Comfort without warmth | |
| Rating: | |
| I used the Mummy air mattress from Big Agnes in two situations: car camping in the Plains (June) and backpacking in Colorado alpine country (August). It is very comfortable from a padding perspective, compact, lightweight and inflating is really not much of a chore. I had some concerns on the effort required, but it is not a problem. The drawback of this pad is that it does not provide the thermal comfort the rating suggests. I used it with the Big Agnes Lost Ranger down bag, designed with the sleeve for the air pad. In the plains I was totally comfortable, but in the mountains I was cold sleeping in just my underwear. I had to sleep with clothes to avoid getting chilled, and this was at temperatures in the 40s. Rating of the bag and pad are to 20 F, which is just not a valid evaluation. If you don't need the warmth, this is a great product. But if you sleep cool or will be in chilly weather, take other precautions or use a different product. I intend to experiment with supplementing this air pad with a layer of closed foam. The padding comfort is too good to just give it up. | |

Love it | |

| I spent a bunch of time researching sleeping pads before I bought this and I am very pleased with the purchase. Everyone kept telling me to get the thermarest prolite 4 but an inch and a half of padding just didn't seem like enough. This pad weighs less, has a higher R value, is an inch thicker, and packs down smaller then the prolite 4. And for durability, so far I've beat the [*] out of this thing and it's working just fine. Oh yeah, and it comes with a repair kit and a stuff sack. Two luxuries the prolite 4 lacks as well. This pad is also [$] cheaper. If you just absolutely can't stand spending 2-3 minutes blowing up your own pad then buy all means buy the more expensive pad with less features. If you want to sleep like a baby (which I definitely do) and carry less weight then buy this pad and enjoy it as much as I do. | |

comfortable, but not terribly warm | |
| Rating: | |
| i got this pad mainly for the thickness to keep me off the ground. it serves this purpose well. like the description says, it rolls up to about the size of a nalgene bottle so it's nice and small in my pack. a repair kit comes with it, in a pocket in the stuff sack so that's nice. so far i haven't had to use it. my friend has the same one too and he hasn't had a problem either. i think the reviewer that had a leaking problem probably got a bum pad. my only complaint is that it really doesn't keep me all that warm by itself. i have found that if i also use one of those cheapo thin foam pads with it, i'm pretty warm. those pads weigh practically nothing so i don't mind strapping the extra bulk to the top of my pack. | |

Light and Very Comfortable | |
| Rating: | |
| Getting a good night’s sleep is very important after a long day on the trail. I am willing to carry a few extra ounces for that. This is about the same weight as the other pads that I own and I don't wake up felling like I was hit by a truck. It also absorbs the rocks and roots so that I don't have to. I have not noticed any thermal issues. I backpacked in RMNP for two weeks during late June and early July and slept warm. I have spent about 30 nights on this pad. It does not leak and I have not noticed any wear issues. Like the other Big Agnes equipment that I own it is well made and I am very happy with it. | |

Good, but the rectangular one is better | |
| Rating: | |
| I really love the combination of thick padding, decent insulation, and small packed size / weight of this pad. It is way better than any self-inflater if you don't mind blowing it up every night (which only takes a minute). That said, I slept on this pad for a year or so before I replaced it with the rectangular version. Why? The rectangular version only weighs 3oz more, fits better in a 2-person tent with another pad (covers more floor area) and the mummy version has to be folded strangely to get it to work with the Big Agnes camp chairs. In all, it is a great design, but the benefits of the rectangular version are worth the 3 extra ounces. | |

Best Niight of Sleep Ever! | |
| Rating: | |
| Here's the scoop. I picked up a Pacific Outdoor Equip pad and it leaked the first night out. Went back to the store [...]. They steered me in the Big Agnes direction. And if you are interested in a lightweight, compact, DURABLE yet comfortable pad this one is the ticket. I actually got this pad for my wife and the long version (non-mummy) for me. The knowledgeable staff took it one step farther and sold me on the memory foam pad for my wife. She was amazed; having been camping for over 30 years, she had never slept better. Kudos to REI and BA! | |

Big Agnes insulated air pad | |
| Rating: | |
| I've used this pad over 30 nights--including a bike trip into Montana and for 9 nights in the Wind Rivers. It was very comfortable and warm down to 13 degrees with a good down bag...no doubt the best sleeping pad in this weight range I've used...seems very durable so far. There are no cons in my opinion. | |

Nice idea, poor execution | |

| Purchased for ultralight backpacking ~ 2yrs ago. I find inflatables offer great support - I must sleep on my side, need a thick pad and have found the best way to use it is to inflate about 3/4, then lie on my side and bleed out air until my hips almost touch the ground resulting in uniform support. I find it as comfortable as a high tech bed and compact enough to carry as a back up for general travel. Cons: 1. Ours is fully 4 oz. heavier than advertised. The company representative blamed batch variations in thickness of the urethane coating and offered to replace it, but suggested trying it first. I took it out a few times, but later when I wanted to exchange (and complained about the valve) it Big Agnes didn't return my e-mail. 2. The valve leaks occasionally. I believe it gets jammed with loose insulation and have always been able to clear it by opening and blowing forcefully. 3. It's cold, considerably more so than a thin closed cell pad and the cause of one very uncomfortable night in a down bag on cold ground. The reason seems to be that the synthetic insulation is thin and flat and cut narrower than the width of the inflated tubes. One can observe this by directing a bright lamp from the opposite side (like candling an egg). It's stored unrolled, we've tried fluffing the insulation with the bag partially inflated, and once kept it inflated and slept on it frequently at home for several weeks but the insulation didn't expand much, if any. We have an InsulMat pad with the same insulation problem. For temperatures below the 50's we augment with a closed cell pad, which works well and provides back up in case of leaks. We haven't tried a down filled inflatable, but that's a logical next step. We haven't tried it, but as we carry closed cell foam pads for warmth and leak insurance anyway, it might be as good to use the non-insulated version saving $$ and weight. | |

Durability An Issue | |
| Rating: | |
| I agree that the Big Agnes pad is light, compact, insulates well, and way more comfortable than any 1.5 inch thick Therm-A-Rest. But none of that matters when a pad fails after one night of use. I have 5 Therm-A-Rest pads of varying sizes and thicknesses. Some that are 20 years old! Not one of them has ever failed. I was really excited to use this brand new Big Agnes pad on a trip to the Sierras. The first night, the pad was great. During the day, I used the pad in conjunction with the Big Agnes Cyclone SL chair (that broke also). Somehow, using the pad with the Big Agnes chair caused a leak, and the pad failed the second night. I spent a restless night on hard ground. I did not use it roughly, or subject it to unusual abuse. Gear that has to be babied is unreliable. It simply is not durable. I returned it, and will give the Pacific Outdoor Equipment Ether Thermo 6 a try. Dimensions, price and weight are identical (but the insulation factor of the P.O.E. pad is higher). With regard to complaints about having to blow into these pads to inflate. Please, if you can hump a moderately heavy pack up a mountain trail, it shouldn't require superhuman effort to puff some breath into a sleeping pad! | |

plus and minus | |
| Rating: |  |
| This product is great if you want a pad that is very light and has alot of cushioning. However be aware that it does take a few minutes to blow up, which I was willing to do for the 2.5 in. of comfort. I would not recomend this pad if you like to sleep under the stars the puncture risk might be too high, but I have used it in a tent for many trips and never had a leaking problem. Also, when using in a tent it squeaks when you move around. I solved this problem by buying some cheap fabric and sewing it so the pad slips inside, this also makes it more comfortable to sleep directly on the pad during warm summer nights (you get less sweaty). You could also just place a thin sheet between the tent floor and the pad. I continue to use this pad because the comfort and weight are such a plus, but it took some imagination to work out some of the issues. | |
