If you're looking for the best value for your money, I can highly recommend the Forclaz MT500 Air L from Decathlon. I personally own several high-end sleeping pads and can make a direct comparison. And honestly, for the average summer camper, the more expensive models don't justify the price.

I'm a side sleeper and I'm absolutely fine with it, thanks to its 7 cm thickness and stable design. However, the 52 cm width of the L version might feel a bit narrow if you have broad shoulders or tend to move around during sleep. For extra comfort, you might want to consider the XL version with 65 cm width.

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

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 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'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.

I used to sleep on [this](https://www.decathlon.co.uk/p/inflatable-trekking-mattress-size-l-mt500-180-x-52-cm/189392/c344c344m8799965) mattress from decathlon. Used it for an one year journey from Europe to Kyrgyzstan. I loved the mattress, slept well, no punctures and you could fold it very small. The thing is, when the temperatures dropped, the mattress is not so suitable anymore. I learned to look at the R-value of the mattresses. If you go to sleep below 5 decrees celsius, I would at least look for an R-value above 3.0. I recently bought the [Rab ultrasphere 1.5](https://rab.equipment/eu/ultrasphere-1-5-sleep-mat?queryID=7c0e8b4d59e9a38c4bfad331f687a7b4&objectID=63330&indexName=rab_live_eu_products&_gl=1*1hjlxj8*_up*MQ) . I am still using the mattress from the decathlon in summer, but I will this mattress in the wintertime. The [decathlon version with higher R-value](https://www.decathlon.co.uk/p/lightweight-inflatable-trekking-mattress-size-l-mt500-l-180-x-52-cm/311475/c242m8853280) was not an option, because it was packed way to big. So, check the R-value if you go in warmer conditions, and also check the size of mattress unpacked. Good luck!

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.
