Product Customer Reviews

👍👍👍👍👍
Nice lightweight piece of gear and very competitive. Good to top up the r value of your sleep system.
Light and comfy. Bought it for cycle touring - and fits nicely on my back pannier rack lengthways, just tucked under the seat.
Does what it states bit big but ok I’m going to be reviewing a lot more camping hiking products on u tube channel unknown camper
Good for sleeping on, better than foam roll mat
Bought this sleeping mat as I forgot mine on a trip and went past a decathlon. Now it's pretty much my main sleeping mat Good weight Comfortable enough (never had a bad nights sleep) Good price
Takes a bit of room when packed and not in use but does the job nicely when sleeping
stops you sliding down the tent, is comfy, and acts as a seat during the day's walking.
As with all folding mattresses it's 'of a size', slightly bigger than the Z-l*te and others, but its made of the same injected moulded foam. The advantage of a folded mattress is you can use it to create a frame in a frameless backpack, cut 3 sections from it to make a kneel/sit pad. It's bullet-proof and will never deflate. You can boot bits out of this and it will still take the lumps out of any surface you care to rest your tired bones on. Its BIG, but reliable...
I have used this and find it farely comftable and it does feel warm. I am a side sleeper this is not really suited to that type of sleeping but use it with another mat so isn't a problem for me and I'm 140kg. Only time will tell if this durable
not had much chance to use too often but impressed so far
It's a standard folding ccf mat, not much to say about it. Comfortable enough and warm enough. I cut mine down to 8 of the 12 sections and it's now 205g. Also useful to act as a frame in my frameless backpack. Would recommend to those looking for a versatile and modular sleeping mat with minimal weight penalty.
Nice
Amazing mattress and very light weight and very comfortable for mountain treks specially in snow trek you have to go for this trust me it's very good product with high quality material used while manufacturing, specially in uneven temperature it is very useful to maintain the body between the ground and the body .....

Additional Product Information
Composition
Foam
- 100% Foamed polyethylen
Volume and dimensions when folded
Folded size 5.9" x 5.5" x 21.7". Elastic support strap. 11.5 liter volume. Weight including the pack: 13.4 oz Foam thickness 65 lbs/m3.
Thermal properties and warmth
Sleep on the aluminized side, facing the sleeping bag with the foam side on the ground to minimize the loss of body heat. R-Value 2.5 (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 the mattress insulates you from the cold ground. An R-Value of 5.9 means a minimum temperature of use of approximately -11°F. 0.7 is equivalent to a temperature rating of +52°F.
Thermal properties and warmth (2)
The R-Value is not a standard, each manufacturer can use their own criteria. A standardization process is currently underway.
Comfortable postural support
For a foam mattress, this mattress offers a greater level of comfort thanks to its design and the depth given to the foam by the mold. This specific design allows for 0.8" mattress thickness, giving home comfort and real postural support.
