Featuring a dual-layer zoned construction, the Sea To Summit Comfort Light Insulated Sleeping Mat not only looks awesome, but it also provides great comfort and warmth in a lightweight trekking and hiking mat.
Air-filled cells function in a similar manner to a pocket spring mattress with single-layer cells in the head and feet areas and dual layers in the torso to create a mat with an outstanding balance between comfort and weight.
Thermolite® fill and silver-coated Exkin® Platinum fabric both insulate and reflect heat back to your core. When combined with the comfort of body-conforming air cells, prepare for daily sleep-ins… and with that, an impatient trekking party!

Fitted sheet to reduce noise1 answer
Hi Legends, I'm considering one of these but am a light sleeper and concerned about noise. Wondering of some form of fitted sheet would reduce this, have you heard of this working? Thanks, Ben
Ben - Wangaratta, VIC (4 weeks ago)
G'day Ben,
Yep, for sure - the noise is usually dependant on the type of sleeping bag you have, and seems very much down to individual interpretations on "noisy". We recommend sliding you mat into a liner for this reason, Sea to Summit used to do a fitted sheet but it's not available anymore.

So a stuff sack?1 answer
Dows this mean it can be stuffed back into the bag or folded and rolled?
Geoff - Terang, VIC(1 year ago)
G'day Geoff,
The mat needs to be folded and rolled, unlike a sleeping bag, mats generally cant be stuffed.

R value1 answer
Do you know if the R value of the current model of the Comfort Light is the same as one purchased in 2017?
GG - East Melbourne, VIC(3 years ago)
G'day GG,
Sea to Summit have made a few minor changes to these mats since 2017, including a slight colour change, the inclusion of a pump sack, and the new pillow lock system to hold Sea to Summit pillows in place at the head end of the mat. In terms of R-value, they've indicated that they've not made changes to the insulation of the mats, but due to the change in testing protocols, some models of the mats have had an increase, while other models have had a decrease in R-value.

Insulation if deflated1 answer
If this mat gets punctured and deflates during the night, does it still provide any insulation? Thanks.
Ali - Bayswater (4 years ago)
G'day Ali,
It will add some insulation value as there is thermolite filling in the air cells, however if the mat isn't inflated, then it won't provide any comfort, and very minimal insulation value. Luckily this mat has dual air cell layers, so it would be pretty unlucky if you managed to puncture through both layers. They do also come with a puncture kit that is pretty easy to use, incase you needed to do a late-night repair.

What to pair with the mat?1 answer
I’m upgrading my hiking sleep set up and wondering what lightweight sleeping bag you would recommend to go with the mat? I am 174cm tall and need something that can work between -5degrees to 28 degrees.
Nina - Melbourne(5 years ago)
G'day Nina,
I can absolutely help you out! The Comfort Light Insulated mat is a great option, the regular length will suit your height. In terms of a bag, you could go for one of the unisex models regular length or a women's model in long length. I would probably suggest checking out the Sea to Summit Trek Tk3, Journey Jo2, Ascent Ac2 or Altitude At1, and the Marmot Sawtooth or Angel Fire. It might be best to give us a call and we can chat about your main needs and the type of hiking you do and get you lined up with a great system.

Warranty 1 answer
Hi,
In the description it says limited lifetime warranty. Can you explain what this means?
what is the most comfortable of hte sleeping mats1 answer
im looking at the sea to summit range there is a green one and 2 red ones all under 1kg in weight , which is best
mellisa - cairns qld(6 years ago)
G'day Mellisa,
Thanks for your enquiry. Sea to Summit colour code their mats according to the R-Value (insulation) and mat thickness of each mat. Red mats tend to be thicker and provide more insulation so the red comfort plus insulated sleeping mat and the red comfort plus SI sleeping mat are the more luxurious and generally more comfortable of the hike mats but they are also heavier than the green comfort light insulated sleeping mat. If the weight of the mat is particularly important, the green comfort light may be the one to go for at only 620 grams. I hope this helps.

Side sleeper1 answer
Is this mat comfortable enough for a side sleeper with bony hips? or is the STS Comfort Plus Insulated mat a better option?
Durga - 7249(6 years ago)
G'day Durga,
The Comfort Light Insulated Sleeping Mat should be comfortable for a side sleeper as there is a dual air cell layer from shoulder to hip that will keep you nice and comfy. The Comfort Plus Insulated is a dual layer down the whole mat, so if you wanted to make double sure your knees are ok you could go for that model.
Leece - Snowys(6 years ago)
What is the width at the tapered end (the foot end)?1 answer
The listed width says 55cm, but I assume that's at the widest part at the head end
Cameron - Canberra(6 years ago)
G'day Cameron,
I've just given the Large (our display model) Sea to Summit Comfort Light Insulated Sleeping Mat the once over with my measuring tape. It was about 64cm at the widest point on the shoulders and was about 40cm where you'd put your feet. With the regular, I'd say it would be about the 35cm mark but it does taper all the way off to nothing at the bottom so it does depend on where you take the measurement from.

Regular size back in stock?1 answer
Are you expecting more stock in the Regular size soon?

We are expecting them in soon, so we've changed the ETA on the product page to reflect the latest information. Hope this helps Roger!

Is the noise still an issue with these Sleeping Mats4 answers
Is the noise still an issue when you turn over when sleeping on these Sleeping Mats. A lot has been said about it in the reviews?
Rob - Cromer NSW(7 years ago)
G'day Rob,
The ripstop nylon that the Sea to Summit Comfort Light Insulated Sleeping Mats are made from makes for a really durable mat. The side effect, however, is that they do tend to be a bit crunchy in sound when you roll over on them. If you're a deep enough sleeper, you won't notice this at all but if you're prone to waking at the slightest sound, then maybe this mat isn't the ideal one for you.
Ben - Snowys(7 years ago)
Hello, Ben thanks for the quick reply. Yes, unfortuantley I am a light sleeper!! What do you suggest for another oiption? Doing Kokoda this April need something fairly lightweight but comfortable?
Rob - Cromer NSW(7 years ago)
G'day Rob,
You'll be sacrificing a little bit of weight but I reckon you would probably be best looking at one of the Sea to Summit Self Inflating Mats. They'll be a lot quieter for you whilst you you're sleeping.
Ben - Snowys(7 years ago)
While doing the overland track some fellow travellers had these mats (as we did also) and advised putting it in your silk/ cotton sleep sack radically reduced the chip packet crinkle sound. We've the same mats and carry a second lite weight sack. The noise is no longer a problem we are very happy with the thermal rating comfort.

R Value per seasons1 answer
I was wondering if this mat would be recommended for only winter months ? Due to the R rating value.
Ben - Chatswood(7 years ago)
G'day Ben,
R-Value represents the resistance to the temperature which makes it valuable both in winter and summer months as it 'resists' the warmth and cold coming from the ground. As such, the Sea to Summit mats, depending on the environment being used in, are very effective in both summer and winter months.
Summer warmth typically doesn't require as much resistance as winter cold does, which makes considering the R-Value for winter months more beneficial.

packed size1 answer
Does this pack down significantly smaller than the standard insulated comfort plus (small)? I have looked online at the dimensions of all the mats but don't think it is terribly accurate. I own the STS Ultralight insulated in large (hubbys mat) and I have the Comfort Plus Insulated (small). I think my mat is just a tad on the bulky size so was looking to save a bit of space in my pack, without compromising on my comfort too much. Thoughts?
JC - NSW(7 years ago)
G'day JC,
I like you're thinking, but ultimately, only you can decide if it's worthwhile to downsize from the Comfort Plus to the Comfort Light. As you say, you'll save a little bit of space and weight, while also compromising on comfort.
I've just gone and doubled check some of the measurements and they all appear to be correct. Some may be half a cm bigger than listed but this is all dependant on how people roll them up etc.
I'm not sure if you're aware, but as you select different sizes on the right-hand side below the product name, the dimensions will change to suit the size.
Ben - Snowys(7 years ago)
Does the large size fit into the jet stream?1 answer
To keep weight and packing sizes down I was thinking of just using the pump sac but I'mm not sure if the large size will fit into the jet stream.
Stewart - Melbourne(7 years ago)
This is a good question Stewart, and not one that seems to have been addressed anywhere previously.
Just looking at the packed products alongside the Jetstream Pumpsack, the mats that would appear to fit comfortably are the non-insulated Comfort Light and the Ultralight range of mats in all sizes. The XS Ultralight insulated may fit at a squeeze, but any the other mats, particularly the insulated models will probably be a hassle to squeeze into this pumpsack. I hope this is useful.
Ben - Snowys(7 years ago)
I'm 163cm tall, so size wise1 answer
will the small at 168cm be OK or should I opt for the regular size mat?
Sue - Ashburton(7 years ago)
G'day Sue,
For your height, it looks like the small is going to be the better fit. You could go for the regular size if you prefer a more spacious mat - it's really up to you as to what you'd be most comfortable with, and if you don't mind carrying the extra little bit of weight and volume.
Emily - Snowys(7 years ago)
What is the size of the small mat?1 answer
I am 161cm tall. I was thinking about the regular for extra comfort, but just want to check. Thanks
Rikeesha - Perth(7 years ago)
G'day Rikeesha,
The length of the Comfort Light Insulated Small Mat is 168cm making it a perfect fit for you. In comparing the small and regular sizes, there is no difference in thickness, so there is unlikely to be any difference in comfort.
Ben - Snowys(7 years ago)
Do I need a pump for this mat? And what size should I get if I'm 159cms tall?1 answer
Comfort light insulated may
Aneeta - Mount Eliza (7 years ago)
G’day Aneeta,
You can actually inflate this mat with your breath, but we would recommend that you pick up either the Jet Stream Pump Sack, or the Air Stream Dry Sack which will make inflation so much easier.
Most hikers try to save on as much weight and space as possible, but I would probably recommend going for the small size which is 168cm, that way your feet won’t dangle over the edge of the mat and leave you cold.

How do you choose a size for these mats?1 answer
how do you chose a size for this brand?
I'm 173cm tale.....
Daniel - NORTHCOTE(8 years ago)
G'day Daniel,Â
On the product page where it says 'Choose from 3 sizes', select the arrow drop down, and you'll be able to choose from small, regular or large.
As you're 173cm tall I would choose from the regular size (184cm long) and the large (201cm long) depending on what length you would prefer.Â
Emily - Snowys(8 years ago)
Could you please explain R value?1 answer
David - LARGS NORTH, SA(9 years ago)
R Value is a measure of thermal resistance David, or in simpler terms a measure of how well the material resists cold or heat transferring from one side to another. It is the same measure used for the insulation in the ceiling of your home, the higher the R-Value the better the ability to retain or maintain temperature.
