Exped says:
The Flex 1.5 is an extremely light, robust, and versatile closed-cell foam mat for trekking, bikepacking, or camping. It is suitable as a stand-alone mat for 3-season use or as an additional layer of insulation and protection under an inflatable mat.
The R-value of 1.5 provides reliable basic insulation and at the same time protects against sharp surfaces. The foldable construction enables quick deployment. The high-quality, environmentally friendly IXPE foam is particularly durable, water-resistant and dimensionally stable.

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.
