  • Synthetic Insulation For Warmth With Minimal Bulk
  • Nylon Fabric Improves Tear Strength And Durability
  • High Volume Valve For Fast Inflation/Deflation
  • Antimicrobial Treatment Prevents Microorganism Growth (AKA mold)


The Big Agnes Insulated Q-Core SLX is an inflatable sleeping pad that comes in at a very reasonable price point. While we found that the Big Agnes Insulated Q-Core SLX doesn’t do anything exceptionally well, we did find it to be a very good middle-of-the-road sleeping pad. 

What we like most about this pad is that the (Long Wide) version works very well for big and tall sleepers. We like that the included pump sack is upcycled. We like how the baffles on the outer edges hold you in the center of the pad creating a stable night’s sleep. The material is soft to the touch and not too noisy. 

What we don’t care for is the valve system. The valve seems a little outdated and the pump sack detaches from the valve too easily. Although we like that the pump sack is upcycled, we don’t actually think this pump sack is very functional. It takes a long time to inflate the pad and just overall doesn’t seem to work as well as other pump sacks that we’ve tested. It’s also quite heavy for a pump sack. 

Therm-A-Rest NeoAir Xlite

If you’re counting every single ounce that goes into your pack, this is the sleeping pad for you. The NeoAir XLite from Therm-a-Rest is lightweight, easily packable, and will help you rest easy at the end of a long day. The pad includes a reflective layer that returns valuable heat to your body and creates air pockets that help you conserve additional warmth. This pad is made with softer fabrics to make it more comfortable on your skin and also helps improve the durability of this pad. The tapered design helps to reduce the overall weight of this pad while also making it less bulky when you store it away in your pack during the day.

The pad boasts a total of three layers of metallized reflective film to improve heat retention and keep you warm during cold-weather camping adventures. The pad’s micro-adjustable, multifunctional, zero-profile air valve makes it easy to inflate and deflate while the included pump sack helps you save your breath. It also helps to minimize any buildup of moisture that can occur inside sleeping pads when you blow them up with your mouth.

With an R-value of 5.0, the Sea to Summit Comfort Plus Insulated pad is a mountaineer’s dream on a cold night. The pad combines platinum fabric with synthetic insulation to prevent both radiant and convective heat loss. It boasts a two-layer design that allows each layer to be inflated independently of the other. This allows the pad to retain cushion if one of the layers is punctured. It also allows you to inflate the bottom layer more for protection against hard terrain and the top layer less for a soft, comfortable sleeping surface. This sleeping pad also has a pump integrated into the stuff sack to make inflation much easier.

View Women's Version
  • Insulated: Yes
  • Thickness: 4”
  • Pad Type: Air Pad
  • Pad Shape: Semi-rectangular
  • Dimensions (Regular): 72 x 21.5 x 4 inches

  • Metallized Layer Minimizes Radiant Heat Loss, Keeping You Warmer
  • Lightweight Fabric For Easy Field Repairs
Sea To Summit Ether Light XT


The Ether Light XT from Sea to Summit will keep you out and about when the rest of your friends have run for the comfort of home. It delivers greater thickness with lower overall weight through a “spring-and-loop” construction style that creates the feel of a pocket-sprung mattress. This makes the pad supremely comfortable and supportive while a metallized layer works to reflect heat back to the body and minimize radiant heat loss. Because the pad is made from lightweight fabrics, you’ll also be able to easily repair it in the field if a puncture or scrape does occur.




Pads that use closed-cell foam are relatively inexpensive and tend to last. They’re also lightweight and provide decent insulation against the cold. Perhaps the largest benefit of this type of sleeping pad is that you don’t have to worry about punctures or leaks. You’ll be able to carry this pad on the outside of your pack without worrying about it scraping against a tree or rock. And you’ll also be able to use it as a sit pad when you’re hanging around camp. The downfall of this type of sleeping pad is that they don’t provide a lot of support or cushion. In other words, they aren’t as comfortable as some of their counterparts. 

Air pads are either self-inflating or require manual inflation by the user. Self-inflating pads are generally more expensive than closed-cell foam pads and aren’t quite as compact as manual-inflating air pads. They meet a nice middle ground between the two, however, and can be a great choice for the kids. 

Manually-inflating air pads are the top-of-the-line options in terms of comfort and insulation when mountaineering. They’re also lightweight and most pack down to a relatively small size when not in use. They also allow you to customize the firmness of your mattress by adding or removing air to your liking. The downsides of this type of sleeping pad include higher price, greater likelihood of tears or punctures, and a bothersome tendency to feel like they’re losing air. It’s best to blow up this type of mattress right before you go to sleep, as fluctuating external temperatures can sometimes be the cause of these pads feeling as if they’re not providing as much cushion as you’d like. 



Now that you understand a little more about the different types of sleeping pads, it’s time to dive into your intended activity. Are you going to be hiking the full length of the Pacific Crest or Appalachian Trail? Do you need a pad that will keep you comfortable sleeping in high alpine environments? Or do you just need a pad that you can throw down in the back of your car for the night? 

There is a lot of variety in the ways people use their sleeping pads and, as a result, there are sleeping pads made for almost any intended activity. While the breakdown we’re about to offer is generalized, we hope it will give you a good metric to start from. 

If your intended activity is car camping, you’ll probably be most happy with a self-inflating pad or a thick air pad. This will give you more cushion and you won’t really be worried about a larger pad taking up too much space. 

If you’re heading out for a few days on a backpacking, kayak camping, or bike packing trip, consider a self-inflating pad or a lightweight air pad. These will be easier to fit into your setup and provide plenty of comfort overnight. 

Minimalist backpacker and thru-hikers should choose from ultralight air pads or closed-cell foam pads. You don’t want to carry a bunch of extra weight or be trying to stuff a large pad into a small backpack. 

Finally, if winter camping is your thing, certainly do more studying into R-values and look at thicker air pads or self-inflating pads that have more insulation. Synthetic fibers and down are two of the best insulation materials used in winter camping sleeping pads. 



A sleeping pad’s R-value denotes how well it resists heat flow. In other words, a higher R-value means the pad is designed to keep you warmer and more insulated from the cold ground. While it’s not always necessary to get a sleeping pad with a high R-value, especially if you do most of your mountaineering in the summer, keep in mind that a higher R-value typically translates to a warmer you! 

There are, however, different types of insulation used in sleeping pads as well. Synthetic insulation is commonly used in air pads to reduce heat loss to the ground. Four-season sleeping pads may use down insulation to further reduce this heat loss.  

There is no magic formula for determining the “right” R-value for you, but most mountaineers will prefer a pad with an R-value of at least 3, even during the summer months. If you always tend to sleep cold, think about opting for a sleeping pad with an R-value of 4 or higher. And if you’re going to be mountaineering in extreme cold weather, look for pads with an R-value of 5 or higher. 



The dimensions of your sleeping pad come into play as soon as you lie down. If you’re taller, you’ll want a longer pad. If you’re wider, you’ll want a wider pad. We know that’s not rocket science, but keep this in mind: the more of your body that hangs off the ends of edges of your sleeping pad, the more opportunities for heat loss. Thankfully, most sleeping pad manufacturers offer their pads in long and wide sizes so that you can find the right model that fits you. 

When it comes to weight, this factor largely plays into how much you want to carry on your intended activity. As we mentioned above, car campers probably don’t need to worry too much about the weight of their sleeping pad. Multi-day bike packers and kayak campers don’t have to carry that weight directly on their backs either. 

But if you are undertaking a long and arduous mountaineering trip, every ounce begins to matter the further you progress on your journey. Pads with a mummy or tapered shape will help you save weight while still enjoying the necessary features that will help you sleep comfortably. 



The inflation system, or air valves, on a sleeping pad can wind up causing problems if they’re not designed well. This is the primary area where air flows into and out of the pad. So if it doesn’t allow air to flow well enough, it’ll take way too much effort to inflate your pad. Conversely, if it doesn’t create a tight seal, you’ll find yourself sleeping on hard ground when you wake up in the middle of the night. 

Two-way, self-sealing valves are designed to eliminate both of these unfortunate circumstances. They don’t let air in until you provide enough air pressure, which is usually best done with a hand pump or pump sack. They also don’t let air out until you’ve manipulated them precisely to do so. When it comes to inflating sleeping pads, these valves go a long way to keeping your pad inflated and keeping you comfortable. 

There’s one more thing that should be mentioned about inflating air pads. If you’re using your own breath to inflate them, this increases the likelihood that moisture can get trapped inside. In cold temperatures, this can lead to freezing issues and in warm temperatures we start worrying about mold growth. When in doubt, get a hand pump or pump sack to inflate your pad. Better yet, buy a pad that already has one of those pumps integrated in its design! 





R-value is a measurement that refers to a material’s ability to resist heat transfer. A higher R-value means greater resistance and a lower R-value means less. In terms of sleeping pads, a higher R-value means less heat transfer away from your body (i.e. greater heat retention to keep you warmer). 


Baffles help to control air flow within an inflatable sleeping pad. When they’re doing their job properly, they work to keep cold air near the ground and the warm air from your body closer to your body. 


This is where air is let into, and out of, your sleeping pad. It is also one of the primary culprits when a sleeping pad doesn’t retain air. The design and construction of the air valves plays a major role in the performance of mountaineering sleeping pads. 


This is a term that refers to the thickness of individual fibers used to create fabric. Fabrics with higher denier count tend to be thicker, sturdier, and more durable. A lower denier count means a fabric is softer and silkier. 


Relevant only to air pads, this term refers to the pockets of air created inside the pad when it is inflated. The design of these chambers plays a large role in how well the pad retains air, cushions your body, and retains warmth. 


A pump sack looks like a large stuff sack (you know, the thing that you stuff your sleeping bag into). Except these have a vinyl gasket on the bottom and they attach to your pad. By pulling the sack outwards you fill it with air. Then, when you compress the sack, the air is pushed into the pad. This is a much easier and efficient way to inflate air sleeping pads.
