"Back" to comfort

  • Familiarity: I've used it several times

I thought my backpacking days were over, but after finally securing an awesome chiropractor and socking some $ into this sleeping pad, I can finally say that I can backpack again (and not be grumpy after a horrible nights sleep). My lab loves it too because she has now inherited my old therma rest pad and we don't have to fight over it during the night anymore...

I am 5'7"/160 and got the regular pad and its the perfect size. It packs down SO small into the little carry bag, I can put it in the exterior mesh pockets of my pack or anywhere in my pack, it no longer matters. The comfort on this thing was instant (I actually fell asleep on my hardwood floor trying it out). I recommend not filling it up completely but enough your hips don't sink to the bottom and found that's most comfortable. The pattern of this pad keeps you from feeling like its an air mattress you might roll off of and keeps you in place better. I have slept on dirt ground, flat rock, even round river rocks and this pad has the same comfort regardless. No more searching for the "perfect" tent site anymore, now we can camp where we want/need.

I paired it with a Big Agnes sleeping bag, and for someone who likes to move in her sleep and rotate around, the sleep system keeps everything in place. This is one of the first "luxury" items this 30-something outdoor lover invested in to keep my future backpacking years enjoyable.

Even though I would not consider the pad super ultralight, I am a side sleeper and I purchased this sleeping pad after hearing rave reviews given its 3.5 inch thickness. I thought it would be my "luxury" item on the trail. For whatever reason, the pad I received was dead on arrival. Didn't realize it initially because seemed comfy and inflated fine. However, when I actually left it inflated for a few hours, I found out at an inopportune time that it actually had a slow leak - probably from the valve. Continued to be a problem even if I tried to tighten it down. I probably just received a dud but because this has been so frustrating and the weight is between 1-2 oz higher than advertised had been hoping to exchange it for another pad, likely the neoair xlite. Since I realized this issue about a month and a half after my purchase, backcountry has refused to take it back because they said I "used" it. Really disappointed in backcountry's customer service.

Initial Impressions

  • Familiarity: I've used it once or twice and have initial impressions

Finally upgrading from my 6 year old big agnes pad. This is a great upgrade packs up small, it's light, and it was noticeably warmer than my old pad. It is a little more "crinkly" sounding but I can live with that. Will update after some winter use.

Best Night Sleep in the Mountains

  • Familiarity: I've put it through the wringer

For years I slept on self-inflating pads and just figured that a bad night of sleep with a sore shoulder was par for the course when camping. Then I got the Big Agnes pad for a two week camping trip in Alaska and I loved it. The pad feels just as comfortable as my bed at home, and it's not as noisy as other pads I tried out before purchasing this one. The only two down sides are 1) the tedious act of blowing it up compared with Nemo or Exped pads which include pump systems and 2) at 20 inches wide it seems a bit narrow. This last point doesn't bother me, but it's something to think about if you're looking to buy this one. You may want to go with the 25 inch wide pad. The Q Core SL is lightweight and it packs up into a small size (and actually fits back into its bag). It's a great addition to my backpacking gear when weight is a consideration. I highly recommend this pad.

Hey mao5434015,

I am sorry but we are not back ordering this item. However, you are in luck! We do have an order coming in of regulars. It should be on the site by early September.

Trying to decide between the following pads:
1.Big Agnes Q-Core SL Insulated Sleeping Pad
2.Big Agnes Insulated Q-Core Sleeping Pad
3.Therm-a-Rest NeoAir Trekker Sleeping Pad
4.Therm-a-Rest NeoAir XLite Sleeping Pad

Can anyone shed some light? Lightness, packability, and comfort, price?

Best Answer Responded on

Hey Adoraeleven,

The Lightness (weight), Packability (rolled size) and Price are all listed in the tech specs for each of these products. As far as the comfort, I would list them in this order:
1.Big Agnes Insulated Q-Core Sleeping Pad
2.Big Agnes Q-Core SL Insulated Sleeping Pad
3.Therm-a-Rest NeoAir XLite Sleeping Pad
4.Therm-a-Rest NeoAir Trekker Sleeping Pad

If you have any questions at all please either chat in or give one of our gearheads a call and we can help narrow down your selection.

I went through a similar search recently and actually ended up getting the Therm-a-Rest NeoAir Xtherm - in part because of its versatility for winter/colder weather camping too. I considered the same pads on your list as well as the Therm-a-Rest NeoAir All Season. In the end I settled with the XTherm because it seemed to have the best of all worlds for myself.

I get cold easily so I figured this was a good compromise as it is lighter and rolls smaller than than the Big Agnes Q core series (regular Q-core or Q-core SL!) and warmer than either of the Q cores too. It was only slightly heavier and largerthan the XLite - and much warmer/more versatile.

I spent a lot of time laying on both the Q-core and the Xlite and Xtherm - I found the Therm-a-Rest X-pads to be more comfortable than the Big Agnes pads - but that's all really a personal preference thing. I don't think you can go wrong with either the Q-core pads or the Xtherm/Xlite pads. The NeoAir Trekker is a reasonable option as well - priced lower, but doesn't pack nearly as small and is much heavier - thus I avoided it.

Yes, the only variant that is not 20 inches wide is the wide version at 25 inches and the petite is 66 inches or 5 foot 6 inches long.

Cut weight and sleep great. *UPDATED*

  • Gender: Male
  • Familiarity: I've put it through the wringer

Re-Update: Big Agnes has fixed the issue with the 2013 fall printing of the Q-core SL Long. The pad was two inches too small width wise. They have fixed this issue and replaced my pad. The pad is a five star pad.
I decided to upgrade my 09' chambered air core sleeping pad to the Q-core superlight and here is what I noticed.

In terms of weight, roll size, warmth, and overall comfort, this pad is the real deal. I've never owned a pad inflatable or otherwise that had such a complete package.
That being said I did notice that depending on where you distribute your weight on the pad it will shift beneath you, it is not as firm as previous big agnes pads. Personally, I enjoy a firmer pad, but that is just me.
Fixing a puncture is easy and can be done in about 20 minutes, the only problem is you need a body of water deep enough to submerge the pad in, I have done several backcountry repairs on Big Agnes pads, and its fairly easy just so long as it was a puncture and not a tear and that you have water to submerge it in. I don't recommend this pad for extended stays in the desert.

-compact when rolled
-great insulation
-incredibly comfortable

-not as firm as a chambered pad
-punctures somewhat easily

Big Agnes has fixed the issue, and replaced my old pad. There customer service is excellent.

So after my first time snow camping, I've...

So after my first time snow camping, I've come to the conclusion I'm in need of a new sleeping pad. I've been reading a little about R ratings and trying to figure out what will best suit my needs. I think something that could be comfortable from 0F up is what I'm looking for. Any suggestions?

Best Answer Responded on

Hey tyler,
this pad should work just fine for you. the other one I would check out is the thermarest all season or the xtherm

Worthy technology upgrade

  • Familiarity: I've used it once or twice and have initial impressions

It folds easily into the bottom of your pack and makes your buddy's z-lite or self-inflating pad look like a ground cloth. It's a worthy gear upgrade with only two trade-offs that I've found thus far:
1) Inflating it takes time and energy. The Big Agnes Pump House makes it a little easier.
2) I can't turn it into a chair like my old Thermarest Prolite (maybe BA will come up with a solution to this?)

Beware BA's measurements. The largest Q-Core SL is only slightly wider than my old Regular Prolite!

Responded on

Interesting because I have the regular Qcore W/L and actually thinking about upgrading to sl W/L to save a couple of ounces....

Do you have info for q-core vs. SL width?

Incredibly comfy

  • Familiarity: I've used it several times

I heard about the original Q-Core last year, and almost bought one just based on the comfort alone, but heard about this SL version coming out. Waited, and glad I did, for several reasons, although I am a bit disappointed.
I originally went with the regular sized pad, and although light, durable, and really comfy, it was just too narrow. It was about 17.5 inches wide inflated, like other reviewers have stated. I didn't want to believe what other had said, but it's true, it's just too narrow. I'm not a big guy, 5'10", 165lbs, but my elbows hang off the pad, which usually isn't a big deal, but when the pad is close to 4 inches from the ground, it feels weird.
I contacted Big Agnes to see if they had plans to correct the issue, and they said they don't, although they were more than happy to take it back and give me credit for it towards something else. I opted to do it through backcountry instead, and got the Long/Wide version on sale at 25% off. HUGE difference. Although I don't need the length, the width is super nice. Sure, it's 5 or 6 oz heavier, but I'm not into the UL or XUL thing, so it works. I have a 16oz Thermarest pad I can use if I feel like conserving weight, but this thing is ridiculously comfy, and really wide. I've used it a few times, and it's fantastic. Very pleased, although at regular price, $220 would be pretty steep.

This thing does what it's supposed to.
Now my encampment is truly a 15 degree bag.
Almost too comfy. I didn't even want to make coffee.

I have the Original Q-Core and it is 20 in wide inflated. I measured a Q-Core SL mummy and a new Insulated Air Core mummy and they were both right around 18 inches inflated. I will say I have the BA lost ranger and the original Q-Core barely fits the sleave. The smaller footprint on the SL might actually work better with system. I am going to contact BA and inquire.
Answer from BA: Yes the Q-core SL is not correct in size and weight. It is actually 1-2? smaller width and length depending on model and weighs 1-2 oz heavier depending on model.
This is something that they realized after production and they are aware of it. If anyone has an issue we can cover it with our returns but BA will also help out any customer that is upset.

Responded on

Is BA planning on fixing the issue with later products, or just adjusting the specs? I bought this pad, and I'm not a large person, so I fit on the pad just fine, but if they're planning on making it bigger to fix the specs, I'd rather get a larger one...

Responded on

It sounded like they had not decided how they were going to proceed. I would not expect a new model any time this season. If you like the pad I would just stick with it. It is still a great product.
