Lightweight, inflatable trekking mattress MT500 L

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 🤞

I use this for bikepacking: [https://www.decathlon.co.uk/p/lightweight-inflatable-trekking-mattress-size-l-mt500-l-180-x-52-cm/311475/c242m8853280](https://www.decathlon.co.uk/p/lightweight-inflatable-trekking-mattress-size-l-mt500-l-180-x-52-cm/311475/c242m8853280) It is lighter 620g and the pack size is actually smaller than what Decathlon states, at about 2 l. The stuff bag doubles as the inflation bag. It is, for me much more comfortable than a self inflating matt and the R value of 3.3 is quite good. Edit, I'm a side sleeper too.

I have the Decathlon MT900 sleeping bag 0°C (down). Overall quite happy with it, I am cold sleeper and was comfortable at temperatures around 5°C without wearing a puffy, jumper or beanie. Build quality seems solid, haven't had any issues with it. My pad is the Simond (used to be Forcalz IIRC) MT500 Air isolated size L. Although I wasn't sure at first if the tube construction would be comfortable, but after using it I have no complains. Not the lightest or highest R value but overall I am happy with it, definitely considering the price. Decathlon seems to have a 20% discount on the MT900 sleeping bag Minimal Edition(undyed), lowering the price to 160 euro. Might be interesting if you can live with the white color.

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.
