Forclaz MT500 Folding Foam Sleeping Pad

I used it. it's good

I'm just saying all the ccf pads are essentially the same. Yes the decathlon one is better value than the thermarest or Exped or nemo.

Yep, I use one UK - probably as it wasn't the wisest choice for lightweight insulation on my first ever camping purchase. But it's fine - if bike packing, I use a strip of 3mm closed cell polyethylene foam beneath it (been ok down to c. 2°C with ice on the tent). If thru-hiking, I prefer better insulation of a cutdown z-fold mt500 mat from Decathlon beneath it. Often pitch on brambles, so always want something under the Exped mattress even though it's pretty tough!

I get you, but better to ask, then freezing my ass in 5 °C / 41 °F... + I don't really trust any of thouse reviews... 

I expecting temperatures between 5 °C - 22 °C at night, though they can vary by location and season, with the lowest possible low of 0 °C to 3 °C in Poland (Morskie Oko Lake at ~ 1400 m altitude in mid / late May and the high low of 16 °C to 24 °C in French / Italian Rivieras (sea level) in late June / late July... Yes, probably I'll overheat sometimes in Year 1 in my hammock, but this is easily managed by not using the Top Quilt fully. In Year 2, Year 3 and Year 4 the Top Quilt will be perfect... Taking an 167 g/m² one will be a bad idea because Climashield Apex quilts lose some loft and warmth over time, especially with compression, and one over 200 g/m² will be overkill... 200 g/m² seems like the sweet spot for me... For the cowboy camping part I'm not exactly sure, but I'll pack a lot of wool... whatever will be, will be...  ...

Hitchhiking / Hiking (yeah, backpacking), while sleeping for ~ 6 months in temperatures between 5 °C / 41 °F and 22 °C / 71.6 °F at night, though they can vary by location and season. [OCF Pad](https://hennessyhammock.co.uk/products/4season-explorer-xl-zip) (~ 350 g / 12.34 Oz) + ['MT500](https://www.decathlon.co.uk/p/trekking-folding-foam-mattress-mt500-insulating-195-x-55-cm-1-person/306340/c101m8901525) (480 g / 16.93 oz) = R 3.2 - R 4.2 [for cowboy (stealth) camping]. Buying something like [THIS](https://www.walmart.com/ip/Ozark-Trail-Closed-Cell-Foam-Blue-Camp-Sleeping-Pad/634956813) one (252 g - 320 g / 8.89 oz - 11.29 oz) will save me a few g / oz but is not as durable as the 'MT500 one... NO UNDERQUILT ( it's weighs more then the OCF Pad and I'm too broke to afford one anyway (not a wise choice to buy a cheap chinese one neighter), not a wise choice to change the OCF Pad with a shorter one neither). NO UNDERQUILT PROTECTOR (this does not fix the fundamental issue of compression and lack of insulation). Estimated Usage: Ground System (65% - 75%)... The hammock (25% - 35%) will be my insurance policy for my comfort and my mental health during the wettest, hottest, and most challenging parts of my journey. It is a worthwhile luxury.

Get the Decathlon R2.2 one. It's warmer than a lot of competitors and like 25€. R value is a simple addition, so if you add it to your current pad you'll have a total R value of at least 4.2. Which is pretty good down to freezing and slightly below. Put the foam on top of the airpad (prevents heat loss to the sides). Foam also feels warmer than air.

It's not really open cell. It's CCF but without the shiny plastic coating most of the accordeon styles have. That's why it's a bit lighter compared to competitors even corrected for the slightly shorter length. Here's the [link.](https://www.decathlon.de/p/schaumstoff-isomatte-faltbar-1-person-trekking-mt500-180-55-cm/174619/c149c344m8492712) 370g for 180 x 55 cm. Specs are spot on. It's also somehow gotten cheaper with time, now only 20€ instead of 25€. They also sell a coated [version](https://www.decathlon.de/p/schaumstoff-isomatte-faltbar-isolierend-trekking-mt500-195-55-cm-1-person/306340/c101m8901525) that feels more like a Z-Lite or any of the dozens of copies of that. At a 25% weight penalty, its 480g for 195 x 55cm or 2,5g/cm compared to 2g/cm. Its 5% warmer with a total of 2,2R though. I have used the uncoated version extensively, half of it as a sleeping pad, the rest cut into various backpanels and sitpads, for multiple years in a variety of environments. It's great. Gets the same micro-tears on the surface you'd expect on a Thinlight.

If weight and volume don’t have high priority: Search the plastic recycling bins for packaging foam. Not hard, brittle styrofoam (though that would work as well, but how are you going to transport it?) but the squishy, flexible type you can roll up. Cardboard would work as well if you can transport it and prevent it from getting wet. The cheapest “proper” option is a closed cell foam mat. Instead of going for the well known Therm A Rest Z-Lite you can get the Decathlon clone much cheaper: https://www.decathlon.co.uk/p/trekking-folding-foam-mattress-180-x-55cm-mt500/174619/c149c344m8492712 Insulation between your body and the ground is very important. Ideally for freezing conditions you should have at least 3 or 4cm of foam or other well insulating material (which doesn’t compress too much under body weight) between you and the ground.

Check out the Decathlon foldabletrekking foam pad (https://www.decathlon.ch/en/p/matelas-mousse-de-trekking-pliable-mt500-180-x-55-cm-1-personne/_/R-p-174619). Costs around 20 Bucks, 370 g, R 2.1 ZLite is around 50 bucks, 410 g, R 1.7 So cheaper, lighter and warmer than the ZLite! Slept on it multiple times and was happy with it.
