    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 along the inner air chambers to ensure your shiny new mat doesn't become a smelly, moldy mess over time.

    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

    Don't skimp on comfort

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

    I have used this pad for backpacking and bikepacking. It is by far the most comfortable sleeping pad I have used. Previously I had been using a foam Thermarest pad which was great for using and abusing. I like not having to worry about popping it but it wasn't very comfortable. I also had a inflatable Thermarest which was comfortable but didn't pack down small. This pad strikes a good balance between what I look for in a sleeping pad. Primary concern is comfort- with it's quilted design it is very comfortable whether you sleep on your side, stomach of back. The inflate valve has a slick feature to fine tune the insulation of the pad so as to make sure it's not too firm or too soft. Second most important feature for me is packability. This thing packs down pretty small, definitely not the smallest on the market but good enough for me. About the size of 1 L Nalgene water bottle . My third focus is durability. I have been pretty gentle with the pad so far, making sure I am not setting it up on anything sharp that might pop it. Only time will tell but the thin light weight material has me concerned about even a pine needle popping it.

    I am 6'5" tall and the regular size 20"x72" pad is enough for me.

    What a difference

    • Familiarity: I've used it several times

    I ditched my 17 year old Therma Rest slightly inflatable pad for the Big Agnes. Wow. It is like night and day. Super comfortable and great insulation. At 42 degrees I was warm enough in my tent to sleep in a long sleeve base layer and no cap or gloves. The condensation under the tent where the pad was was non-existent. Where the pad was not was wet as could be. The pad really makes a difference. Just as nice, it is easy to inflate and stow. About 2 minutes to blow up and rolls up nice and compact.

    Packable and Comfortable

    • Familiarity: I've used it several times

    This pad is great and I would expect nothing less from an Item coming from Big Agnes. I have the long and am amazed at how small this pad gets and how light it it, especially given the thickness of the pad. The valve makes this pad the easiest to inflate out of all the sleeping pads I have owned.

    I like em thick!

    • Familiarity: I've put it through the wringer

    The Big Agnes Q-Core weighs in at a pound but somehow manages to provide over 4 inches of thickness. I am a side sleeper, so the thicker the better. I use this pad and the Big Agnes Fish Hawk sleeping bag whenever I go backpacking and I've never been more comfortable. The insulation of this pad, partnered with my 30 degree bag, keeps me warm at temps below 30 degrees.

    It is a bit slow to blow this pad up, but that's to be expected when using such a thick, comfortable pad. Another cool feature Big Agnes integrated into this pad are the two air valves - one for air flowing in and one for air flowing out. When you want to blow up your pad, you just pop the "in" valve and start having at it, but no air can get out while the "out" valve is down, which allows you to take your time and not get dizzy.

    Sleeping on the couch tonight

    • Familiarity: I've used it several times

    You heard me, I'm sleeping on the couch tonight, or should I say, Q-Core SLX Sleeping pad!

    This pad is plush stuff - made out of durable materials, it will hold up if your 80lbs pupper starts stomping around on it. The open/close tabs are as simple as they come, no issues with deflation. No noise when moving around, this pad is a dream come true.

    Lastly - look at the price, can't beat it for a QUALITY pad. Packs up decently, little larger than my STS pillow. goodbye sleeping on blankets, hello 8 hrs of sound sleepy time.

    Awesome pad for warmer temps

    • Familiarity: I've used it several times

    I love the size and thickness of this pad (I have the long as I'm 6'6") Pad is exceptionally thick (4") and provides the best comfort I've found for me. I'm a side sleeper and I often experience a lot of hip pain when sleeping in the backcountry.
    My only complaints are weight and temp rating. I weighed mine and it came in at 20 oz. 3 oz heavier than the advertized weight of 17oz. I used the pad with my Big Agnes Blackburn UL 0deg bag all spring during bear hunts. Temps hit low of 28 and I could defiantly feel the cold ground through the pad using a XPG bivy sack. The pad is rated to 15deg so that's a little bothersome given I was nearly double the temp rating. I still love the pad considering it's size and weight it's still a bargain but not a 5 star bargain. It irritates me that the actual weight isn't really close to the advertised weight.

    Hit Snooze

    • Familiarity: I've put it through the wringer

    I hate to admit it, but I've been camping for years and never can sleep through the night because I'm a stomach sleeper, and my arms always go numb during the night due to inadequate pads. My life is now changed. The first night on the Q-Core was legitimately the first full nights sleep that I've gotten camping, and I'm not even exaggerating.

    It gets better. The Q-Core is light, easy to blow up, and barely takes up any room in my pack. It doesn't make an annoying amount of noise, either. The first night I used it the temperature was about 30 degrees, and this pad provided great insulation from the ground. If you're looking for great sleep, ease of use, and a pad that doesn't take up your entire pack, I highly recommend the Q-Core.

    This pad is EVERYTHING.

    • Familiarity: I've used it several times

    It's super comfortable, like possibly better than my bed. After night one my partner was immediately jealous and ordered one for himself. I did not find it noisy.

    I have the petite (66" length) and at 5'5" height it's perfect for me, plus I have space left in the tent to keep my backpack at my feet. The ~4" depth keeps you blissfully unaware of any rocks or roots under you, plus I imagine if it pours and your tent floods you'll stay good and dry--you'll just want to make sure you orient yourself so you're not sleeping on a L-R slant or you'll feel prone to sliding sideways. The 20" width is a bit spare for sleeping with a doggie in your bag, but it does fit perfectly in the Big Agnes sleeping bag pad sleeve (I have the Haybro).

    Speaking of doggos, after 3 nights of two hyperactive spazzes trampling it, no punctures. The BEST thing is getting the Big Agnes Pumphouse Ultra--this allowed me to pump up two pads easily even with a dislocated finger. It takes about 6-7 pumps/4-5 min to inflate one pad, saves your lungs, and keeps moisture out to prolong the pad's longevity and prevent mold. No leakage all night long, the in-valve doesn't seep while inflating, and the out-valve deflates instantly.

    Packs up really small and fits anywhere in your pack. Lightweight. I cannot think of a single con to mention. Will see if it holds up once I've put it through the wringer.

    Q- Core SLX Sleeping Pads

    The Q-Core SLX ups the ante on quilted comfort in the backcountry. Redesigned offset I-Beams create incredible multi-directional support and stability. The Q-Core SLX is lighter, tougher, easier to inflate/deflate, packs smaller, sleeps warmer... when it comes to superlight, 3-season comfort this pad stands alone.

    Initial Impressions

    • Familiarity: I've used it several times

    I picked up the Q Core SLX for two reasons:
    1. To compare the comfort of the offset Ibeam construction vs the vertical Ibeam construction on the Exped Synmat UL7 since it's the same weight.
    2. Test the new valve system, which has to be better than BAs previous valves which weren't that great.

    Initial impressions: I do think the Q-Core SLX's design is more comfortable and I don't slip of the pad like I did on the Synmat UL7. I find the valve system to be kind of funky to inflate, but adjusting pressure and deflating is easier than any other system out there. It's not as light as the NeoAir Xlite or Synmat Hyperlite, but the extra comfort is worth the 4 oz in my opinion.

    Will test durability over the upcoming backpacking season, but I'm pretty impressed after a few uses. Will update!

    Easy to use and comfortable

    • Familiarity: I've used it several times

    This is my second Big Agnes sleeping pad, and I've had nothing but good experiences. (Unfortunately the first one met a terrible end when I loaned it out to a friend.)

    I'm always amazed at how quiet these sleeping pads are without sacrificing weight. It won't be as quiet as your old closed cell foam pad, but it's definitely quieter than any other air pad I've tried.

    The new valves are awesome - you don't accidentally deflate the pad when you're trying to add more air. It's super nice to be able to fine tune the amount of air quickly and easily.

    So comfortable!

    • Familiarity: I've used it several times

    I am a side sleeper and always have a hard time sleeping on a mat that provides enough support for my shoulders and hips. This mat has been amazing! I have slept several nights on it very comfortably, with absolutely no pain or tossing and turning! Also, the valve system is brilliant - the air won't come out as you blow it up, and the release valve is large so it deflates very fast! It also rolls up very small and is lightweight. I will be taking this mat everywhere!

    New and Improved

    • Familiarity: I've put it through the wringer

    I started using the Q-Core pads when they had the corner mounted valves that were prone to failure as noted in a previous review. This new design seems to have addressed the pointy corners that were causing the leaks. Besides those leaks these are great pads, weighing in at almost nothing and having about the same overall volume as a Nalgene bottle when deflated. In my opinion these are a better all around 3 season pad than any other available right now.

    The attached picture is a petite model for my wife, but the larger pads aren't much larger when rolled up.

    Poor reliability

    • Familiarity: I've used it several times

    *it looks like Big Agnes has updated their valve system from the one I am reviewing, so take my review with a grain of salt

    I've had two of these (first one warrantied, about to warranty the second one). First one had a poorly welded seam near the foot that started leaking the second day I slept on it. Not great on a 45 day trip. Couldn't warranty immediately, but was able to repair, until the area around the valve started leaking. Warrantied that one, but now am having the same air leaks around the corners of the valve on my warrantied pad, after sleeping on it maybe 30-40 days. I've repaired it, but is still losing air, and is a tough place to patch. I'm going to return it again, and ask for a refund unless they can guarantee that the same area will not start leaking on a third pad.

    Great Sleeping Pad

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

    My mom got sick of me using her sleeping pads, so she got this for me as a gift. So far, I love it! The bright color will make sure you never lose it and despite the rough ground it has protected me from, I haven't had any leaks. It's incredibly easy to inflate and doesn't take long (even though the pad is 4") and I LOVE the quick deflate functionality. This pad is incredibly light and packs down nice and small. My only complaint is that it is a bit louder than I would have liked, but it is far from the loudest sleeping pad I have ever used. I have only used this in warm climates, so I can't speak to its warmth.

    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.
