struggle at altitude. I really like the compact package when deflated. Haven't tried it in cold temps yet. Overall a good alternative to a thermarest if you need a lightweight, compact pad for backpacking trips.

This pad is great. It's very comfortable to sleep on and packs down extremely small. A little lighter than my Prolite Plus and much warmer and more comfortable. Hopefully it will prove to be as durable.

For the first time I have found a sleeping pad I can actually get through the night with no discomfort. I have gone through multiple sleeping pads and would always wake up with my hips sore.

I am impressed it also packs down smaller than other pads I have had, yet it is much thicker once inflated. It also fits back into the stuck sack with ease, were as other pads are a chore to figure out how they fold back up.

My experience with it has kept me warm in 20 degree weather. If it gets colder than that, I have always taken an additional closed cell pad but I may not need it.

I do have a Big Agnes bag for which it was intended to fit, so I cannot say how they work with other sleeping systems. My friend who has the same pad says it works well with his bag which is not a BA. And as for complaints I really have none, it does take awhile to inflate but taking a few minutes to inflate it to ensure great sleep doesn't bother me a bit.

This thing is amazing for sleeping and I am certainly the envy of the tent, but I think it is too big to take on serious backpacking and ski touring trips. Even though it rolls up super small, it is a pain to pack up into the bag sometimes and much harder to inflate compared to the thermarest inflatables. I use this when sleeping at a friends, on the floor of a cabin, or in the back of my Toyota and I bring the thermarest into the woods.

If you don't mind the long inflation time and want the extra comfort, though, this thing is perfect.

I spent a night on this in about 10degree weather and I think it is safe to say it is it saved my but. It really keeps the heat in well.

This is my Second Big Agnes sleeping pad and I am absolutely thrilled by it. I was hoping to sleeping in a Quinzee the other night but couldn't get enough snow to build one (Its cold here but barely any snow yet). So instead I went out onto the lake and set up a tarp. Together with my Sleeping pad and Big Agnes sleeping bag (Yellow wall sl) I was really warm.

The only thing is that the 2.5 inch sleeping pad takes a bit longer to blow up at night and then roll up in the morning. But I am willing to spend the few extra minutes doing that because it is so compact and so comfortable!

Great Product.

I had this pad and I can say that I was not happy with it. I felt like I was sleeping on PVC tubing. I let some air out but was still uncomfortable. I switched to a Big Agnes Two Track and was much happier and more energetic

If you are like me and have a hard time staying in one place all night, you should probably go for the rectangular style instead of the mummy.

I owned this pad back in 2006, and took it out on a snowy Spring day above 10K feet. My first issue was that I couldn't find level ground, and had to settle with a slight downward slant for setting up my tent. I then spent the whole night sliding off my sleeping pad, or waking up with only half my body on this pad. This is mostly a personal problem, but someone like myself should stick to the 'wider is better' version.

I am really happy with this pad. I have used it several times winter camping. I have had a cheap closed cell pad under it and I have stayed extra warm. If I could do it again I would probably not get the mummy style pad unless I had a Big Agnes bag that it fit into. But overall I love the pad, its comfortable and warm.

This sleeping pad is the difference between roughing it, and actually getting a good night's sleep! Getting off the ground, with the built in insulation, allows you to comfortably fall asleep, beginning the first night of your hike, and feel rested when you get up to face the next day;all through your trip. Add in the fact that it is incredibly light and packs really small, and you cannot beat it! You will not regret the investment in this great piece of gear, and you will never go back to another sleeping pad.

Although you might have to huff and puff a few times to get this inflated but it has provided me with back country pleasure for 3 years now. Replaced a Therm-a-Rest Prolite 4 with this and immediately noticed the small rocks and roots disappear in the 2.5 inch pad beneath me. Rolled size is the same as when it came, SMALL!! The insulation is noticeable and helpful but come late fall/winter a close-cell pad is needed underneath. With the closed-cell underneath, I have used this on the snow with great comfort. Mummy cut and long are great for my needs and size.

To top it off, Big Agnes includes the stuff sack and repair kit.

Great purchase at a good price. I had a self inflating pad but this one is much better. I like the light weight, ability to roll up with the sleeping bag and fit into the compression sack, and it was far more comfortable. I never rolled off and bought the long version even though I am shorter. This seemed to be a great combination.

I had the summer version of this pad and had used it many times before needing a cold weather pad for a high altitude trip. I was pleasantly surprised to find that the packed size of this pad was almost identical to that of the summer pad. Not only that, but I also paid a similiar price. From expereince with the other Big Agnes air pad I have found that these are very durable and reliable. I remember using the big foam pads as a kid and I am very happy to be able to fit this in my pack. I have a Big Agnes bag that has a sleeve for the pad and I only spent less than $150 for both items. I am very happy with this pad.

This is a great pad, warm, comfortable and easy to inflate. But if you're a person who moves at all while you sleep.... beware, you will fall off! The tapering at the foot AND the shoulder is too extreme. If I had to do it again I would suck it up and get the rectangle, it's worth the few extra ounces.

Love it. Lightweight and compact!
And the 4.1 R value is the best out there.
I have 2 of these and use them in summer and winter. no issues. Great buy!

The older I get, the more important "comfort" has become in my backpacking endeavors. Packs small and light. Might be a slight inconvenience to blow up, but really doesn't take all that long (5min. or less...), however well worth the solid night's sleep. Used it on the CDT, well above tree-line, with lumps, bumps and rocks everywhere... they all disappeared under the pad. It will be tough to ever go back to other pads, simply not worth the few ounces less. Tried the non-insulated pad, but found the cold came through the pad all too readily, thus moved up to the insulated. Seems durable, and comes with patch kit. This pad got my beloved spouse out on the trail with me, as she simply could not tolerate the aches and pains of sleeping on the ground any longer.

This pad is super comfortable and packs very small. I had been using a self-inflating thermarest, but I sleep on my side, and I always woke up several times during the night because my hips were killing. Not so with this pad! I slept very well. I have a Big Agnes sleeping bag, so it slid into the sleeve, so I didn't fall off the pad.

The only reason I'm giving this 4 stars instead of 5 is because you have to blow it up, which takes several minutes and some dizziness if you don't take breaks. I've heard that too much moisture can get inside it from your breath, so I put my bandana over the blow-hole (not sure if that helped, though).

Overall, a great sleeping pad and definitely recommended, especially for side-sleepers.

I've tried numerous pads and this is by far the best sleeping pad I have. The weight and bulk are similiar to the self inflating pads I have tried.

Until I got this pad, I dreaded going to sleep at night on hikes. I have used this pad in the wilderness at temps in the 30s and was very comfortable.

I also bought the B.A. memory foam roll that this pad fits into. Together they make sleeping in the outdoors more comfortable than a typical hotel bed.

I roll up the sleeping pad and memory foam together and strap it to the outside top of my bag. By itslef, the pad will fold to the size of a water bottle and can be put anywhere inside the bag or side pocket.

This is a very very nice sleeping pad. Only drawback if u can call it that is that u have to manually blow air into it. Not a really big deal... Oh yea, I tested this for a couple of weeks now and i do notice that it does eventually lose air pressure. I'm not too sure if this is the same with all Big Agnes sleeping pads or if maybe i got a defective one? Please peeps let me know.

Thanks, Trey

I don't have an Agnes bag and just put the pad on the ground under my mummy. I don't slide off it. If I don't inflate it all the way it's more comfy for me sleeping on my side. I bought one. Used it a couple times, then bought another one for a another family member. They both work well. It does take quite a few breaths to get it inflated, but it's not too bad.I just went camping a week ago and the temp got down to the upper 20's. This insulated me from the cold ground inside a tent.

I roll the pad up and put it into the provided bag. I then stuff that bag into my sleeping bag's stuff sack and cinch it up. It packs small enough to fit in with the sleeping bag just fine.

packs small, light, and gave me a comfortable cushion. Blowing up the bag was a minor inconvienience.

I really like this pad because it is very lightweight and comfy, you can't feel the ground at all. It's also easy to care for. I used it with a GoLite down quilt that snaps around the bottom of the pad, so you can really keep cold air out.

Warm. Comfortable. Packs extremely small. Blows up easily and quickly. I can now sleep well in the wilderness.

I have only used this once now and it was about 20-25 degrees out. I was not cold at all nor was I sweating buckets. It fit perfectly inside my BA bag and I really like this pad becuase I can just leave it inside the bag if I so choose and stuff the whole thing in a stuffsack becuase putting it inside the bag is really the worst part. It is light as heck, plenty warm, and comfortable as all get up.

This is the nicest pad when it comes to comfort and warmth. I used it on Rainier this past summer, and it was like sleeping on a cloud. I am climbing Denali next year and feel very good about the performance 0f this pad.

Easy to inflate, comfortable and small/light when packed up.

This was a perfect mattress easy to fill up and packs very easy. I fell asleep easy and it kept me warm. I also noticed I did not slide around as much as I thought I would.

Most comfortable air mattress I have ever used backpacking. I also own the non insulated version and recommend against that as I slept cold on it and I almost never sleep cold. The insulated version worked very well for me.

This pad is way above the rest in comfort and value. I have already used it on more than one climb and its the best.

Tried this pad after I returned the clearview due to material. Inflatables are a rather new thing for me as I am used to closed cell pads but thought I would join the rest of the group and get a really great nights sleep. This pad is nice, it kept me warm in 30 degree weather but the pad itself I just find uncomfortable and finicky. Perhaps I just didn't give it enough time, but I feel being 2.5 inches off the ground means that you either have to never move at night or be ok with half your body being off the pad. If it works for you great, for this closed cell guy, the move was a mistake. Returned it due to no fault of the manufacturer. Quality seems tough and durable.

I slept on my pad for about a 3 days, it was relatively comfortable, i mean you're camping so its not like being in bed. But compared to foam pads i've used in the past it is way better.

Temperature wise i could feel the pad pick up heat right away once i crawled into it. The only thing is that the lowest temperature shown on my thermometer was 40F so i'm not sure how it will handle bellow freezing.

I also slept on a smooth surface so i cant say how good it is on a rocky surface, but i will say that my body didn't touch the ground once. It is very thick and easy to inflate.
