High-end entry-level mat in 3D construction
Exped says:
DeepSleep Mat provides an eco-friendly blend of support, warmth, and durability. It’s low profile and generous sleeping surface cater to those who prioritize value without sacrificing comfort.
With 3 inches of solid foam, DeepSleep provides a high level of insulation against the cold ground and provides a more firm sleep surface. Dial in your exact firmness further by using the included Top-Up Pump to add more air or by opening the valve to purge excess air.
PRO TIP:
It may sound counterintuitive, but if you find that your camping mat is just a little too hard, use the inflate valve to purge excess air. By opening the valve and pressing gently on the one-way flapper, you can release controlled bursts of air to reach the exact firmness you want. If you open the extra-large deflate valve, you may find yourself losing more air than you anticipated and need to top off your mat again.
Inflation: For first time use allow the mat to partially self inflate by opening the inflation valve and inserting the toggle attached to the inflation valve cap. Leave mat for at least 1 hour, then inflate completely by using an EXPED pump and close inflation valve. Now leave the mat for 24 hours in a warm environment to allow the inner foam layer to recover to its full volume.
In normal use, once in camp, unroll the mat, then open the inflation valve. To speed up inflation of the mat, insert the toggle attached to the valve cap into the inflation valve.
After being stored for a long time, use same procedure as for first time use.

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.
