Still the most economical warm-weather pad available, now completely redesigned from the inside out and R-Value rated by a third party. The adventure-ready Air Core Ultra is a smooth and stable sleeping surface for wherever you setup camp. With an easy and fast inflate/deflate valve, tough exterior nylon shell, this pad is light and packable. Save your breath for hauling the rest of your gear and use the included upcycled pad inflation sack to inflate.

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.
