Sleep comfortably on your side on lighter adventures in colder conditions with the Ether Light XT Insulated Mat from Sea to Summit.
The Ether Light XT Insulated has large air pockets created from looped TPU baffles and has a height of 10cm so your hips can sink in without touching the ground. To help keep you warm, this mat has THERMOLITE® insulation and Exkin Platinum® to reflect radiant heat. This mat is from a 30/40D nylon fabric which provides a grippy and durable surface that’s also field repairable with included adhesive patches.
Deflate and adjust your mat easily with the multi-functional high flow rate valve, and inflate it efficiently with the Airstream™ Pump integrated into the stuff sack. To prevent mould growth, there’s an anti-microbial Ultra-Fresh™ treatment and it’s simple to attach a separate Aeros™ pillow as there
For additional comfort when the temperatures drop without the excess weight, you can depend on the Ether Light XT Insulated Mat from Sea to Summit.
I took a measuring tape and put it on 64cm, it looks short
G'day Kevin,
Yes, that's correct.
Standard, self-inflating car camping mats in a single size generally range between 63-69cm wide, so considering this is a hiking mat, the width is pretty good.
I'm 181cm what size would you recommend? I know it subjective to the individual. My concern is the extra 2cm on the regular might be cutting it very close. Thank you
G'day Ken,
I think it depends what your primary usage for the mat is. Most people looking at these mats are multiday hikers, and so would go for the regular because keeping weight and pack size down is important.
2cm is cutting it fine for residential sleeping, but on the trail expectations can be different. You'd be pretty tired after a long day of walking, so likely to sleep well regardless, and inside a sleeping bag you won't notice as much if your feet are close to the edge. Most people also sleep abit more scrunched up than perfectly straight, so I think you'd be ok with a regular.
If you are a bike packer, motorcycle tourer, or Kayaker, etc where pack size and weight can be alittle more flexible, then go for the larger size if you are concerned.
Hope that helps in some way!
Just wondering if the included stuff sack is waterproof? Or would I need a dry sack if I am strapping this outside my back for hiking?
G'day Cass,
The stuff sack isn't waterproof, we would definitely recommend a dry sack if you're expecting to get wet!
Hi - would a regular and large fit in the pro hiker 2 tent?
G'day Adam,
We can work this one out by checking out the dimensions.
The sleeping area of the Pro Hiker 2 is 215L x 140W
The large Etherlight is 198L x 64W and the Regular 183L x 55W , which gives you 20cm of room to play with in the tent.
Hope that helps.
Which would you pick between this and the STS ultralight mat for a 4 season mat?
G'day Brendan,
The Ether Light XT Insulated has a slightly higher R-value and is slightly thicker than the Ultralight Insulated, so it would be slightly better suited for colder conditions. Technically speaking, they're both 3-season mats, so if you want a true 4-season mat you'd be best looking at the Ether Light XT Extreme Insulated.
Based on the recent change to the R-value, how does this compare to the Comfort Light (green)?
G'day PT,
The new ASTM R-Values are listed on the product pages for the Ether Light XT Insulated (3.2) and the Comfort Light Insulated (3.7). Therefore, overall, the Comfort Light Insulated has slightly better insulation using the new testing protocols.
Hi, im trying to work out the differences between this mat and the womens version apart from the shape? I see that they are both 10cm thickness and this mat comes in rectangular version which im leaning towards because my current mummy shaped mat i keep sliding off. And would this be suitable in cold weather? Thanks!
G'day Kristen,
The women's model and the unisex models are the same in terms of thickness and materials. The differences come down to the shape. The women's models are shorter, and a little wider at the hip than the unisex model, so a little less mummy shaped. All of the different models have a slight different R/ASTM value, so double check there, and have a read of our blog about how to interpret this in terms of temperatures. Overall the rectangular model will give you the largest sleeping area, however they are heavier than the other shapes.
Hello, we're looking at upgrading our old gear to the Zempire Zeus Hiking Tent, which I see is 140cm at the head, 125cm at the feet. Would we manage to fit 2 large tapered mats or 1x large tapered and 1x regular tapered mat? Miss 171cm tall and Mr 187cm tall, but lean beans. Open to other suggestions!
G'day Leonie,
You should be ok with a Regular and a Large Ether Light Mat in your Zeus, however you won't really have any room to spare. Most of the mats are around the same width, with the Large models being a little wider than the Regular. You'll fit, it will just be a bit of a squeeze, unless you wanted to upgrade to a larger tent!
Depending on size, would these be OK to use in a swag ( it's 200L x 75W cm's x 60 high? They look great.
If the size fits, then I can't see any reason why you couldn't use this in a swag, Ian. It would make your swag much more compact for transport.
As above
G'day Zeb,
You'll just need to select the small size mat in the drop-down menu which will update the size. The small mat is 0.470kg, 168L x 55Wcm.
Does it have the pillow patch to stop S2S pillow from moving off mat ?
G'day Zeb,
Yes, the Ether Light XT Insulated Mat has the Pillow Lock patches. You'll just need to adhere them to the mat when you receive it.
Hi there. I popped into the store about 8 months ago to try different pads for my hiking kit. I walked away feeling that the Exped 9LW was the most comfortable (1.15kg) followed by it's thinner 7LW (1.05kg). I don't think the Ether Large Rec was there to test the day I was there. Compared to the regular Ether Reg size (can't remember if it was tapered or rectangle), I found the Exped far more comfortable but I'm wondering what your thoughts are when comparing this Large Rec Ether v the 7LW or 9LW? .. I'm willing to take a hit in weight for my pad, but if the large Ether closes the gap to negligible difference in comfort, then the 400g saved is a bonus. Cheers
G'day Daniel,
The Exped Downmat 9LW is a great option, but the Ether Light XT Insulated Large Rectangle is also a great option. As you indicate the Ether Light XT is much lighter than the Exped so you will save yourself a fair amount of weight. In terms of comfort, to me they both feel pretty comfortable, so I guess it depends on what you're used to. The Ether Light XT Insulated Large Rectangular is a newer model so it's possible we only had the tapered models when you trie them out in-store. The Exped has a much higher R-value so it will be suitable for use in snow conditions, while the Ether Light is really designed for Spring/Autumn conditions, and some Aussie winter. Overall we think they're both great options, but the weight and R-value tend to be the tipping factor for most.
Hi Lauren, thanks for responding to my last question, however, the title and crux of my last question was in regards to the width of the large and regular tapered mats at the foot end. I know they are 64cm and 55cm wide at the top, but what width do they measure at the bottom? Sea to summit don't include these specs on their webpage either. Thanks, Adam.
G'day Adam,
The foot end of these mattresses measures 30cm across at the bottom end and about 10cm up the width measures 40cm across. Hope this helps!
Could you please tell me the dimensions of both the regular and large tapered mats at the foot end? Also, would 2 of the large mats fit inside the Wilderness Equipment Space 2 tent, or would I need 2 regular sized mats? I believe the tent has a continuous taper from 1300mm at the head to 1060mm at the feet. Additionally, the mats appear parallel for the first half and then start to taper around halfway down (although this is hard to tell from the pictures) meaning they might fit at the top and bottom of the tent but would be to wide for the mid-section. Thank you for your help, Adam.
G'day Adam,
Thanks so much for your question!
Unfortunately, we don't have a Wilderness Equipment Space 2 on display but based on some quick calculation of all the specs provided the Regular Ether Light XT Insulated would be the way to go.
The Space 2 head end width is 130cm, the Large Ether Light XT Insulated mats are 64cm wide, so that cutting it too fine in my opinion.
In terms of the tapered mattress fitting inside the tapered tent, my thoughts on this are that Sea to Summit are a very experienced outdoor/adventure gear company, and alot of thought and research goes into their product design. In my own personal experience using an Ether Light mat I'd say you have nothing to worry about with 2 x regular mats in the Space 2.
Hope that helps.
Does the large rectangular (201L x 64W cm) fit the Zempire Atom tent without causing the inner and outer tent to touch? Will you be getting any large non-rectangle ones into stock?
G'day Kay,
We don't currently have a display model tent to double-check this for you, but I'm fairly confident the large rectangular model will be a little bit too big with the tapered corners on the floor of the atom. We've just sold out of the old model Ether Light XT Insulated Large, so we'll get the new model up online in the next day or so. We're expecting the stock to arrive in the next two weeks.
Are you able to confirm a large rectangle is too big for an atom? If so problematic big or just slightly pressing the inner
G'day Grant,
It is definitely too big, I'm sorry. You don't want your mat to be touching the tent inner at all, because it creates a wicking point or a drip point & your gear will get wet.
In this particular case you'll struggle to get the mat in at all, and we don't recommend it for use with the Atom.
Does the mattress need to be stored inflated to prolong the life of the insulation? Or is it ok to store compressed?
G'day Thomas,
I've just had a chat with Sea to Summit on the best way to store this mattress. Their recommendations are to not store it in the stuff sack but to store it flat with as few folds as possible, make sure it's dry and aired out, and to keep the valve open.
Hi guys, i'm looking for a mat to pair with the Sea to Summit Ascent Ac2 Sleeping Bag (-4 °C) so wondering if this mat is warm enough and how it stacks up to the Exped Downmat 9LW Sleeping Mat
G'day Joel,
R-Value is the measurement of insulation's ability to resist heat flow. R-Values range from 1.5 upwards and the higher the insulation's R-Value, the better that product is at retaining your body heat. So an R-Value of 8 will do a much better job at keeping you warm than an R-Value of 3.8.
Quite a few reviews refer to noise on other mats but the description of this one implies it’s less noisy
G'day Sim,
The new Ether Light XT Insulated Mats are found to be quieter than the other Sea to Summit air filled mats. They have a slightly different design with larger baffles that not only means they are quieter, they are also lighter for their equivalent thickness.
Hi Sim, I can answer from experience - I used one of the early STS mats with the interlocking air cell design (yellow, whatever that corresponds to) and now own an ether lite xt therm. The difference is light and day - this pad is much much quieter and far better than the equivalent Thermarest. Also super comfortable (the old STS was awful).
I’ve been tempted by the current UL hiking mats, but the noise has always turned me off .. it appears this next release will not have noise issues. I am not sure of the difference between 30/40D Nylon and 40D ripstop though.
