Utilizing a unique "quilted" design, the compact and ultra-lightweight Big Agnes Q-Core SLX inflatable sleeping pad combines warmth and comfort for 3-season backpacking. An internal layer of synthetic insulation bolsters the pad’s thermal efficiency.

The pad’s nylon rip-stop top and bottom have internal polyurethane coatings for waterproof protection. The alternating I-beam construction provides a smooth, comfortable feel and a full 3.5" of thickness. Dual high-volume technology allows for easy one-way inflation and convenient, super-fast deflation. Larger outer baffles help to keep you comfortably on the pad throughout the night. An internal antimicrobial treatment extends the life of the pad. Big Agnes has rated the pad for use in temperatures as low as 15 degrees Fahrenheit.

The Big Agnes Q-Core SLX inflatable sleeping pad is available in a wide array of size options. A stuff sack and repair kit are included with each pad. NOTE: Always store the pad unrolled with the valve open.

Sleeping on Clouds
Reviewed by Cody R. - July 9, 2018

Likes: Most comfortable pad I ever used. Way better than the thermarest neoairs.

Dislikes: I wish there was a 30 inch option..

Somewhat comfortable, takes a whole lot of breath.
Reviewed by Tulam L. - May 31, 2018

Likes: A little higher off the ground, decent insulation, compact and easy to pack up.
I'm 5'2 and a little on the heavier side, the petite fit me just fine, I just wish it was a tad bit wider.

Dislikes: A little too narrow, when you sleep on a hill you're constantly sliding during the night.

Very Comfortable
Reviewed by Bill B. - May 13, 2018

Likes: This pad is lightweight and easy to pack. It is very comfortable to sleep on after a long day of hiking. The r factor is great. Would highly recommend it. I've had mine for 2 years now and have had no problems with it.

Dislikes: Loses a little air throughout the night. Takes some time to blowup, would recommend using the Big Agnes bag pump to blow it up. Pump should be included with it.

Comfort at last
Reviewed by Lisa K. - May 8, 2018

Likes: I love the quilted design of this pad. I've had trouble sleeping on every other backpacking mattress I've purchased until now. Neither horizontal or vertical baffles are comfortable for me, but this design works. I like that it's designed with a little extra height at the sides to keep you on the pad. I really appreciate that it comes in a variety of lengths and widths so that you can purchase just the size you need. I need a wide pad, but I'm short. They have a pad for me! While not as light as the Thermarest Neoair I was using, it's still quite lightweight, and a great pad for the price. I'll happily carry a few extra ounces if it means finally getting some quality sleep in the backcountry.

Dislikes: I wish the pad material had a little more of a fabric feel. A heavier version of this pad exists that does. I tried that pad in an outdoor store, and hoped this one would feel similar. It's just a little more slippery than I would like. The only other dislike I have is that you have to buy a pump sack separately, and they're selling for $35. Since it's a proprietary nozzle, I feel that they should include it with the pad, even if the price went up a bit. I didn't have the pump sack on my first trip out with it, and it was difficult inflating it with the sack that I had.

Likes: Small, lightweight, comfortable, easy to fit into included bag.
Had the opportunity to compare this one to the Big Agnes AXL Air sleeping pad, and was very surprised how much more comfortable the Q-Core SLX is. I'm happy with my purchase!

Dislikes: For the price it would have been nice for big Agnes to include the pumphouse ultra.

great for a tall, side sleeper
Reviewed by lloyd - May 4, 2018

Likes: firm, comfortable, and slept easily. i got the wide-long, as i move a lot in the night and felt like i'd be constrained or fall off the regular width. really liked the thickness, which kept me from feeling the ground, and felt more like a firm mattress. the pumphouse ultra made inflation easy.

Dislikes: disappointed the pumphouse ultra is a separate purchase. other brands use the provided stuff sack for inflation.

a good sleep!
Reviewed by Tom - May 3, 2018

Likes: deflates quickly, doesn't take up much room. no extra 'squeaky' noise when moving in my sleep.

Dislikes: takes a few breaths to blow up.

Super lite pad
Reviewed by Inside Edge Member - May 1, 2018

Likes: I purchased for my Yampa 45 and couldn't be happier. It's very comfortable and the adjustable valve is a nice convenience.

Dislikes: None

Cadi Comfort
Reviewed by Dean C. - February 6, 2018

Likes: Nice thick air pad with a comfortable sleeping top.

Dislikes: 6-7 ounces heavier than my long / 25 inch wide Neo Air. The rectangular shape did not allow enough space at the foot end of a tapered two person tent (with two people).

Great Pad
Reviewed by Marsha C. - February 4, 2018

Likes: I purchased a sea to summit comfort light which was 2.5 inches thick and had great reviews. to me it was way to thin as a side sleeper and sould feel the ground when turning over. Bought this Q Core SLX pad. Best purchase I have ever made. I am 6'7 208 pounds. I purchased the Large Wide size. It is perfect. I recommend purchasing the Big Agnes pumpsack to inflate it as it is very easy to do so compared using your breath and getting dizzy. Very comfortable pad. I have not used it yet outdoors so i cannot rate the insulation. regardless I am loving this pad. Light weight, packs small.

Dislikes: Nothing.
