ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.

Not really a proper sleeping mat

Perhaps a closed cell foam mat is nice if you're having a meal outside and don't want your clothes to get wet or dirty... but it does not qualify as a sleeping mat in my opinion. I spent one night on this one and tossed it into the bin the next day... I could have just as well slept on the ground to be honest. What makes it even worse is that it's not even small and compact when folded together either, thus absolutely not ideal for backpackers if you ask me (and I have a 70 litre hiking backpack). Investing a bit more money into a self inflating mat or air bed is definitely a must in my opinion if you don't want to have a sore back the next day... sorry, but I can't recommend one of these.
