What about the Bestway AlpineLite that's available on Amazon? Weighs roughly the same as the Decathlon and higher R value. As for packed size, I just fold mine so it remains mostly flat and put in my pack.
No, you do not want something like this usually. Although the brand is decathlon, this is essentially the same as an air mattress: its very bulky and heavy. If we stick with Decathlon, the product you want is something like the “Forclaz” line: this is a more common “backpacking” sleeping pad. Its smaller than a water bottle and less than 500 grams. The key takeaway though is this is going to be much narrower than your used to: average camping pad is 20-25 inches wide. https://www.decathlon.com/products/forclaz-mt500-air-mattress-189392?variant=41133720993854
the inflatable one from decathlon is comfortable. i thinks it is the MT500 Air.
A friend of mine has a Exped 5R sleepmat. I can very much recommend it. Good R rating of 5,2 and a dept of 8 CM. It also feels very sturdy and as added bonus it has a inbuilt airpump. The only reason I haven't bought it myself yet is because my current sleepmat (Decathlon Simond MT500) is still good enough.
I did seven months bikepacking and use the decathlon house brand half mattress blow up that’s about the size of a coke can when rolled up with Aussie disposal self inflating as a base that’s the size of a Billy and slept like a log
No this one [https://www.decathlon.com.au/p/inflatable-trekking-mattress-mt500-air-l-180-x-52-cm-1-person-simond-8799965.html?indexName=prod\_pim\_v1\_index&queryID=39bb07b5b0282eb14371b2300bea7500](https://www.decathlon.com.au/p/inflatable-trekking-mattress-mt500-air-l-180-x-52-cm-1-person-simond-8799965.html?indexName=prod_pim_v1_index&queryID=39bb07b5b0282eb14371b2300bea7500)
I quite like the Decathlon MT500 air insulator ones. I started out with the XL size but after a year it developed a leak in a seam. Decathlon replaced it and I accepted the regular sized one in its place as I should have bought that one from the start. R value of 3.3 They are relatively inexpensive. I find them relatively comfortable. As you would expect the regular size one packs smaller and is slightly lighter. Yes the original XL one did develop a leak but, touch wood, it's replacement has been stellar so far. Obviously because of my problems with the last one I'm yet to be 100% convinced about their durability but I've slept on the new one 11 times so far 🤞
