Highly recommended for anyone because it’s long and wide enough to side sleep in the fetal position without your hips falling off pad. Easy to inflate and deflate, small package to carry on a backpack, easy to dust off and clean after sleeping on the ground. It held up to the extremely cold temperature I had to sleep in. I used it with my own extreme cold down sleeping bag and I was very comfortable. I got it on sale, but if I paid full price it’s worth every penny.

Slept in a 0°c bag with a +12°c liner. Night got down to -5°c and was very humid waking up to frost. Was never cold and never touched the ground despite being thin. very comfortable, didn't wake up with my back or hips aching. does squeak but not bad. I've used 2 other brands and although pricy this is amazing quality.

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...

パンパンに空気を入れると若干反発が強いかなぁという感じです。座ると底着きしますが寝ると分散されて安眠できました。ただ高価な値段なのでR値を気にされないならグレード下げてもいいかもしれません。
