    by fromThis thing is great. I'm not an Ultra-Light person...more light weight, but this pad stands out. It is comfortable, light and packs small. I've only used it down to the mid-40's, but didn't experience any discomfort at all. I went with the mummy shape to save a bit on weight...and have no regrets.

    by fromNot as wide as advertised I used a Big Agnes insulated Q core and loved it but it was on the heavy side for long distance backpacking. When Big Agnes put the Q Core SL on the market I immediately ordered it. There's one huge problem with it though. It's advertised to be 20 inches wide....but it's only 17 inches wide. When I lay on it my arms fall right off the sides of the pad! Unless your really thin through the shoulders....don't buy this pad.

    by fromNot for wide shoulders I was very excited about this pad when it came out, and was looking to use it as a significant upgrade to my backpacking sleep system. I was willing to trade some weight for the promised thickness and get a better night's sleep in the backcountry. Unfortunately, it's not wide enough. Mine measured just under 17 inches when inflated, not the spec'd 20. Not good for a guy with wide shoulders. It weighed in slightly over advertised by an ounce or so, I don't really remember as I ended up returning. That being said, it was comfortable and easy enough to inflate.

    by frommeh, it's ok I decided to start a bike trip that ended up lasting 6 months starting in July so I bought this mattress as it seemed to be the greatest invention since peanut butter and I slept on it every night. The first few months were great! It packed down smaller, was thicker, warmer, and full length (major upgrades) compared to my previous half length self-inflating pad! Also, it is thick enough to sleep comfortably on ANY SURFACE even if it is uneven or rocky. Even inflating the mattress wasn't difficult, it was more or less an excuse to work on relaxing breathing exercises after a day of riding. I didn't find any issue with slipping off the pad while sleeping even on non-level ground, everything would slide as one mass to the lowest spot in the tent. So, the pad is a bit slippery on the tent floor. AFTER A FEW MONTHS of every day use, I realized that peanut butter is still the greatest invention. I didn't mind which side I slept on until I started noticing black dots forming on one side (some kind of mold maybe?), so that side became the ground side. These dots could not be cleaned off! I did not use chemical cleaners as I did not want to damage the material. The problem with inflating this mattress is not just that your breath causes unwanted moisture, but also that it contains nutrients from the food you eat. I began noticing something squishy inside the mattress and it grew quickly. I flushed the inside of the mattress with a solution of rubbing alcohol and salt, expecting that to kill just about anything, but the physical mass of the biological growth was still there and would not come out. I made a new salt/alcohol solution and left it in the mattress to prevent any future growth. I don't know how much extra weight grew inside, but it was disgusting! Eventually, the mattress started deflating over night. I thought, well, its just cold outside causing the air to compress (I could not find a puncture). Travelling continued and the mattress would no longer hold air for more than an hour, surely there must be a puncture! The punctures were so small that I could not see them until I filled the mattress with water and discovered several leaks on both sides of the mattress. I marked the leaks, drained the water out, and set to making repairs. I tried to repair one side at a time but found out that the patch material curls into a cylinder once it contacts the glue and I had to repair one leak at a time, pressing and holding the patch in place until the glue was dry enough to keep the patch from curling (roughly 20 minutes per patch). Even after the repairs, it still does not hold air. Were these small holes even punctures or just tears in the material from being used? I definitely spent good time each night to make sure I was not laying the mattress on anything sharp or pokey. I have no idea where it is leaking and I am not going through the hassle of filling this thing with water again. I gave this mattress 3 stars because it was absolutely incredible for a while and I realize that I was using it more than its "super light" capabilities were probably designed for. But, honestly, it could use a few upgrades like a super durable and thick bottom side with markings telling you which side to sleep on and which side should be down. Perhaps include some thin rubbery grips on the bottom side (though these can be made with duct tape). Also, a pump! Or at least an attachable valve to let me use my bike pump. I just stumbled across the Therm-a-Rest NeoAir XTherm. It is in the same price range as this mattress and seems to have the 2 major upgrades that would make this mattress worthy.

    by fromNice pad, but be mindful of specs As noted in another review, it is narrower than advertised when inflated. Might be to spec when not inflated... I haven't checked. I'm thin and sleep on my side, so not a problem Also, mine measured 2+ ounces heavier than spec, even without the stuff sack. Other than that... very nice pad.

    by fromUpdate after using the pad for a while This is the most comfortable "ultralight" pad I have used. Not the lightest, but more comfortable than the lightest. It sort of cradles you so the pad doesn't get out from under you at night. I'm thinking it's worth the extra weight for most trips. It does measure 20 inches wide deflated and about 18 usable inflated.

    by fromGreat ultra light pad with two small negatives This is my second BA air pad, I also have the Insulated BA Air Core. Both are Mummy cut. I got this one because it was 1 inch thicker, slightly lighter, but less bulky by almost half with a better R rating. I really like it for all those reasons. It makes a great ultalight pack for those who want to have a comfortable place to lay down after a long day. Here is where the negatives come in. It is expensive! OK, so what. You get what you pay for, usual. Second and more importantly it is very slim in the solders. I am 5'7'' 155lbs and my arms tend to hang off the sides. It is not a deal breaker just kind of annoying. Over all I would recommend it if you are looking for ultimate comfort and the lightest weight and bulk
