Forclaz MT500 Air Sleeping Pad

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.

I'm still loving my Decathlon MT500 Air - it's not insulated, but I slept on it down to freezing temperatures, though that wasn't really that nice. The normal one is about 50€ and weighs 500g, they have an insulated version for 80€ now, but that one is heavier of course. As for a sleeping bag, below 100€ is hard unless you don't expect nights below 10°C.

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.
