A sleeping mat is a vital component of our kit list alongside a good sleeping bag if you want a comfortable night on the hills with a tent. A sleeping mat can be the difference between a decent night’s sleep and a very bad one. The best sleeping mats won’t just be comfortable to lie on but they’ll also keep you warm and that’s why insulation performance is perhaps the most important aspect of a sleeping mat to consider.

Sitting on a rock on the summit to enjoy the view on a chilly day, one can feel the warmth draining away – now imagine that same effect along the length of one’s entire body, all night. And our sleeping bag is only half the story. As insulating as it may be, our body weight flattens out the insulation below us and minimises its effectiveness. The right sleeping mat will prevent downwards heat loss from your body and this should make your night safer and more comfortable when using a sleeping pad.

A smaller pack size and weight are welcome when carrying something to a high camp, and it’s worth experimenting to get the best fit. sleeping pads are usually sold as solid, rolled-up cylinders, but you can flatten them and fold them into your pack. Careful pitching is important. It’s easy to tear and deflate mats by catching a sharp rock under the tent, or accidentally rolling over onto crampons or stove parts in your sleep. Make sure you can repair a puncture, either with the manufacturer’s kit or your own.

Practising inflation and deflation is also worthwhile – wrestling with new kit in a cramped tent in the rain is no fun at all!

How we tested them

Woodland ranger and outdoor gear expert Peter Macfarlane conducted our sleeping mat tests here. To achieve a consistent testing environment and accurate comparison, the mats were used in the same bothy and with the same 3-season sleeping bag in similar damp and cool weather conditions. All the sleeping pads were weighed by Peter on his own digital scales.

Alpkit Cloud Base

Alpkit-Cloud-Base has been given a recommended in our guide to sleeping mats

  • Pros: Weight and packability, price
  • Cons: Low R-value
  • RRP: $64.99 | £50
  • Weight: 506g
  • Rating: 4/5

Type: air | Materials: 20D nylon with TPU laminate | Dimensions: 189x56cm | Thickness: 5cm | Sizes: one size  | Rating: R-value 1.4

The Cloud Base sleeping pad has a different construction to the other models in our test of the best sleeping mats, consisting of a matrix of air pockets in two different sizes. This gives it a distinctive texture and helps to keep feet from slipping off the tapered end of the mat. On rough ground, it does bed down well and inflation and deflation are simple. It packs down to 28x8cm in its stuffsack and comes with a puncture repair kit. Its low R-value makes it a fair-weather-only choice, but its relatively modest weight and robust fabric make it an excellent choice for wild camps in the summer hills.

Therm-a-Rest NeoAir XLite NXT

best sleeping mats: Therm-a-rest NeoAir XLite NXT
SQUIRREL_BUTTON_12925678

  • Pros: Weight, packability, warmth
  • Cons: Price
  • RRP: $209.95 | £210
  • Available from Amazon
  • Weight: 378g
  • Rating: 4/5

Type: air | Materials: 30D rip HT nylon, polyurethane | Dimensions: 183x51cm (R) | Thickness: 7cm | Sizes: Short (330g, 168x51cm) + Regular + Regular Wide (440g, 183x64cm) + Regular Long (470g, 196x64cm) | Rating: R-value 4.5

This mat gained the top spot in The Great Outdoors Awards for 2023, with the jury recognising it for its Thermacapture lining, a heat reflecting layer within the mat that ups its R-value to an impressive 4.5. The previous version of this mat had a reflective lining, but this was rustly and made for a noisy sleep. With this new version, Therm-a-rest have got rid of that issue and upped the insulating value without adding any extra weight,

“The ThermaCapture material within the previous mat would rustle whenever you moved,” said Will Renwick. “That problem doesn’t exist any more. It offers an extremely comfortable, warm and a quiet night’s sleep now.”

The NeoAir is a compact, rounded mummy shape and a small pack size of 20x13cm. It is easy to inflate with the pump sack that comes with it and has a repair kit with cleaning wipes and stick-on patches. Performance and low weight make it an excellent choice for high camps and multi-day trips, but it does come at a premium price.

Nemo Quasar 3D Insulated Long Wide

Nemo Quasar 3D Insulated Long Wide

SQUIRREL_BUTTON_12925679

  • Pros: Comfort, warmth
  • Cons: Weight 
  • RRP: $199.95 | £200
  • Available from Nemo Equipment
  • Weight: 944g
  • Rating: 3/5

Type: air | Materials: 30D 100% PCR PU polyester ripstop, bluesign-certified, PrimaLoft 100% PCR | Dimensions: 193x64cm (L/W) | Thickness: 9cm | Sizes: Regular (790g, 183x51cm) + Regular Wide (930g, 183x64cm) + Long Wide | Rating: R-value 3.3

The Quasar sleeping pad is a comfortable and secure sleeping mat, but it is heavy and the large stuffsack pack size makes it best suited to lower-level camps. Thick, 9cm deep side-to-side baffles and the large footprint result in a squishy mattress and the potential to feel the ground when sitting or lying on one’s side. The R-value is high at 3.3 with Primaloft recycled insulation for cold-night comfort, and the included repair kit is faff-free.

Therm-a-rest Prolite Plus Short

Therm-A-Rest Prolite Plus

  • Pros: lightweight, compact, comfortable, warm, durable
  • Cons: nothing
  • RRP: $105 | £110
  • Available from Alpine Trek
  • Weight: 0.99 lb | 450g
  • Rating: 5/5

Type: self-inflating | Materials: polyester shell, diagonal-cut foam inner | Dimensions: 119 x 51cm | Thickness: 3.8cm | R-value: 3.2

This lightweight sleeping mat has been used extensively by our gear editor Chris Townsend who gave it a gold star 5 out of 5 review. “This is the best mat reviewed for warmth, weight and cost,” says Chris. “It’s suitable for year round use – I’ve slept on snow and frozen ground and felt no ground cold coming through.”

It’s a short mat that’s designed for those minimalists who, for the sake of keeping their pack weight low, are happy to forgo any padding or insulation from the knees down. In mild to warm conditions when the ground temperature isn’t low, many backpackers will find this will be more than adequate for a good night’s sleep. That’s said, those who like a bed-like luxuriously soft and cosy night’s sleep might want to look elsewhere.

This mat uses an open cell foam insulation structure, so it sits in the middle between fully inflatable sleeping mats and classic closed cell foam mats. This means it doesn’t have the bouncy, lilo-like feel of an air mat but also has the slightly chunkier packed size of a closed cell foam mat.

It’s fully self-inflating. All you need to do is open up its valve and it’ll do all the hard work itself – though it will usually require a puff or two just to get it up to pressure. It’s also, from our experience, quite durable too. That’s thanks to its high denier fabrics which are designed to withstand a bit of abrasion.

Lomo Folding Camping Mat

 Lomo Folding mat

SQUIRREL_BUTTON_12925682

  • Pros: tough, can’t deflate, low cost
  • Cons: bulky, not that comfortable
  • RRP: £20
  • Available from Lomo
  • Weight: 0.90 lb | 410g
  • Rating: 4/5

Materials: closed-cell cross-linked polyethylene (XPE) foam | Dimensions: 180 x 57cm | Thickness: 2cm | R-value: 2.0

This comes recommended by TGO gear editor Chris Townsend who awarded it four out of five stars following his tests. It’s a mat that can be used by itself during summer camps and then, come winter, it’ll serve excellently as that extra layer of insulation underneath an inflatable sleeping mat. Made from closed cell cross-linked polyethylene foam, this type of sleeping mat is lightweight and quite small in packed size and, perhaps more importantly, it’s also very durable and reliable, being capable of withstanding the kind of punctures and abrasions that would condemn an inflatable mat.

The reason it’s shiny, by the way, is because it has a heat reflective coat and it also has little eggbox-like idents to trap insulation. The R-value is therefore a respectable 2.0.

This costs substantially less than most inflated options out there, making it a great value option for casual campers.

Features to look for in a sleeping mat

R-value and shape

The R-value is a standardised measure of resistance to heat loss. When applied to sleep mats the R-value indicates how well the mat will insulate us from the ground temperature. A low value around 1 might be adequate on summer camps, whilst a value of 4 or above will help to insulate against frozen ground.

Typically, sleeping pads come in two shapes. Rectangular mats offer improved comfort and allow us to move around in our sleep with less chance of touching the ground, but they take up more floor space and will weigh more. Mummy mats taper towards our feet and work well in smaller one-person tents, but feet can slip off more easily whilst asleep.

Weight

If we’re based at a low-level campsite and walking the hills with a return to camp for bed, a larger and heavier mat will likely be fine. If we’re carrying our overnight gear across the hills, a lighter mat will be very welcome. There is always a balance to be struck between weight and performance, depending on our plans.

Inflation

Self-inflating mats have compressed foam inside that expands when the air valve is opened. All the mats in this review must be inflated manually. All can be inflated by blowing into an air valve on the mat itself, but some models come with extra sacks that can be used as bellows to inflate the mat.

These can prolong the life of the mat by reducing moisture inside (from one’s breath), but can be fiddly and time-consuming, especially in restricted tent space. It’s worth noting that mats don’t have to be fully inflated, and that you can adjust for your own comfort level.

Variety

Some products can still be found in a women’s-specific format, with differing levels of insulation and different sizing. Current models come in different lengths and widths so you can pick one that best suits your body shape.

Fabric and construction

The fabric used must be supple and durable enough for multiple inflation and storage cycles. It must be puncture-resistant to prevent a night on cold or stony ground. Look for puncture repairs kits included with your mat, or take your own on camps.

Construction types vary greatly from simple sheets of foam to down-filled mats for sleeping on snow. Here we’ve concentrated on a middle range, useable in varied conditions (outside the true depths of winter). Fabric and manufacturing technology have advanced greatly, meaning that modern mats can achieve a relatively high R-value without incurring a weight penalty.

Sleeping mat construction: a guide to the different types

best sleeping pads: Rab Ionosphere

While all sleeping mats might be designed with the same end goal in mind – providing a comfortable night’s sleep – there’s a surprisingly amount of variation in how some sleeping mats are constructed in comparison to each other. Some are very simple and just involve a sheet of foam, others are more complex, involving closed cell foam or interlinked air chambers. Here are some of the options and their advantages and disadvantages. 25

Foam Mats

Foam mats are a classic and reliable option for lightweight camping. Constructed from closed-cell foam, these mats provide a degree of comfort and insulation. The solid foam construction makes them highly durable and resistant to punctures, making them suitable for rough use and rocky terrains. They are among the lightest sleeping mat options available, making them ideal for ultralight backpackers. Foam mats offer decent insulation, making them suitable for three-season camping. Additionally, they come in various shapes, including rectangular, tapered, and mummy-shaped, catering to different preferences and body types. Foam mats are often used in winter as an extra layer of insulation underneath an inflatable mat.

Self-Inflating Mats

Self-inflating mats are a popular choice among campers due to the amount of comfort they can provide. These mats are designed with a combination of open-cell foam and an air valve that allows the mat to inflate partially on its own. The foam core provides cushioning and insulation, while the air valve allows air to enter, expanding the mat to a certain degree. To achieve the desired firmness, you may need to add a few breaths. Self-inflating mats offer good insulation, making them suitable for three-season camping and colder conditions. The combination of foam and air creates a comfortable sleeping surface that balances support and cushioning.

Inflatable Mats

Inflatable mats, also known as air mats, rely on air for cushioning and support. These mats are designed to be lightweight and packable, making them a popular choice for backpackers. They have one or multiple air chambers that you manually inflate with a pump or your breath. The materials used in inflatable mats, such as nylon or polyester with TPU coatings, provide both durability and comfort. Inflatable mats offer excellent cushioning and can be adjusted for firmness to suit individual preferences. When deflated, they can be compacted into a small size, making them easy to carry in your backpack. The level of insulation in inflatable mats varies, and some models are designed for specific temperature ranges or seasons. Additionally, inflatable mats come in different shapes, including rectangular, tapered, and mummy-shaped, offering options for various sleeping styles and space preferences. The main risk with these types of mats is that they can quickly become unusable if even just a slight puncture occurs and, due to that risk, it’s a good idea to carry a puncture repair kit with you.

Baffle Designs

Apart from the type of sleeping mat, the baffle design also plays a significant role in comfort and performance. Baffles are the internal compartments that hold the air or foam within the mat. Different baffle designs include horizontal and vertical baffles. Horizontal tubes run across the width of the mat, providing even support but with a risk of some shifting of air or foam during the night. Vertical tubes run the length of the mat, offering more stability and preventing air or foam from shifting as much during sleep. In addition to baffle designs, you’ll find tapered mats, which are narrower at the feet and wider at the shoulders. These mats save weight and space while still providing sufficient support and comfort. On the other hand, rectangular mats offer ample space and freedom of movement, making them suitable for those who prefer sleeping in various positions.

Understanding the different types of lightweight sleeping mat constructions and baffle designs will help you select the most suitable option for your camping needs. Consider factors such as insulation, comfort, packability, and shape to ensure a restful and enjoyable night’s sleep during your outdoor adventures. Happy camping!
