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.

Frikkin Awesome
Reviewed by Jason B. - January 9, 2018

Likes: It is very very comfortable! Love the ability to deflate for comfort level. I’m 5’10” and have broad shoulders and sleep in my stomach. This pad is perfect for me.

Dislikes: No dislikes.

Nice sleeping pad
Reviewed by Alayne S. - December 3, 2017

Likes: light weight
doesn't take up much space in pack

Dislikes: takes quite a few breaths to inflate

Comfy and small
Reviewed by Michelle C. - October 10, 2017

Likes: Got the petite to save on space, weight and price. I'm a side-sleeper anyway so my knees curl up. Can't attest to warmth because I used this in Florida. We just don't do cold here. Hits the mark on all the above though and it's comfortable. And I got it on sale. I'm literally a happy camper.

Dislikes: none

Bed anywhere
Reviewed by Peter M. - July 6, 2017

Likes: I had the orange q-core (previous model) which I've spent countless nights on, and just upgraded to this (with the pumphouse). The design improvements in this model are fantastic- valve is great, super easy and quick deflation.. and of course- the most important thing- I think this is the most comfortable lightweight air mattress on the market. I get the same quality of sleep on this as I do on my bed at home.

Dislikes: I liked the orange color of the previous version more

Q-CORE SLX Sleeping Pad
Reviewed by Al S. - July 3, 2017

Likes: * Compact compared to foam pads.
* Inflates quickly with the BA Pumphouse Ultra (additional purchase).
* Deflates quickly when you are ready pack up and move out.
* Bought the Wide Long pad which works well for me ( 6"3" , 200 lbs.).

Dislikes: None so far.

An awesome sleeping pad
Reviewed by Marcus O. - June 26, 2017

Likes: I was really impressed with this pad. I went for the long wide version which fits inside my Copper Spur UL1 no problems. The pad is supercomfy with a nice sleeping surface that feels like the mattress at home. It is durable as well for the weight. Lots of loft for side sleepers and a great pad all around.

Dislikes: Inflation time is around 25 breaths. You can always go for the Big Agnes Pumphouse Ultra.

Comfortable but cool
Reviewed by SH - April 12, 2017

Likes: As a tall side sleeper I purchased the long wide version and for its size it's pretty light weight, 24.5 Oz with the stuff sack. I slept on this pad about 10 nights last fall. This is definitely the most comfortable pad I've slept on. It's also quiet unlike my friends NeoAir Xlite. I was skeptical of the new valve system at first, but it works very well. It deflates much faster than any other pad I've used and the one way valve makes inflating easy. The pad seems pretty durable, it survived a bear tearing my tent up and dragging it off into the trees. (My fault, left a granola bar in the tent)

Dislikes: I only got to try this pad out on snow for one night before the bear wrecked my tent. It was not warm at all compared to my old self inflating pads. I'm guessing the NeoAir XTherm MAX would be a better choice in the cold. The long wide pad is big and as such requires a lot of air to inflate. I'll be purchasing a Pumphouse Ultra to help speed up inflation.

Big Agnes Q-Core SLX
Reviewed by NJBOnTheAT - March 27, 2017

Likes: - Very comfortable and ultra-light
- Packs small

Dislikes: I would be leary of using this in cold temperatures with the Big Agnes sleep system bags; I used it recently on a trip where the temperatures dipped into the mid 40s and it had cold spots; I expected it to hold my body heat a little better than it did. Still a great pad however given its size and weight.

Comfy Pad!
Reviewed by Adam - November 30, 2016

Likes: Very comfortable and spacious pad! The quilted design provides a very even sleeping surface. I ordered the regular/wide as I am a side sleeper and love the extra room. I also tend to move around a lot and the pad is very quiet. LOVE the separate deflate valve & it is super quick to deflate. I highly recommend purchasing the BA Pumphouse Ultra to use to inflate the pad. Very easy to attach and saves time blowing up and also will increase the life and elimate mold build up on the inside.

Dislikes: A little "bouncy" as it is a thick pad and has a lot of air. Pumphouse should be included with the pad and a standard to use it to inflate. Not a 4-season pad.

Fantastic Sleeping Pad
Reviewed by Jamie B. - October 10, 2016

Likes: I've used self inflating sleeping pads, lightweight pads, etc. over the years but this is hands down the best backpacking sleeping pad I've ever used. I'm a side sleeper and it's tough, for me at least, to find a pad that's lightweight and comfortable. I was using a NeoAir but I kept getting woken up by my hand on the side I was sleeping on falling asleep. I don't have that problem with this pad. I used it for the first time on a recent weekend backpacking trip and got the best night's sleep I've ever had on a backpacking trip. It's a little heavier than my lightweight pad but well worth the extra 4 oz. for the comfort. It also didn't seem to slip around on my cuben fiber tent floor like some of the other pads. I forgot to put some double sided tape on it for grip like I have on my other pads but even without the tape the pad didn't slide.
