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.

Great product with minor design flaws
Reviewed by Everette G. - October 17, 2018

Likes: Super comfortable, keeps you several inches off the ground, Big Agnes finally fixed their valves, super warm, soft and quiet, didn't hold condensation, distributes weight great, keeps you off the ground when laying on your side, stuff sacks are good quality, held up great to 3 very happy camping dogs and their paws

Dislikes: Definitely need the pumphouse to blow up, requires a massive amount of air, the regular width is pretty narrow, your arms will fall off the sides, repair kits are just loose in the stuff sacks, wish there was a more grippy surface on the bottom

Like New Valve Design of Big Agnes Q-Core SLX Pad
Reviewed by Mike B. - October 17, 2018

Likes: Purchased this pad to replace my older Insulated Q-Core SL. Really like the new valve design. It's easy to inflate and equally easy to de-flate. Would definitely recommend purchasing the Pumphouse bag, which cuts down on moisture in the pad and running out of breath.

Dislikes: None so far.

light weight
Reviewed by Christie S. - October 8, 2018

Likes: For the price, weight, comfort and R value its a great compromise to the thermarest neoair. Really like the side rails, helps keep you center.

Dislikes: take quite a bit of effort to blow up.

Long works well.
Reviewed by Darshan G. - September 4, 2018

Likes: I opted for the long size and it worked well for me. Packs small, easy to inflate, and definitely thick enough for a side sleeper like me.

Dislikes: Consider buying the bag house because inflating may be a chore at the end.

Great pad for the money and comfort
Reviewed by Ed S. - August 18, 2018

Likes: Like the higher outside edges of the pad to keep from sliding off side to side.
Easy to inflate and deflate.

Dislikes: n/a

Lighter and thicker than ultralight therm-a-rest
Reviewed by Kirsten I. - August 16, 2018

Likes: Got this because my partner has a similar (albeit older) pad. I thought i'd keep my ultralight thermarest because I assumed this would be heavier / bulkier. Turns out it's neither of those things! Very comfortable for this side-sleeper. Would (and have) definitely recommend.

Dislikes: None so far! But I've used it only 2 consecutive weekends.

Comfy and well insulated
Reviewed by Greg - August 12, 2018

Likes: 1.5” thicker than my 2.5” air core big agnes I use to carry. It is also much lighter as well. Definitely better insulated too.

So nice I bought 2 more to replace 3 big agnes air core I’ve had for years.

I bought the big agnes pump bag for it and makes inflating much easier.

Dislikes: Does make more noise than my big agnes air core, but hasn’t woke anyone up from it.

very comforatable pad that packs small
Reviewed by Christopher S. - August 8, 2018

Likes: very comfortable easy to inflate with pumphouse bag. slightly thicker outer baffles make it a really stable sleeping pad. pretty quiet .

Dislikes: none

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.
