Sea to Summit Ether Light XT Extreme Cold-Weather Insulated Sleeping Pad, Rectangular - Regular (72 x 25 x 4 inches)

This is a super comfortable mat.It also worked well in the cold (low 40s).Inflating it would invariably take about 5 minutes, and was more of a process than one of the competing mats.

Very comfortable at four inches thick,even though not the warmest and lightest like the thermarest Neo air Xtherm. I was hoping they would have the rectangular version with the temperature rating of the women's version temperature rating, which is a tapered sleeping pad, however the temperature rating of this pad is slightly lower. Not a fan of tapered sleeping pads as they are too narrow and I roll off easily. Another thing I dislike about this pad is that, it is very noisy when you are turning on it. I purchased a sea to summit Aeros Ultralight regular pillow and it is punctured and I used the 3m included patch kit for the sleeping bag to patch it and it still keeps deflating, so that was a waste of $40.00 and it was not the most comfortable pillow,as it keeps sliding around and has no back straps to hold it still in place on the pad. The pillow lock feature on the back of the pillow doesn't work well either, so I will be returning it.

Extremely easy to inflate with the pump sack and packs away quickly. Kept me perfectly warm down to 20 F, I haven't tested the lowest rated temperature.

Only used it one season so far but I camp a lot. Extremely comfy and compact. I highly recommend this product

Needed a sleeping pad for fieldwork in Antarctica so I searched for a good insulation rating. This sleeping pad came with a high R rating, super lightweight and was easy to inflate. The carrying bag turns into an inflation device and makes quick work of the job. No more getting light headed manually blowing air to inflate! I used this sleeping for 30 days of tent camping during the Antarctic summer and it held up wonderfully. Highly suggest for those who enjoy winter adventures!

I gave it four stars because I wish it was a little wider in the elbows. That's my only complaint. It fills up fast with the fill bag they provide and it's easy to roll up afterwards. It's very very warm to the point where I ended up using my sleeping bag as a blanket in 17 degree weather in Montana. It's best if you sleep on your back or your stomach but it still kept me off the ground on my side. It's comfortable aside from my elbows being on the ground.

The pad is perfectly usable, warm, and lightweight. That being said it’s definitely not perfect. The material is more plasticky than my self inflating pad from the same company. The material is much noisier and less comfortable. Even when deflated slightly it still creates pressure spots on my hips and arms (I sleep on my side), this never happened with my self inflating pad. If I deflate it significantly more than my self inflating pad then the pressure spot issue goes away so that’s not the end of the world. The last thing I would like to mention is that it can be a bit too easy to accidentally pull the wrong tab when trying to adjust the amount of air at night -especially if you’re half asleep or not familiar with the pad. The tab for inflating and the one for deflating are both easily accessible at the same time unlike my other pad that requires the inflating valve to be accessed before you can get to the deflating valve. It really sucks to accidentally pull the wrong one and have your pad instantly deflate underneath you :(

Perfect for colder backpacking trips. Nice and sturdy and keeps me much warmer than my old pad. Fills extremely quick with the included bag.

Great little mat - It's light and packs away easily. I particularly like the bag technique as part of the inflation process. I have a long standing shoulder injury and as someone who almost always sleeps on their side - this mat was great for me due to the extra thickness. It's warm and can be easily tailored to an individual level of inflation with an easy to use 'press-function' on the valve itself. It also evens out across mildly uneven ground due to it's thickness. The pillow lock is a nice feature and works with an older STS pillow that I already had. It's quite narrow, but as such fits nicely inside a central sipped bivvi - so you don't slide off the mat during the night. Well thought out, small and lightweight. It will be a permanent feature in my main bag.

What a disappointment. What are all the other reviewers on about? I bought this for my son who complained he was cold overnight. I tried it myself this weekend where it only got down to 2°C and I could feel the cold on shoulders and hips even though they were not touching the floor. This R-rating is nonsense. I have an Exped with similar rating and it is far warmer than this mat. Plus this mat sounds like sleeping on a bag of crisps. It is comfy, but that is it. Not even worth £100. Avoid or stick to summer use. Really annoyed I can't send this back now.

Im Spätherbst bei +5 Grad Tiefsttemperatur draußen übernachtet. Isomatte war warm und auch sehr bequem. Würde ich wieder kaufen.

Dopo aver provato il top decathlon dormendo di lato ho dovuto scegliere un materassino alto per il viaggio a Caponord quindi mi riservo una valutazione definitiva finito il viaggio.Per il momento posso dire che è il più comodo provato anche se un po' rumoroso, mettere sopra e sotto qualcosa tipo asciugamani grandi microfibra aiutano a diminuire il rumore però si dorme quasi come sul materasso.

These look great... ordered yesterday and arrived today, I was told they would take a week. Ordered two, this way I can either make a double bed if camping solo of have the option of an extra bed if camping with a mate.I was expecting them to feel a lot more heavy, but was willing to compromise the weight for a decent night sleep... but they feel alot lighter then I was expecting which is great. The packaging is great too and well protected, compared to other companies then send them out in a fimlsy bag where they can became damaged before you even get to use them, which as been the case in the past.I know they're pricey, but they do feel extremely well made, the material is thick and feels very durable, you can feel the insulation and that there going to be great.I purchased Big Agnes Rapide SL Insulated Double Wide a few months back, only to find that it failed me the first night and ruined my trip... the weight of these two mats combined is less the the Big Agnes double and they don't feel as bulky neither.Highly recommend, I know they cost a lot more then the others on the market... but these feel like there going to last and its worth the investment, plus the R-value is great ... so either way you can use them summer camping or winter camping and your saving money without having to invest in different pads for the two seasons... I guess if your ultralight then these will be heavy, but when compared to other lightweight mats I have, there really doesn't seen to be much difference in the weight or bulk.I personally think your tent and sleeping system makes the biggest difference to your experience, and its worth the investment, rather than buying pads repeatable just to bin a months later because they're not fit for purpose. These feel like there built to last...
