Great Folding Mat/Pad

Easy to use and transport. Doubled as a seat cushion on long hikes, but used mainly as a Sleeping Mat under my Sleeping Pad. Did an excellent job on my back country camping trips in Ontario.

Wish I'd found it sooner

OK I've literally just had it but have tested it on loads of bags of frozen veg. I've had tons of foam mats, military, nemo, multimat, exped to name a few and can already tell this is going to be my go to mat. It's one of the warmest, comfy, slightly wider without being ott and I prefer the folded dimensions and colour. Exceptional value and brilliant service from this site. Thank You guys.

Good buy

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

Big but comfortable

Takes a bit of room when packed and not in use but does the job nicely when sleeping

What is the r-value?

The R-Value is a measure of the thermal insulation. It measures the ability of a mattress to retain or prevent heat from escaping from a warm body (human body) to a cold floor.The higher the R-Value, the better the insulation of the mattress.Please note that the R-Values can be added; this means that you can use two mattresses and add their R-Values.All our mattresses are tested to standard ASTM F3340-18.

What r-value for what use?

R-value from 0 to 1.9: Hot season (summer) onlyR-value from 2 to 3: 2 or 3-season (spring-summer-autumn)R-value from 3 to 4: 4-seasonR-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)

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 mould. This specific design allows for 2 cm mattress thickness, giving home comfort and real postural support.
