    Five star sleeping.

    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. The pad inflates quickly thanks to a high-volume valve that can be adjusted to the perfect firmness with a micro-adjust, air pressure button. Additionally, the Q-Core SLX is equipped with an antimicrobial treatment to reduce odor buildup.

    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.

        Love this sleeping pad

        • Familiarity: I've used it several times

        I have used a thermarest for the last 3 years and honestly thought that i just wouldn’t sleep well camping/backpacking ever. I roll off the pad, sleep on my side and belly and would wake up achy. My husband has the core q and loves it. When i found this version on sale I bought it. It is a truly amazing change in the quality of my sleep now. I have used this on 3 backpacking trips since its purchase and I will never go back to a thermarest. The side rails are perfect so i dont roll off my pad, the width is enough to where i can sleep on my side without my shoulders hurting. Would definitely recommend this product. Paxks down to the same size as my old thermarest

        Small in the Backpack, Yet Comfortable

        • Familiarity: I've used it several times

        I bought the long and wide version of this pad, and ohhhhhhhhhhh man its like the easy boy of sleeping pads. A lazy-boy that fits into the palm of your hand, that is. Packed up, this thing is tiny at about 12x2, but its still really comfortable all blown up. Definitely pick this one up if you are looking for a new pad!

        Simple functional and comfortable

        • Familiarity: I've used it several times

        For the longest time (5 years) I had a heavy thin camping pad that certainly did the trick but, it was time to upgrade and I am very glad I upgraded to the q-core. I decided to purchase this pad versus others due to the tough material it is made of and its insulation. I don't always sleep in a tent and I feel comfortable putting this on the ground with a light ground sheet without it ripping. The insulation allows me to sleep comfortably on the shoulder seasons without loosing too much heat to the ground. Big Agnes put simplistic technology in this pad without compromising weight or comfort but producing an extremely functional pad for any outdoor pursuit.

        Long and wide for ultimate comfort

        • Familiarity: I've used it several times

        I live outdoors and travel full time. All of my favorite pastimes require top gear with low weight. This pad has been a great upgrade for me. It is smaller than a 1L nalgene when packed away, weighs next to nothing, and the added insulation makes for a cozy night of sleep through all seasons (with the right sleeping bag). Years ago I had a down insulated Exped pad that was great until it started leaking air from a seam during a winter camping trip. I was scared away from air pads and have been using a Thermarest trail pro for a while, but I hated that it did not compress much. I am also a die hard side sleeper so the Thermarest never quite made it to 5 stars for me. This is where the Big Agnes saves the day. It seems much more durable than my old Exped pad, saves a ton of space in any bag, and provides a very comfortable sleep surface.

        As a person who always wants comfort, quality, price tag, and weight to be intersect I highly recommend this pad. You should also get the pump house ultra! It helps blow this thing up in no time. It also steals the show by moonlighting as a dry bag, stuff sack, and outdoor shower. Cant go wrong with multi purpose gear!

        q-core slx pad

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

        Coming from a large bulky foam pad, this air pad makes backing packing so much more enjoyable. The high volume valve makes it easy to inflate. The pad inflates to 4 inches thick and when rolled up is the size of a large water bottle.

        Solid Pad

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

        Just picked this bad boy up! Initial impressions are high for this pad over previous Big Agnes pads. The flat valve design should prevent the leak issues that I've had in the past with thier pads, as they become weaker around the valves. From a comfort level I couldn't be more satisfied. Super kush design and the raised edges deter you from tossing and turning all night long, and having a more restful night out under the stars. Solid pad, but a little too insulated for me to use during the warmer months. I'd recommend this to any camper, and people who like to be nice and toasty while sleeping.

        Livin' That Cushy Lifestyle

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

        It's really darn comfortable, guys. Definitely my favorite sleeping pad I've used to date. I really appreciate the in/out system so that you can get your pad to the perfect level of inflation. Nothing is more infuriating than trying to inflate a pad with escaping air. No need to worry about that with this product. Deflating is super fast and hassle free as well. All in all, just a great system they have worked out. I've only used this for car camping so far, and sure it might not be the lightest pad on the market for backpacking, but it's certainly not the heaviest, and the level of comfort you get in a fairly compact, lightweight is worth it in my opinion.

        Sleep System = Good Sleep

          When paired with the Big Agnes bag this sleeping pad is amazing!!!! Do yourself a favor and get them together. I tend to roll around in my sleep a lot. With a typical sleeping bag on top of a pad I end up in a knot off the side of the pad. Not with this system. With the sleeping pad in the sleeve under the sleeping bag I am able to roll around all night long, like I would in my bed at home without getting tied into a knot or ending up off the side of the pad. It also keeps you super warm. Just make sure you get the right pad for for the bag you are looking at.

          Love Big Agnes Pads

          • Familiarity: I've put it through the wringer

          These pads are the best. They are well-made, compact and light weight. They are very comfortable. We especially like the fatter baffles along the outer sides. This design feature serves to "cradle" us in the pad... no more slipping and sliding off during the night! Highly recommended and worth the price.

          Finally, a tent mattress I can sleep on.

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

          I hike 100+ days per year, but I have backpacked only about 25 days because I always have trouble sleeping in my tent. Makes hiking less enjoyable after one or two sleepless nights. I have tried sleeping on inexpensive foam pad and highly-rated Big Agnes Q-Core mattress...without success. I even put the foam pad and Q-Core together a couple of times, but still no luck.

          Finally, in Big Agnes Q-Core SLX, I found a mattress I can sleep on in my tent. I used it two consecutive nights on a three-day backpack over Thanksgiving holiday, and I slept better than I ever remember while camping. Q-Core SLX is lighter and more compact...and inflates much quicker...than my original Q-Core, and for some reason it is quieter when I turn from side to side. I was even able to sleep some on my back on the SLX...a first! I'm not thrilled with the lime green color, but I love the fact that SLX has two openings: one for inflating (which retains air in between breaths) and one for deflating.

          Because I spent the money on it, I'll try the original Q-Core again when car camping. But Q-Core SLX is now my go-to backpacking mattress.

          Sleep like a baby

          • Familiarity: I've put it through the wringer

          Without question the best sleeping pad I have owned. Over the last 35 years I have tried tons of different sleeping pads, but none have compared to the Q-core SLX. We bought them specifically for thru-hiking the John Muir Trail in July of 2017 and found them to be easy to set up (with the stuff sack of course), lightweight, durable and nice small pack size. Well worth the money.

          Highly recommend this product

          Sleep like a baby

          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.
