The Sea To Summit Ultralight Insulated Sleeping Mat completely redefines what we perceive as a comfortable and lightweight mat for trekking and hiking.

This lightweight sleeping mat is dot weld constructed to create air filled cells that function in a similar manner to pocket spring mattresses. Confidently do away with a pump and inflate the mat with your breath, the durable rip-stop fabric is extrusion TPU laminated and has an antimicrobial treatment to resist the growth of mould.

The body conforming air cells combine with Thermolite® insulation and heat reflective silver coated Exkin® Platinum fabric in a comfortable, compact and lightweight package that may generate fits of jealousy amongst fellow lightweight hikers.

  • Insulated, air filled mattress
  • Multi-function inflate/deflate valve
  • Individually factory tested
  • Antimicrobial - OK to inflate with your breath
  • Includes stuff sack and 3M® repair kit

Light but not perfect...

I found this mat to be very light and compact but unfortunately for me my mat punctured on the first night of use. Some how I received a puncture on the underside despite having a footprint beneath my tent floor, no puncture through the tent floor but easily fixed with the repair kit. I was disappointed that due to location of puncture it wasn't covered by warranty. Compared to my old BlackWolf sleep mat it isn't as comfortable or durable but it packs so much smaller. This was originally bought for my partner but she found the BlackWolf more comfortable so I ended up with the StS mat...

Light and easy - with great service

Cracking mat, delivered brilliantly by the Snowys team. Super light mat, packs small and more than comfortable enough. 6 big breaths and it was fully expanded. Recommend the mat and Snowys

So lite!

Fast delivery, best price and great service from Snowys. I love hiking but am not very strong so need to keep my pack light for O/N walks. It's not the most comfortable mat I've ever slept on (though I have slept on heaps worse), but in my opinion, it has the perfect ratio of comfort to weight, when grams are your priority. It is pretty noisy...makes loads of crackling sounds when you move, but it just gave us more laughs than anything else! ps I do intend on inflating it a bit more next time, which might increase comfort even more. Also, a friend suggested slipping it inside my sleeping bag, which might also make for more padding

Quick delivery, product as described.

Haven’t used this in the wild yet, but the mat was delivered quickly and the product is as described on the site. Blows up in a couple of breaths and is very comfortable. Best of all the mat is super light and packs up very small, perfect for hiking.

absolute value for money

so glad I decided to go ahead with this. I bought one for myself and one for my husband. We both could have fit on a regular - my husband is 179cm and he was fine on the regular. Easy to set up, easy to pack up. I've never had such a good night sleep in the bush.

Worth every cent- fantastic!

After previously using low-cost sleeping mats I was sceptical about how much better this one could actually be. Used it for the first time camping in Tasmania; easy to inflate, super supportive, reflects the heat back towards your body, then easy to deflate and roll up. Great product!

Good price and quick delivery

Gave mats as a present. Just been informed “ they are terrific”. Easily blown up. Light and compact.

Broken

I think I may have a faulty mat, when I tried these mats out in store it was quite comfy but when I used my own camping it had half deflated by the morning. Super hard to figure out where the hole is so it's not so useful.

Response from Snowys Dec 21 2017

I'm sorry to hear that Anthea - you're right, something might be a bit skewiff. Would you be able to send us an email (warranty@snowys.com.au) - we'll get straight onto it. Laine

Comfortable

Coming from a foam mat it's not hard to improve the comfort level but this mat ticks all the boxes. Rolls up well, blows up in 7-8 breaths, keeps your hips off the ground even when lying on your side. Everything that was promised it delivered. Great service and fast delivery from Snowys.

I'm 182cms tall. What size Sea Summit Ultralight Insulted mat should I buy? What's your delivery timetable?1 answer

I'm 182cms tall. What size Sea Summit Ultralight Insulted mat should I buy? What's your delivery timetable?

- Balgowlah Sydney(4 weeks ago)

G'day Mark,

I would suggest that you grab a large Sea to Summit Ultralight Insulated Sleeping Mat. The regular is 183cm long but I doubt you'd want to have your head right up the very top of the mat with your feet also at the very end. As for delivery. Provided we have stock when you place your order, it would take us 2-3 business days to get your mat to you.

- Snowys(4 weeks ago)

will the small mat be ok if i just fit on it1 answer

Hi, I'm 168cm tall, so exactly the height of the small matt - would this work and be comfortable or would it be better to go the next size up? I'm wishing they made the small in about 175cm to get the further weight savings because 184 seems overkill. lol. but what can you do?

- Williamstown(1 month ago)

G'day Michelle,

Tough question. When it comes to comfort, you're the best person to determine what works best for you. How do you think you'd go with the mat just fitting you on?

- Snowys(1 month ago)

Two separate inflation channels?1 answer

Does this model have two separate inflation channels, ie a valve on each side near the head end.

- MARLESTON(2 months ago)

G'day Mal, 

Thie Ultralight Insulated Sleeping Mat from Sea to Summit comes with one multi-function valve that has two stages, one for inflation and the other for deflation. Hope this helps Mal!

Are many of your reviews written by the same person?1 answer

Your reviews, especially the 5 star ones seem to written by a small number of people based on writing style. Is that just coincidence?

- Redfern(2 months ago)

G'day Tammy,

Oh really? That's interesting... I honestly couldn't tell you whether it's the same person or not, as all product reviews are written by Snowys customers (& staff) who've given the product a good crack.

On a side note, what sort of similarities do you see? ...because I'm struggling to pick it.

Which size mat?1 answer

Hi team! I'm 166cm tall, what size mat would you recommend? Just want to be sure before I finalise my purchase. Thanks.

- Woodend (4 months ago)

G'day Michelle,

I'm about the same height and I fit on a small, which has the advantage of being lighter. But if you want to be able to really stretch out and keep all of your sleeping bag off the tent floor maybe look at a regular.

More Details of X-Small #21 answer

Apologies - please ignore last email, I now see details I want in drop-downs.

No trouble at all David! I hope you manage to find the perfect mat.

More X-Small Details1 answer

The X-Small is not listed on the STS website, but I note the length from a question previously asked. Could you also tell me the weight of this size, and also the weight of the non-insulated version, please? Thanks.

- Sydney NSW(6 months ago)

G'day David, 

The Sea to Summit Ultralight Insulated Sleeping Mat in the X Small size weighs 0.349 Kg, and the Ultralight Sleeping Mat in the X Small size weighs 0.296 Kg.

You can have a look at the specs of each mat by selecting the size from the drop-down menu - that way you'll be able to compare the whole range David.

Dimensions1 answer

Hi, can you please provide the dimensions of the small and regular. It would be handy if all sizes were shown in the specifications.

- 3280(9 months ago)

G'day Toni,

For next time, as you select each size you're interested in (the drop-down box underneath product title), the dimension specifications will change accordingly.

For the Ultralight Insulated Sleeping Mat the dimensions for the small are 168L x 55W cm and the regular is 183L x 55W cm.

- Snowys(9 months ago)

Hi guys what size mat should I get, I'm159cms tall, thanks1 answer

Looking at the S2S ultralight mat

- Mount Eliza (10 months ago)

G'day Aneeta, 

As your 159cm tall, it looks like the small would be the best length at 168cm long. We are out of stock of this size at this time, so you could very well go for the regular size which is 183cm long which would just give you more wiggle room.

Some hikers do like to go for a size smaller than their height (3/4 length) if they really want to save on space and weight - but the drawback is that your feet can get pretty chilly.

Temperature range?1 answer

Hi there, Just wondering what sort of MINIMUM temperatures this mat would be suited for? Looking at getting a hiking mat mostly for use in Australia, but don't want to have to buy a new one to go to other countries (such as NZ) with. Trying to decide between this UL mat at an R value of 3.3 or the Comfort Light insulated mat with an R value of 4.2 but which is quite heavier and more expensive. Cheers

- Cairns(11 months ago)

Good question Isaac, one for which there isn't a straight forward answer.

R-value is a measure of material to resist the transfer of temperature from one side of a material (in this case a mat) to the other. These values can't be correlated to an exact temperature, and given the testing is done in a lab the results can't be directly transferred to real life scenarios.

As a general rule, for spring/summer camping an R-value of around 3 will be suitable, and for winter camping R-values of 4 and above will be better suited. I'd recommend going for the UL mat with an r-value of 3.3, this way you won't be carrying excess weight on your Aussie adventures.

Then, for colder environments add a basic closed cell foam mat such as this one (although there are cheaper ones around) to your kit and use this underneath your UL mat.

This setup is commonly used my mountaineers as the closed cell mat provides excellent insulation values for its weight and size and add's 1-2 values to the 3.3 R-value of the UL mat, bringing the total R-value up to somewhere between 4 and 5. I hope this helps with your decision.

Weight sustained2 answers

Hello, How much weight does this one can have on top of it without popping ? Regards,

- 3150(1 year ago)

Hi Julian, Sea to Summit haven't listed a specific weight rating for these mats, but they are manufactured to the highest quality and I honestly don't think you could pop one of them if you tried, unless you take a knife to it! I'll get in touch with Sea to Summit on Monday to see if they do have a weight rating and let you know :) 

- Snowys(1 year ago)

G'day Julian, 

I've just been in contact with Sea to Summit, and they've said that the Ultralight Insulated Sleeping Mat doesn't have a weight rating, and as far as they know it would take a significant amount of weight for it to pop - so you shouldn't have that problem unless you laid down on something very sharp. 

- Snowys(1 year ago)

Cold nights1 answer

Would the thermal rating be suitable for an Australian winter maybe down to 0 +/- a few degrees? Or should I look at the comfort plus range or alternate product.

- Queenstown(1 year ago)

G'day Eric,

The Sea to Summit Ultralight Insulated Sleeping Mat is a suitable to use in Australian winters, as it will act as a buffer to stop the transference of temperature. 

If you'd like to have that little bit more cushioning, the Comfort Plus Insulated Sleeping Mat is a good option but it will be slightly heavier and bigger than the Ultralight. 

I think that as long as you choose a mat that is insulated, you should be fine in Australian winter conditions.
