Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground.
Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with our Air Sprung Cell™ dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall.
Features:
- Includes an Airstream™ Pump that is integrated into the stuff sack for quick and easy inflation
- Extra thick (XT) loop baffle Air Sprung Cells™
- Lightweight, quiet and grippy 30/40D Nylon fabric, field repairable with included self-adhesive patches
- Ultra-Fresh® anti-microbial treatment is added to the TPU formula to prevent internal mould growth
- Air Sprung Cells™ for a more comfortable sleep
- Multi-functional, high flow-rate valve
- PillowLock™ attaches your Aeros™ pillow to your mat, holding it in place for a slip-free sleep

R-value 3.2
ASTM F3340-18 R-values
An R-value (Resistance-value) is a metric used to rate how effectively your sleeping mat resists heat loss. It’s the only way to know how well your mat will prevent your body heat being leeched away by ground temperatures (which can be a lot colder than air temperatures).
This value can be tested in-house but at Sea to Summit our mats are independently tested at a laboratory to precisely controlled standards.
The new industry standard ASTM F3340-18 testing has now been introduced and all Sea to Summit mats released from 2020 onwards are tested to this standard.
In addition, Sea to summit Ether Light XT Insulated Mat in the Sleeping bags category from your online outdoor store, you can find other products related with Sleeping pad. If you are interested in buying other products from the brand Sea to summit, at trekkinn, you will find a big variety in outdoor products that can also interest you.

excellent
akhaman - 13/09/2023
comfortable and excellent utility, and acceptable weight.
Excellent mattress and no more problems with stones
Marco Schaap - 24/08/2023
Great mattress for a good price. Inflates quickly and deflates quickly. Also sleeps well on your side, you do not suffer from unevenness under the mattress. The combination with a sea to summit pillow only makes it even more pleasant to sleep outdoors.
Comfortable
Johan - 12/08/2023
Very good mattress. Inflates very quickly and the 10 cm are very pleasant.
comfy
jacob - 12/08/2023
Super comfotable, even when sleeping on the side. Easier and quicker to inflate with the sac provided than expected. Reasonably compact, whish it would be a little lighter though.
Very good quality and comfortable mattress

PAOLO - 01/07/2023
mattress really well done down to the smallest detail, very high compared to many competitors but above all comfortable and very quick to inflate / deflate but its strong point is its lightness and compactness.
good sleeping mat
cy - 02/06/2023
very good sleeping mat while camping.
100% comfort
Roel - 20/05/2023
Comfort is incredible. No contact with the floor at all due to the thickness of the mattress. I am a side sleeper and weigh 95kg. Noise nuisance, which is sometimes complained about, was not too bad in my opinion. Because the edges are a little bit higher, you won't roll off either. Two nights of around 5° and absolutely no cold.
Impressive
Bart - 17/05/2023
Unlike previous sleeping mats, this sleeping mat is very comfortable. Used 1 week so far down to 5 degrees at night.
Excellent matt for tall men and side sleepers
Adam - 15/05/2023
I'm 6ft 5 and the long version comfortably takes my height and weight. Easy to inflate and deflate, it offered a warm night's sleep even on a particularly chilly spring night in a damp field. Depth and width makes it ideal for side sleepers. Not the smallest or lightest matt in the world, but for this price it's exceptional.
Good mattress
Emilie - 03/05/2023
Comfortable, I recommend!
Comfortable cushion
Danny Mao - 20/12/2022
This mat satisfies my habit of sleeping on my side when camping. It is very comfortable, but it makes a noise when I turn over. It is annoying but everything is fine.
Best one
Sidney - 06/10/2022
Best mat you can get. Worth getting the extra width
Comfortable and easy to use
Dmitri - 03/10/2022
Very happy with this mat. It's thick, comfortable, warm. Used it to sleep on rocky or heavily rooted surfaces and it performed really well. You can inflate it very fast and easy by using storage bag as a pump and also it's very easy to fold back. More comfortable and easier to use than self-inflated mat that I also own. Can be a little squeaky on some surfaces, but much less than other brands. I am also using the Aeros pillow with it, and it works very well for me. Great value for your money.

very comfortable. 100% recommendable
Top mattress
Bruno - 22/09/2022
Accustomed to more basic mattresses, this mattress has transformed my bivouac nights. Incredible comfort, associated with the pillow, it's like in bed (almost...). The inflation bag is very practical once you have taken the hit. Storage bag well suited, no hassle. Weight and compactness at the appointment.
Very good air mat
reinerberge - 29/05/2022
After Therm-A-Rest and Exped, now a Sea to Summit insulated air mat. I bought it mainly because of the height as I like to sleep on my side. She's really perfect for that. There is a deduction for the volume of the mat when turning, others are quieter. It is also a bit big and heavy and has a low heat value. All in all I'm satisfied so far.
Sea to summit mattress
Piga Giordano - 05/05/2022
Comfortable and warm and its 10 centimeters thick allow a good sleep even if like me you are used to sleeping on one side ... excellent weight distribution if we were not in a tent it almost seems like the mattress of your own home !!!
super good
samet - 18/04/2022
comfortable, light , easy inflatable, warm , strongly recommended
超讚

比預期中還要早收到,太棒了! 目前還沒有使用,超級期待下個月的戶外活動,希望會有不錯的體驗
Good
Marco - 21/12/2021
Comfortable, warm. Quick and easy to inflate with the pump bag. The size of size M is right for me which is 1.68, although I would have liked it slightly wider, like the female version. But it must be said that there are few mats that are wider than this one. I had a Klymit that was wider but there is no comparison in other respects.
Really comfortable mat
Klaus - 10/12/2021
The mat is really comfortable in contrast to my previous mat with "longitudinal tubes". Pack size and weight is great. The pump bag is acceptable, according to the operating instructions you should blow into it at a distance, which I don't do because of the moisture. Therefore it takes a little longer to pump. The slight rustling of this type of mat is not too annoying. I think the price performance is good and the convenience is really great.
Great value
Pamela - 06/12/2021
Comfortable sleep. Highly recommended.
Awesome
Antonio - 13/07/2021
Mattress show. Maybe there is something more compact on the market, but this one has its 10 cm thickness that makes the difference in comfort. The integrated bag that acts as a pump for inflation is also very comfortable
Fantastic
Giovanni - 23/06/2021
I bought 2, very light mattress very easy to inflate. Perfect for bivouac, I travel by motorbike and I need light weights and little bulk. HIGHLY RECOMMENDED !!
Top comfort
Nikos Athanasiadis - 18/06/2021
Top quality insulated mat .It comes with a pump sack and a repair kit which is also amazing and it requires just 3 full pump sacks to be ready. Not only this but the regular size weights just 490 grams !!
Super Confortavel
Everton de Oliveira Lourenco - 18/05/2021
A nova versão além de vir em um cinza claro muito bonito é bem silenciosa e não faz barulho quando voce se meche.

As a side sleeper, I have finally found a mattress on which I don't wake up with shoulder pain.
Lightweight sleeping mat
Elizabeth - 14/04/2021
Very comfortable, lightweight and easy to pack sleeping mat. Easy to inflate and deflate. Item arrived quickly too!
Awesome
Roy - 08/04/2021
It’s super easy to inflate and deflate, decently light and compact for easy toting, but impressively comfortable thanks to the high volume and 10cm thickness.
Great, functional
Roberto - 27/03/2021
Very light and easy to inflate mattress. Insulates well from the ground and can be inflated / deflated easily thanks to the valve. Perfect for those who go hiking, bivouac and need light weights and little bulk.
Awesome product
Donna - 04/03/2021
With the Covid, I started hiking even in the middle of winter and this ultra light, comfortable and very insulating mattress which, in addition, inflates and deflates particularly easily, quickly became an essential accessory for my outings. By far the best hiking mattress I have ever had.
Great rug
Пётр - 20/02/2021
Even better than expected, I thought it would be quite narrow, I am a very large friend, but it turned out to be quite comfortable in size. Lie very comfortable, soft. Inflates quickly, folds comfortably and also quickly. Before that it was self-inflating, this one is not inferior at all. But of course much smaller and lighter. A pillow is a must, you feel at home with it! The only thing is that when you kneel on the rug or squeeze with your elbow, you immediately reach the floor, the ground. Those. sleep comfortably, but there is a peculiarity.
Great product!
Coll - 13/02/2021
Great product !! This mattress is great, (the best for bivouac!) And Trekkinn is a trusted site! I highly recommend
Assessment
Andrés - 29/11/2020
Excellent Trekkinn compliance. Highly recommended. Perhaps the only drawback I see is the customer service area.
Upgraded
B, Spillane - 28/11/2020
I have two exped mats 51cm wide(narrow) . I needed something wider after I upgraded from a Bivy(narrow) to a TarpTent moment Dw(wider). Haven't been out yet but first impressions are really good. Stuff sack/pump bag is dead handy. Light weight and it comfortable to lay on. Seems very well made.
Great
Francesco - 29/08/2020
Arrived in 10 days as per description. The mattress is really comfortable and the built-in air pump is really well made and comfortable.

Very very comfy, packs in really low volume. Easy to inflate. Pillowlock system is a hoot. Fantastic price from trekkinn
Excellent mattress
Mikael - 08/08/2020
Extremely comfortable mattress to sleep on, didn´t feel even a bit of cold coming from below me when sleeping on a Finnish forest floor in a tent. Extremely easy to fill with the stuff sack that comes with it.
Very comfortable
maurizio - 30/07/2020
One of the best mattresses in terms of value for money. Very comfortable given the thickness of 10 cm and when closed it takes up very little space
Sea to summit ether light XT Insulated
R - 28/07/2020
Used this mat last week on a camping trip on a scottish island. Very comfortable did not once need to be re-inflated. Well worth the money spent .
Really good Mat
Carolina - 27/07/2020
This is a really good Mat. We had the precious skinnier model of the sea Ros unit mats and this is much better and much more comfortable!! It’s the closest thing you’re going to be able to have while camping ultralight!!
Review
Sofia - 23/07/2020
Great! You can lie on your side without touching the ground, which is what I wanted to achieve. Folded, the mattress is light and small in relation to the comfort level. It sounds a lot when you turn around But it does not matter to me. Smooth and hygienic with the integrated pump!
Lack of a real after-sales service, unacceptable !!!
arpino sabine - 21/07/2020
What setbacks with this site. Mattress arrived a year ago, pierced not holding inflation .... in my living room !!! After having finally succeeded in having an interlocutor in French, I send photos and then return the mattress which comes back to me like a ladybug full of colored patches ... and still not holding the inflation !!! :) We have me promised a refund never arrived and instead I am returned a defective product. I gave up and this mattress is languishing in the back of a cupboard .... at this price it is unacceptable .... Sabine
Review
Iyrii - 14/07/2020
Very high quality rug. Recommend to buy
Comfortable and well finished mattress
PASCAL - 10/06/2020
Finally a mattress that allows you to sleep on your side, it certainly does not equal the comfort of your cozy bed but it is closer to a comfort worthy of the name. The finish is good and the anti-puncture kit is quite nice. If the weight of this mattress is a little higher than my previous ones, it is because it has in its carrying case the famous inflatable system, very practical, no need to empty its bag sometimes badly stored to find the inflatable bag. This SEA TO SUMMIT is also less noisy than my EXPED SYNMAT and will tend to slip less because of its more "eye-catching" velvet fabrics. Remains the price, quite expensive, fortunately at a very good price on the TREKKIN site, 130 euros instead of the 170 euros observed in general. The delivery was a bit long, but I think this is due to COVID 19 and the delays that have accumulated. In short, I recommend the site and the mattress.
Wonderful
Moa - 04/06/2020
Haven't been able to test it for real yet. Was a good moment on the living room floor though, on the side. Anyway. Will put it to the test when we walk the King's Trail this summer :)
Comfortable mat
Akihiro - 14/05/2020
You can sleep comfortably without facing the ground even if you turn to the side
Sleeping wonderfully
Marije - 28/04/2020
Sleep wonderfully, nice and warm and wonderfully light
Very good first impression
Vincent - 28/04/2020
Just tested once in a tent (temperature of 11 ° harms me) and I was not cold. Very comfortable and easy to inflate mattress. It is light and quite small when folded. Convenient for those who sleep on the side. I took the size Large which is perfect for my size: 1.90m and 84kg. Smaller would have been too small.
Excellent rug.
Igor - 23/04/2020
Very comfortable rug. Not noisy. Wider than Therm-A-Rest. Delivered in 7 days to Russia.
Perfect Mat
Ondřej Kraus - 15/04/2020
Most comfortable mat ever. I thas good R-value, it is lightweight and cost effective here on trekkinn.
Nice mat
Ondřej Kraus - 15/04/2020
Most comfortable and ultralight mattress ever. With R-value 3.2
Satisfied! great product
Antonio - 09/04/2020
Product as per technical data sheet. A few grams more than other models but decidedly comfortable, with its 10 cm thickness, for those who sleep on their side Weight controlled with a precision balance, corresponds to what was declared by Sea To Summit. It inflates comfortably effortlessly with its practical bag. It deflates quickly and impressively by opening the valve completely! I confirm that RValue has dropped 3.2. Tracked shipping and punctual delivery as per notice.
Comfortable mat
Jes Larsen - 04/04/2020
Quite ligthtweight, very comfortable (even when laying on the side) and easy to inflate with the pumpsac. I haven't tested it outdoor yet.

Very comfortable
Luciano - 31/01/2020
The most comfortable pad I´ve ever used. Pay attention, the R Value decreased with the new standard of measurement to 3.2.
Excellent product
German - 07/12/2019
It is simply perfect, very comfortable, almost like sleeping at home, easy to inflate, very resistant and silent to move over it. The space it occupies is almost nil, very good investment. The custom and dispatch service was very efficient.
Good spoon

Fine mat
Tom - 08/11/2019
Nice mat!
Delicious mat
Jaco - 05/11/2019
Tested immediately, what a super mat. As a side sleeper always struggling to find a nice mat, but this one is great! Only the delivery time of 2-3 days to the Netherlands is incorrect, I had to wait a week for it.
Excellent Insulated Mat!
Dmitry - 19/09/2019
Very lightweight and compact rug! Inflated quickly with a pressure bag. It does not break even while sitting.
Excellent mattress
Paulina - 02/09/2019
It is the best by far, people who have trouble sleeping like me and had stopped camping for bad nights, now with this, one can go back to camping and get a comfortable and warm sleep. I recommend it 100%
Super happy with the purchase
Felien - 28/08/2019
Ultra-comfortable mat, very easy to inflate with the pump bag and is also quickly emptied and rolled up again. I recommend it to everyone!
Best mat ever
Arch - 18/08/2019
Nice thick sleeping mat. Is perhaps even more comfortable than a normal bed. With the pump bag the mat can be inflated very quickly and the mat stays nicely dry inside. The mat is also nice and warm to sleep on. No problems with cold from the ground. Very small on the roll and nice and light. A big improvement on the self-inflatable mat that I had before.
Works!
Anttu Pekkarinen - 05/08/2019
Comfortable sleep. There will be no sore spots. Also nice light. If the surface material was not loud, this would be perfect.
Great sleeping pad
Anttu Pekkarinen - 05/08/2019
A couple of weeks in a row come to sleep on top of this and I am very happy. It has a lightweight and compact footprint, and sleeping comfort is best in class A. The first platform that does not become sore. The only minus comes from the soundproof surface. Coating when you could still get it done this would be perfect!
Sea to summit ether lt xt insulated mat
Sergey - 22/07/2019
Back to back on the side.
Most comfortable lightweight mat ever for side sleepers!
Scott - 15/07/2019
My search is over! I'm ultralight backpacker and have tried lots of mats over the years, especially ultralite options from Exped (failed at the valve), Thermarest (xlite - great but noisy and easy to roll off to the side, and hard to deflate quickly, and it gets moldy) and Sea to Summit (loved their UL mat overall, but it was too thin to keep me from bottoming out when on my side and moving around). Sure, the Ether Light XT is a bit heavier, but it is more than worth the weight penalty. I'll now exclusively use this mat, also for backpack travel in civilization when I need a mat to toss on the floor at people's homes.
Super!!!
Igor - 13/06/2019
I will sleep like a king! Workmanship and materials for 5+. With an increase of 184 cm fit on a rug of size L with comfort. Includes a repair kit and stickers for fixing the pillow. Fantasy!
Super comfort
Владимир - 06/05/2019
Incredibly comfortable, warm and thick rug, very reminiscent of a regular orthopedic mattress.
