Klymit Vs Thermarest Sleeping Pads

In this article, we're looking at two of the biggest names in outdoor gear that specialize in sleeping pads: Therm-a-rest and Klymit. We'll provide an in-depth look at both brands, unearth what makes them special, and see if their sleeping pads really are as good as they say they are. 

First of all, why do you need a sleeping pad, anyway?

If you've ever been camping and slept without a mat then it's likely you know the answer to that question already. Waking up with a stiff neck or bruised hips isn't a great way for anyone to start their day. Whether you're an expert mountaineer, a seasoned hiker, or a casual camper; a good sleeping pad can make a huge difference to your sleep quality.

Did you know that the ground conducts heat 60x faster than air? A huge amount of body heat is lost to the ground or tent floor. Sleeping pads prevent heat loss to ensure you stay warm and cozy throughout the night. When it comes to choosing a good tent, there are plenty of things to consider. 

The best sleeping pads are comfortable, lightweight, and provide support where you need it most. Whether you're sleeping on the grass, snow, or rocky ground; a thick and protective mat is the key to a good night's sleep. You might not know it, but a good sleeping pad is every bit as essential as a sleeping bag. 

If you're an outdoors enthusiast, or you've paid attention while walking around your local outdoor sports store, then you've probably heard of Therm-a-Rest and Klymit before. Both brands are big players in the outdoor gear industry, but today we're here to settle the great Klymit vs Therm-a-rest debate! 

We've got a lot to cover, so let's dive right in. 

Thermarest VS Klymit Sleeping Pads

They're both big names when it comes to quality outdoor gear, but how do Therm-a-Rest and Klymit sleeping pads stack up against each other? Let's find out.

Therm-a-Rest was one of the first companies to build inflatable sleeping pads, as their founder seized the opportunity to create a mattress that offered greater comfort than the closed-cell foam mats popular in the 1970s. Nowadays, Therm-a-Rest provides all kinds of products for outdoor enthusiasts to make a night in the woods more enjoyable. It's one of the best brands all-round for quality gear that delivers on comfort and warmth. Therm-a-Rest produces sleeping pads for any kind of activity.

The Klymit Static V2 is consistently mentioned as one of the top sleeping pads in outdoor gear reviews. It's super lightweight and can be packed down nicely into a stuff sack, making it ideal for ultralight backpacking. However, it has a low R-value, so it's only really ideal for summer camping and backpacking trips where the temperatures don't drop too low. That said, they make several insulated sleeping pad versions of this model, including the Insulated Static V Lite (see below for more on this model). 

This model is built with thicker material than your usual lightweight air pad and is slightly wider than the standard size.

Buyer's Guide to Sleeping Pads

Type of Sleeping Pad

Different types of sleeping pad products are better suited to different situations. Here's an overview of the 3 main categories of sleeping mats, their key features, and the situations they're most practical for.

Closed-cell Foam Pads

These are the most basic kinds of sleeping pads. They feature small closed air cells that provide moderate comfort without fully inflating. They don't offer much in the way of insulation, but they're extremely lightweight, durable, and cheap. They can be uncomfortable, and they're usually not very compact.

Good choice for people on a budget, overnight trips, summer camping, or ultralight backpacking.

Air Pads

These rely on air for inflation. They can be inflated manually or by using a pump sack. Thicker than closed-cell foam mats, they usually provide ample comfort for getting a good night's sleep. They're also light in weight and usually pack into a compact stuff sack for easy carrying. These can be noisy if you move around a lot when you sleep, and pumping them up can use a lot of energy after a long day in the outdoors.

Air pads are a good choice for All kinds of outdoor activities, backpacking, and hiking as they come in a variety of styles.

Self-inflating Pads 

These are the preferred choice of many campers. Just unfold them and they'll inflate by themselves. They feature open-cell foam for excellent insulation and comfort. Self-inflating mats are durable, compact, and provide excellent insulation, making them a good option for general camping, hiking, and backpacking. However, they can take some time to deflate and can be quite expensive.

Self-inflating pads are a good choice for backpacking and car camping.


When choosing the right sleeping pad to suit your needs, you'll need to consider what function you need it to perform. Think about what activity you're planning. For example, if you're going on a summer camping trip with friends a regular air pad mattress might be just what you need, whereas you'll probably want an ultralight self-inflating model if you're embarking on a long hike in the wilderness.

You'll always need to consider the climate you're going to be sleeping in, as a good sleeping pad can make a huge difference to your sleep quality in colder conditions. 

If you're car camping, and not limited by size or weight, you can opt for a thicker self-inflating air pad or even an air mattress. Air mattresses allow you to use regular sheets and blankets rather than sleeping bags, for a more home-style camping experience.

Seasoned hikers will need to consider sleeping pad options that are lightweight and have a small packed size. Closed-cell foam mats offer more durability than inflatable options and come in short of 3/4 length sizes to save on weight. 

If you're backpacking you'll need to consider a lightweight option to save you from carrying around a lot of extra weight every day. The best backpacking sleeping pads offer supreme comfort and have a relatively small packed size. 

If you're embarking on a Winter camping adventure, then an insulated sleeping pad with a high R-value is crucial to staying warm during the night.

When it comes to selecting the best sleeping pad, you'll need to assess your own situation and what you need from a sleeping pad. Think about:

  • Where you're going
  • What the temperature will be like
  • Your sleeping preferences


This is an extremely important consideration when choosing the right sleeping pad to suit your needs. Practicality and portability can make a huge difference.

Once you've packed the essentials like your trekking poles, your waterproof hiking pants, and food for the day; it's likely that your bag will be pretty heavy. You'll have enough to carry already, and the last thing you need to be lugging around a hefty sleeping mat as well!

If you're going camping you'll likely have a lot of equipment to take with, so it's best to pack as light as possible. This means a heavy air mattress isn't going to go down well (unless you have a car!), so you'll want to check out options for lightweight self-inflating mats or air pads that you can easily set up and pack down. If you're backpacking, something that's small, lightweight, and portable will provide you with more comfort than a bulky mattress.

Guide to Sleeping Pad - Portability

Always think about how you're going to be traveling, and whether or not you'll be carrying the sleeping pad around for extended periods of time. Nobody ever said "I wish my backpack was heavier!", did they? When in doubt, opt for a sleeping mat that's light and can be packed down to a small size so you can carry it easily wherever you go.

Another consideration is how long the sleeping pad takes to set up. After a long day of hiking or backpacking, the last thing you want to do is spend time using a foot pump or pump sack to blow up your sleeping pad. For this reason, foam sleeping pads or self-inflating ones are a good option for those who prefer an easy set up at the end of the day. However, it's important to note that self-inflating mats can be bulkier than other types. 


When searching for outdoor products, you're likely to hear the phrase "R-value" mentioned a lot. This is the measurement given to a sleeping pad's insulating ability. It's calculated based on how much resistance it offers to heat loss from the ground. This is a vital score to take note of when selecting a sleeping pad, as it'll tell you which climate it will perform well in, and which it won't. This way you won't have any unpleasant shocks when you take a low R-Value sleeping mat on a Winter camping trip.

A low R-value won't provide enough insulation to sustain you in cold weather. If you know you're going to be camping in cold weather conditions a higher R-value sleeping pad will provide the insulation and heat loss resistance necessary to rest up with minimal heat loss from the body. There's nothing worse than waking up in the middle of the night shivering, despite the fact that you're wearing every single piece of clothing you brought with you!

It's important to remember that your sleeping pad isn't the only piece of equipment you need to consider for staying warm at night. You'll need to think about whether your entire sleep system is providing adequate warmth and insulation. This system consists of 3 things:

  1. Sleeping bag
  2. Sleeping pad
  3. The sleeper's clothing

When you've got a sleeping bag and sleeping pad with a good R-Value, and you bring along warm clothing, you'll be all set to get a good night's rest (even if it is freezing outside!)


There are a few factors to consider when choosing a comfortable sleeping pad. 

Length: You'll want to choose a pad that fits at least your shoulders and hips. Usually, they come in a variety of sizes, including regular (72 inches) and large (78 inches). Some models offer specific sizes designed for women, as well. If you're focused on choosing a super lightweight sleeping pad, you might want to consider a half or 3/4 length pads that can pack down smaller.

 Width: The standard width for sleeping mats is 20 inches. If you usually move around a lot when you sleep, you might want to think about choosing one that's extra-wide like the Klymit Insulated Static V Lite which measures 23 inches. However, be careful when choosing wider mats if you're buying two or more, as you'll need to ensure they'll fit side by side in your tent.

Baffles: Some mats feature larger side baffles that provide more comfort when you rest by preventing you from rolling off the mat as you turn. These also help to retain heat, keeping you warmer on chilly nights.

 Surface: Another comfort factor to consider is the surface of your pad. A smooth surface might mean your sleeping bag is more likely to slip off during the night, whereas a textured or brushed-fabric surface can help you to remain in place even if you're a restless sleeper. These may also be quieter, as some mats (particularly air pads) tend to be quite noisy which can disturb sleep. 


As with every purchase you make, you'll need to consider your budget for outdoor products. There are plenty of affordable sleeping pad options on the market, whether you're looking for a foam pad, an air pad, or a self-inflating one. It's worth considering how much you'll be using your sleeping pad and weighing up the price in relation to that.

If you're always getting out into the outdoors, then it'll be worth spending a bit more on the price to invest in an all-season sleeping pad that provides support and durability.

If you're on a budget, a foam pad is a good option but you'll need to consider whether you'll be sleeping on it for long periods of time or just occasionally. Self-inflating mats might come at a higher price point, but they usually provide better comfort and less set up. 


1. What is a good R-Value for a sleeping pad?

Sleeping pad R-value ranges from under 2 to 5.5 or more. The lower the number, the less insulation. A sleeping bag or sleeping pad with an R-Value of 2 provides minimal insulation, whereas one with an R-Value of 5 is very well insulated. What you consider to be a good R-Value for a sleeping pad depends on the conditions you'll be using it in. If you're going to be sleeping on it in warm weather, a lower R-Value will suffice (2-3), whereas if the weather's colder you'll need a higher R-Value (4+, depending on the exact conditions). 

2. What is the best sleeping pad for side sleepers?

If you're wondering what's the best sleeping pad for side sleepers, you'll find you've got plenty of options to choose from! Whether you opt for a model by Therm-a-Rest or Klymit that we've covered in this article, or check out other options from brands like Big Agnes or Nemo Tensor; you won't be limited for choice.

First of all, you'll need to consider which kind of sleeping pad to look for. Closed-cell foam sleeping pads are usually relatively thin, which will mean you're more likely to wake up with a bruised hip in the morning. On the other hand, an air pad or a self-inflating pad is thicker and raises you up from the tent floor more, therefore providing more support. When it comes to choosing the right sleeping pad for a side sleeper, pad thickness should be one of your main considerations.

We recommend the Insulated Static V Lite or the Therm-a-Rest NeoAir XLite as one of the best inflatable sleeping pads for sleeping on your side as it provides good support and is wider than other sleeping mats.

3. What should I look for in a sleeping pad?

The most straightforward things you should look for when choosing a sleeping pad are comfort and warmth, what any human to sleep soundly! Make sure to consider:

  • Price
  • Valve quality
  • Set up process (inflation method)
  • Surface texture
