Best Lightweight Sleeping Mats for 2020


Are you in the market for the most comfortable sleeping mat for your hiking and trekking escapes? It’s not an easy choice, what works for one person won’t necessarily work for another.

You need to consider comfort, weight, size – both packed and inflated and then there’s the cost as some lightweight mats come in at a significantly steep price on account of all the new technologies and fabrics incorporated into their design.

Below, we’ve listed our top-selling lightweight hiking mats over the last 12 months, but before we get into the list, let’s cover off on some common questions we get about lightweight hiking mats…

Are hiking mats noisy to sleep on?

Air-filled mats, such as the Thermarest Neo Air (not in this list) and the Sea to Summit air-filled mats, create more noise than self-inflating mats. The good news is that this noise is usually due to the fabric being new, so it will decrease over time. This is usually a small trade-off for a lot more comfort.

What is a bonded sleeping mat?

This question refers to the self-inflating mats, where the outer fabric layer is glued (bonded) to the inner foam. This creates a sturdier sleeping surface and allows the mat to be inflated tightly.

How do I care for my sleeping mat?

Wherever possible always use something between your body and the mat, such as a sleeping bag or liner. This reduces the amount of oil and sweat that soaks into the mat. Should your mat need cleaning, use a mild soap with warm water and a soft-bristled brush to gently clean the surface.

How do I store my sleeping mat?

Self-inflating mats (the ones that are full of dense foam) are best stored inflated. This ensures the foams’ memory is in an expanded state which shortens the time it takes at camp for the mat to inflate. Air-filled mats and air-filled insulated mats are much easier to care for. They are best stored loosely rolled, but if space is a premium, they can be rolled up and stored in their stuff sack once they’re clean and dry.

Storing a self-inflating mat

Store your hiking mat properly so that it stays in good condition for many more adventures.

What size sleeping mat should I get?

If you’re in the ultra-lightweight category, then you’ll probably want to consider the shorter version of any mat. This reduces weight, but you may need to use something else to insulate your feet if the ground is cold. If weight is not a big concern and you just want comfort, or you are a cold sleeper, then choose a mat that is roughly the same length as you are in height.

Width should also be considered, especially for users with larger frames. Women’s sized sleeping mats are usually shorter than the men’s equivalent and often have increased insulation around the feet and hips.

What is R-value?

R-value is an indication of how well the mat resists the transfer of heat from one side to another. This applies to the heat or cold from under the mat, as well as the heat your body may lose into the mat.

The higher the value, the less likely it is you will feel cold from the ground and the more body heat you will retain. for more on R-Value, check out this article here.

As of 2020 you will see a new industry standard for R-Value called ASTM F3340-18. Whilst the concept of R-Value remains the same, the actual testing methods for the value have been updated.

This has been introduced in a bid to create a level playing field for R-Value to help consumers make a better informed choice when comparing the performance of sleeping pads.

The problem currently is that not every manufacturer has tested their mats to this new standard, and you can only really make a true comparison between mats that are both tested to ASTM F3340-18.

We’ll make sure we update information on our website as we receive the latest test data from our suppliers.

Mat Types

Closed-Cell Foam

These are made of a dense foam with thousands of airtight bubbles inside. They do not compress down, don’t offer much comfort, but they insulate really well and are indestructible, lightweight and very affordable.

Air-Filled Mats

These consist of chambers or cells that require inflation before use. These mats usually offer a lot of comfort for their relative weight and packed size. They are not self-inflating and should they get a puncture, will not offer any comfort at all. Insulated versions have chambers filled with synthetic or down to help trap warm air.

Self-Inflating Mats

These are slabs of open-cell foam, often with holes or cores cut out, with a durable-surface-fabric bonded to the foam. This fabric is also sealed on the edges to create an airtight mat. The expanding foam is what creates the ‘self-inflating’ feature, but this also means they require a little more muscle to compress the foam to pack away. The other benefit of these mats is that if a puncture does occur, they still offer some padding and insulation.

Okay, so now that we’ve got those questions out of the way, let’s have a look at Snowys best-selling sleeping mats for hiking over the last 12 months. We’d like to note here that we choose the products we range based on value for money, feedback from our customers, as well as the quality and support from the manufacturer.


10. Oztrail Giga Mat

Despite all the new technologies that go into camp mats to keep you warmer and more comfortable than ever, the good old closed-cell foam mat is still one of the popular choices.

The OZtrail Giga Earth Mat is made with a closed-cell EVA foam and features an eggshell top for increased comfort. These mats are often used underneath another camp mat in alpine environments for better thermal efficiency. They are not the most comfortable mat on this list, but they are reliable.

Comfort Light SI Mat

9. Sea to Summit Comfort Light SI

The Comfort Light SI mat from Sea to Summit got an honourable mention in our list last year, and this year it has earned its spot at number 6. This is a self-inflating mat and boasts some rather impressive specifications.

Usually, a self-inflating mat of 5cm thick would weigh upwards of 1kg but the STS Comfort Light SI defies this coming in at 650g for the regular and 880g for the large. At 5cm thick, it offers comfort for just about any user and offers an R-value suitable for mild to cool weather adventures.

8. Exped Synmat 7 & 9

Providing excellent insulation, and high-quality construction and design that Exped are known for, the Synmat range of mats are designs that have been in our range for years but have experienced a resurgence recently.

Depending on the model you get, these mats offer either 7cm or 9cm thick air-filled tubes that are filled with synthetic insulation. As the tubes fill with air, the synthetic inside expands and helps trap warm air. As an added bonus, these mats have an integrated pump, which when combined with the one-way deflation valve, makes setup and pack-away really easy.

7. Thermarest Prolite & Prolite Plus

Thermarest pioneered the self-inflating mat back in the 1970s when a former Boeing engineer had an ‘Ah-ha’ moment in his garden one day, the Thermarest brand has been synonymous with lightweight hiking sleeping mats ever since.

Of all the mats Thermarest has produced over the last 40 years, the Prolite has been the most popular. These mats have been continually refined year after year and offer an excellent balance of comfort, weight and durability. They come in 2.5cm and 3.8cm thick versions as well as having both unisex and women’s specific cuts, and they are backed with a lifetime warranty.

6. Sea to Summit Comfort Plus & Comfort Plus Insulated

The Comfort Plus mats from Sea to Summit come in both insulated and non-insulated versions. The insulated version is even available in a rectangular shape for a larger sleeping area. Weighing roughly the same as some of the other self-inflating mats on this list, the Comfort Plus mats take things one step further by offering extra height and comfort.

Made with two independent inflatable layers, the Comfort Plus mats provide custom comfort and a level of redundancy in the event of a puncture. While there are lighter mats available, If you’re willing to carry a few extra grams, the Sea to Summit Comfort Plus will reward you with a night of deep sleep.

2. Sea to Summit Ether Light XT

We predicted that these mats would be a hit last year, and boy we were right! The Ether Light XT has given every other mat in this category a run for its money.

Slightly quieter than the Ultralight mats due to the larger baffle design, Ether Light XT mats take it to another level with 10cm of comfort, 3 season insulation, full-body comfort, and almost all at less than 500g a pop! So far our customers have been raving in the reviews about how the thickness is perfect for side sleepers, as your hips and shoulders won’t touch the cold ground.

With insulated, women’s specific and non-insulated versions available, there’s a model for every lightweight hiker.

Why buy this mat: upgrade to more comfort without compromising weight


1. Sea to Summit Ultralight and Ultralight Insulated

These were number one last year and have maintained their pole position again. The Ultralight mats from Sea to Summit features a single layer of inflatable cells that conform to your body when you sleep and come in both insulated and non-insulated versions.

Lightweight hikers love these mats as they are barely noticeable in a pack. They weigh less than 600g for the large version and at 5cm thick, they offer comfort not expected in a lightweight hiking mat, even for side sleepers!

Hexatherm Mat

What to look out for next year

In the past, technical brands such as Sea to Summit and Exped have been the ones to watch when it comes to lightweight mats, but Black Wolf have recently come out with a range of new mats that have our interest due to their design and competitive pricing.

The HexaTherm Hiker Hybrid is a lightweight self-inflating mat that comes in a ¾ size for those who want to cut down on space and weight in your rucksack, and a regular size for traditionalists. It has a 20D ripstop nylon upper with a TPU coating for durability, with a durable non-slip base (so that it doesn’t slide around); a horizontally cored foam inner support system and has a flat recessed multi-function valve to make it super easy to inflate.

We’ve not had much experience with these mats at the time of writing this article, so will have to see how they perform in the long term.

What’s the best hiking mat you’ve ever used?
