    Q-Core SLX Insulated Sleeping Pad

    Your dirtbag lifestyle may not bring you to many five star establishments, but honestly who needs overpriced, tourist traps when the Big Agnes Q-Core SLX Insulated Sleeping Pad adds a heavy dose of luxury to your camping experience. Made with a ripstop nylon and TPU laminate, the Q-Core is a rough and tumble mat with a minimalist design that keeps its weight to a minimum in all of the available sizes. A layer of synthetic insulation works hand-in-hand with the cozy, quilted top to deliver top-shelf comfort when temperatures down to fifteen degrees, which makes this pad ideal for everything from early spring ski tours and summer backpacking at high elevations, to late fall trips to the desert. 

    • Light, insulated sleeping pad designed for three-season backpacking
    • Laminated ripstop packs small and provides outdoorsy durability
    • High-volume valve allows efficient inflation and fast deflation
    • I-Beam construction reduces weight without disrupting stability
    • WRM HL insulation temperature rated to 32F
    • Item #BAG009X

    Big + Light

    • Familiarity: I've used it several times

    I really love how tall this pad is. If you are sleeping on rocks or roots or uneven ground it is awesome to have a large pad. The further away you can get yourself from the ground the better. I love that this pad is big but it packs down small and is super lightweight. I also love the big flat valves to inflate and deflate. I highly recommend picking up the PumpHouse Sack. Hopefully in the future Big Agnes will just include the PumpHouse and integrate it into the sleeping bag stuff sack.


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

    The weight and size on this pad is exception and perfect for a light backpacking kit. It's also insulated and comfortable. It keeps you way off the ground too, as far as light sleeping pads go.

    I used this in 30 degree weather and was very warm, paired with my Ethel sleeping bag. I was very comfortable and didn't feel a difference between this and my Q-Core Insulated, which is much heavier. Strangely, I think this one is quieter than my Q-Core... Mine is many years old though, so the technology on these may be better, e.g., quieter.

    The only thing I would change is to get the wide version. I have learned that I personally always want a wider pad. I am a side sleeper and often sleep with my little dogs, so the wide pads always make everything more comfortable.

    I found it colder than expected

    • Familiarity: I've used it several times

    I camp high in the Rockies and in August the temps still dip into the 30's at times at night. The pad is comfy for me until it gets below about 40 degrees. When it hits the mid-30's and below, I definitely feel cold coming up from underneath despite my warm sleeping bag. I wish Big Agnes would give an R-value! Their website says the pad is rated to 32.
    Great pad, though, if you don't need a warmer one.

    Comfortable and compact but not warm

    • Familiarity: I've put it through the wringer

    I disagree with the 15F rating. I start to get cold in any temps below freezing. If it will be below 40 then I am going to consider adding a foam pad. That said, it is EXTREMELY comfortable, packs down small, and is very light.

    Awesome pad!

    • Familiarity: I've put it through the wringer

    I stole this pad from my husband and then had to purchase a Big agnes pad for myself! He's been using this pad for a couple of years and it has held up great. It packs down small, it's lightweight and the insulation is nice for cold nights. It does take me a while to blow up, so I got the Pump House to speed things up. However, packing this one up is faster then my AXL air because of the two valve system.

    Great sleeping pad!

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

    I ordered this sleeping pad for my multiple camping trips coming up this summer. I tried it for the first time this past weekend during a car camping trip. The mat comes in a stuff sack that rolls down decently small and isn't overly heavy. I was using a 30litre pack for this trip and was able to put it inside with the rest of my clothes no problem. The weather was cool during the trip, but I was never cold while sleeping on the mat. It rained 2/3 nights and dropped to around 3 degrees Celsius (37 degrees Fahrenheit), the mat also never deflated. I blew it up on the first night and didn't have to touch it until we left. I did have to use my mouth to blow it up which took probably 10 minutes, I will be purchasing the Big Agnes Pumphouse Ultra stuff sack/pump to save my lungs on my next trip. The pad also deflates super fast and the valves lay basically flush so you don't feel them when you're sleeping.


    • Familiarity: I gave it as a gift but have feedback to share

    Upgraded to this sleeping pad after sleeping on my Thermarest foam pad for years. Had no idea what I was missing out on! I can't wait to climb into my sleeping bag at night to rest in luxury atop this glorious cloud. Lightweight and durable material, easy to inflate, and keeps a good layer of insulation between you and the ground. Great product!

    Sleeping like a baby

    • Familiarity: I've put it through the wringer

    I can't believe I waited so long to trade-in my Thermarest foam pad! I'm a side sleeper and this pad takes my sleeping game to the next level. I've never been so comfortable and well-rested after a camping trip.

    Big Agnes - great customer service!

    • Familiarity: I've used it several times

    This pad was working wonderfully, but after 6-8 times use this summer it started to leak overnight and would be mostly flat by morning. Slow leak and I couldn't find any holes to patch. Sent directly back to Big Agnes, and they shipped out a new unit the same week. Great customer service and I'm hoping no issues again (not sure if I popped the bag, or if manufacturers defect?)

    Cushy (but cold)

    • Familiarity: I've put it through the wringer

    Being a little older than the average Backcountry customer, to me a good night’s sleep in the backcountry relies to a large extent on a comfortable sleeping pad. The BA Q-Core SLX Insulated is my pad of choice for warmer temperature backpacking trips. The 4 inch thickness comfortably accommodates my need to sleep on my side, the I-beam construction helps to keep me from rolling off sideways, and the air valves just plain work. Weighing in at a little over 18 oz (including stuff sack) on my scale, the Q-Core is not ultralight but I’ll take a couple of extra ounces for a good night’s sleep. The size regular works adequately for my 6’2” 175 lb frame (I don’t want the extra weight of the larger size). An added bonus – in my experience the noise factor is less than pads made by that other leading brand.

    The downside (and it’s not insignificant) is that this pad sleeps cold in temperatures below maybe 35 degrees F. For a pad which is advertised as “insulated” this is a bit surprising. On colder nights I can actually feel the cold creeping up through this thing and sucking the warmth out of me. It's interesting BA doesn't provide an R-value rating for this pad, but the 15F temperature rating is misleading according to my experience ... hmmm...

    The BA Q-Core is outstanding for warm weather adventures, and I highly recommend it if the 18 oz weight doesn’t put you off. Just don’t be fooled by the word “Insulated” in the description.

    BEST pad!

    • Familiarity: I've used it several times

    I am so happy I decided to go with Big Agnes for my camping needs! I have my sleeping bag, sleeping pads and tent from them and I love them all. I have this sleeping pad in the petite size and it works perfectly with my petite Roxy Ann sleeping bag, my husband also has one in size Wide long and it fits his Big Agnes lost ranger long x wide sleeping bag well! We are always toasty warm and comfortable with this sleeping pads! Super happy with the purchase. It is really easy to blow up and deflate!

    Excellent Pad

    • Familiarity: I've used it several times

    Came to write a review on this pad after a full summer of use, but realized this pad is already super highly reviewed. +1 to all the other reviewers saying this is a great piece of equipment. Light, compact, super comfortable, list goes on... I've been using on some light and fast adventures and thus went with the smallest/lightest variant. No complaints or durability concerns thus far.

    You are going to Love this Pad!

    • Familiarity: I've used it several times

    After using a more traditional ultra-lite pad for years. I recently upgraded to this BA pad. Even before using the pad, I appreciate the selection of sizes available, so I can dial in the exact pad that fits my body and sleeping patterns. This pad is weights under a pound, it's amazingly thick, doesn't sound like a potato chip bag and will inspire envy in all of your tentmates.
    You can't go wrong with this pad.

    Will never cheat on this pad w/ another

      Clocking in at four inches thick, under a pound, compact and durable? Can’t be real....but it is. This piece of gear will help you get off the couch and stop complaining about sleeping problems, being too cold or having to use the aspirin for your back the next day. Always keeps me warm by itself ( but always use a foam pad with any inflatable in the winter) and has held up for the past year in all seasons and surfaces. No more bruised hips from thin pads, and it’s not crinkly or loud. You get your moneys worth and them some. Even enjoy the feel of the fabric.

      Will never cheat on this pad w/ another

      Will never cheat on this pad w/ another

        I’ve had this pad for about a year now and would choose it again without thinking twice. It is very light, very compact especially for its fabric durability and thickness, and an unheard of 4 inches thick! Yes, FOUR INCHES. At less than a pound for the regular size. I never worry about being too cold, or bruising my hips from the ground, or being uncomfortable for any reason pad related. In the winter, like any inflatable pad, you are going to want to put a foam pad underneath to insulate you from snow or frozen ground. Other than that, you’re solid and will never have to worry about this bad little package of lime green comfort. No issues with the inflate/deflate valves, and it holds up against thought California granite .you get your money’s worth with this pad and will be very happy . I have heard someone say they wished it was wider as it comes in at 20 inches , but I’m good.

        Love BA pads

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

        Have only used this 2 nights but its very comfortable and warm. Packs up very small. I have always appreciated that Big Agnes stuff sacks are a little bigger than needed which makes packing up much easier. Really like the newer valve style, faster inflate and deflating. Cant speak to longevity, but as its a lightweight air mattress I don't expect it to be very durable and plan on being careful with it.

        Didn’t Last

        • Familiarity: I've put it through the wringer

        This is my first big Agnes Pad. It lasted about 15 nights. No holes no damage, just stopped holding air. I am going though warranty right now and I will see how that goes. But unless you want to be sleeping on the cold ground halfway through a trip I don’t recommend it.
        My wife has had three pads by them bought one and has had it replaced on warranty twice. They are very comfortable and work well with the intergrated sleeping system but the quality is questionable for the price.

        Is there a pump bag that would work with inflating this sleeping pad?

        Hey Michael - Big Agnes makes a pump bag called the 'Pumphouse' that will work with this Q-Core SLX Sleeping Pad. Unfortunately we do not sell it but you can get it from them directly. Feel free to contact me directly with any additional questions.
