G'day Charlie,

Limited Lifetime warranties don't have a defined period of time.  It comes down to the perceived life of the product in conjunction with usage.  This may be a completely different period of time for one person than another, eg. you've had it for 18 months but absolutely thrashed it on weekly adventures versus someone who had it for 4 years and used it a handful of times.  The lifetime of that product is reasonably different in both cases. Hope that makes sense!
Generally Limited Lifetime warranties are designed to give the consumer more long-term protection that far exceeds the standard required period.
If you want more information, head to Sea to Summits warranty info page.

G'day Laura,

The Ultralight Insulated Mats can be stored in their storage sack, they're a little different to a self-inflating mat, which we'd suggest storing flat if you can. As with most high-end gear, if you can store it somewhere where it will remain clean, dry and at a relatively stable temperature that will be best.

G'day Kate,

Yes, this will be fine for all climates and temperatures. It's best to think about your mattress as part of a sleep system where the sleeping bag, liner - cotton/silk or synthetic/fleece and mattress all work together to help keep you comfortable. Then you can fine-tune this with clothing/thermals etc. Hope this helps!

G'day Ben,

The Ultralight Insulated Sleeping Mat - Large will fit comfortably in the Nomad 2. You should also be able to fit your pack in the tent but as you've said it will be a bit of a tight squeeze.

G'day Rohan,

The felt stickers should be included with your mat. Basically peel off the back of the sticker and attach it to the marked area on the mat.  You should then be able to use the pillow lock system with your pillow. Send us an email with photos so we can see what you've got if you need more clarification or if something seems to be missing.

G'day Cathy,

The external dimensions are based on inflated size, these mats decrease in size (mainly length) a fair amount once inflated. Generally, the S will designate the size, but I'm happy to double-check for you if you ordered the previous mat from us I can search our system and check, or if you email through a photo of the labelling I should be able to find out for you.

G'day Alana,

As a general rule, for spring/summer camping an R-value of around 3 will be suitable, and for winter camping or colder adventures aim for a minimum of 4.

I'd recommend checking out the Sea to Summit womens specific sleeping mats, as they have extra insulation in all the right places, and a slightly higher R-Value than the unisex equivalents.  Based on the -5 temp, I would suggest looking at the Comfort Light Insulated - Womens...its a bit thicker, much warmer, and only around 100g heavier.

G'day Glen,

I've just double checked and our new stock of the Ultralight Insulated Sleeping Mat & Pump comes with the pillow lock system. You just have to adhere some small felt type pieces to the mat when it arrives to be able to use the system. 

G'day Aaron,

Thanks for your enquiry. The Sea to Summit Ultralight Insulated Sleeping Mat & Pump is a great choice for a comfortable and lightweight hike mat. The only note I have is the mat is only 1cm longer than your height so you're only just going to fit on the Large lengthways. Sea to Summit also makes the Comfort Light Sleeping Mat & Pump. The length of the large is a bit longer at 201cm so that may be a bit more comfortable and still very lightweight. The only other option I can think of in the Sea to Summit range is the Sea to Summit Camp Mat Self Inflating Sleeping Mat. It's 210cm in length but a little bit heavier at 1.180kg. 

G'day Eric,

How full you'd inflate the Sea to Summit Ultralight Insulated Sleeping Mat is pretty much up to you. I'd be wary of inflating it too much but whatever you're most comfortable with, go for it! As for packing it up, we'd recommend rolling it, don't stuff it back in the sack as it probably isn't the best for it. 

G'day Kev,

I reckon the Sea to Summit Coolmax Fitted Sheet will be a winner for your Sea to Summit Ultralight Insulated Sleeping Mat. 

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.

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?

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! 

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.

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. 

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

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.

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.

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. 

G'day Alice, 

The external dimensions of the Ultralight Insulated Sleeping Mat in X-Small are 128L x 55W cm and the packed dimensions are 23L x 9W x 9H cm.

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.

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 :) 

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. 

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.
