We're working out what we think - we'll add our view here!
Inertia pads are engineered exclusively around features that deliver everything you need and nothing you don’t for minimalist backcountry adventures. Each iteration provides support for your head, shoulders, hips, and feet while cutting ounces elsewhere. Unique cutouts in each Inertia pad maximize the loft & warmth of your sleeping bag, similar to our V-Chamber welds in the Static V™ line. The result is an unconventional design perfect for a light, portable, and comfortable sleep experience.
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.
