Sea to Summit Comfort Light Insulated Sleeping Mat

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.

G'day Geoff,

The mat needs to be folded and rolled, unlike a sleeping bag, mats generally cant be stuffed.

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.

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.

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.

G'day Matt,

Sea to Summit explain their Warranty and Lifetime Guarantee in detail on their website.  Click through and have a read for the full explanation.  Hope that helps mate :)  

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. 

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.

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. 

G'day Roger, 

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! 

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. 

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. 

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.

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.

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.

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. 

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.

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. 

G'day Daniel, 

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. 

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.
