The lightweight, compact Big Agnes Air Core Ultra inflatable sleeping pad is ideal for backpacking. Designed primarily for summer or warm-weather use, the pad packs down small and takes up very little space in your backpack.

Durable I-beam construction provides stability while reducing weight and bulk. The outer chambers of the Air Core Ultra are bigger than in the original Air Core, which will keep you cradled in the middle so you don't roll off in the night. All the latest pads from Big Agnes have received an updated air valve for easy one-way inflation and convenient, super-fast deflation.

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.

Very good choice

I am a side sleeper so I wanted a more comfortable mat than the one I tried in May (from a big blue french brand). After research, I ordered this Big Agnes mat for the very good price/quality. Very easy to inflate and deflate. More lightweight than described: 480g (17oz) with the bag, I am very satisfied. Just some info to future buyers: mine was shipped from Big Agnes warehouse as it was mentioned and after transit in The Netherlands, I received it after four weeks.
