Technical Information

Volume and folded dimensions
Rolled dimensions Ø 13 x 50 cm. Volume 6.6 Litres. Density of the foam 30kg/m3.
Thermal insulation and warmth
Sleep on the aluminised side, facing the sleeping bag with the foam side on the ground to minimise losses of body heat. R-Value 1.2 (measured by EMPA, an independent laboratory). The R-Value is a measure of the thermal performance and insulation. The higher the R-Value, the more your mattress will insulate you from the ground. An R-Value of 5.9 is equivalent to a minimum temperature rating of about -24°C. 0.7 is equivalent to a temperature rating of +11°C. The R-Value is not a standard.

Camping mat
Used for 3 to 6 months
Used outdoors on grass. Comfortable. No princess and the pea type complaints.
Used for 2 to 8 weeks
Good and comfortable but width should more at least 6 inch more for better .
As a low cost mat, this serves it purpose
This is a great alternative to sleeping pads . It is lightweight and acts as a mildly insulating layer from the ground (i'm not sure it has an R-value). I would recommend this for use during the summer and milder winter months.
Good value
Used for 2 to 8 weeks
Lightweight and good value for money. Like the piece of elastic that comes with it to keep it rolled up. A good touch. Bought the thinner mat as lighter but still reasonably comfortable. Perfect for my son's DofE.
Sleep tight
Used for 2 to 8 weeks
This is good for its lightweight carry on
M100 Foam trekking matteress
Used for 1 week or less
We bought these for my husband and son as they were going on a camping trip. They both found them very uncomfortable to lay on. We did wish we had bought an inflatable mattress which is what we will be doing for future camping trips.
M100 Foam trekking matt review
Used for 2 to 8 weeks
You might as well just sleep on the floor with nothing else, this made no difference whatsoever whilst waking up with aches all over me
Good, used it for the Reading festival
Used for 1 week or less
Light, compact and unexpectedly durable!!
Used for 1 week or less
I highly recommend this sleeping pad even for colder night outdoors.
First of all, it was delivered after only 3 work days and I live in Iloilo. It was not bubblewrapped, which is to be expected, but I was still surprised to see that they boxed it. It was wrapped with 2 garters so it stays rolled up.
Furthermore, I like that is was just the right size for me {i'm 5'8"}.
I bought it with me to mt. Lingguhob last week and it performed phenomenal . It was rainy, so the camp site was damp and colder than usual, but this bad boy held its ground. It provided me warmth, kept me dry and it felt thick considering this is one of the thinner kinds on the market. Obviously, it's also lightweight and packed nicely on my hiking bag.
Finally, for a sleeping bag wiyh such specs, insolation and a price tag of only a third compared to those high end brands, this guy definitely steps up. I would surely recommend this to friends. Kudos!
Used for 2 to 8 weeks
This is a very good quality roll up mattress for camping, sunbathing or staying with is so reasonable in price too.
