Exped's AirMat UL Lite sleeping mats are among the lightest available and have one of the smallest packed sizes, with no additional insulation it's still good down to 5C.

Exped says: The lightest, warmest and most comfortable sleeping mat in its category - and super packable! Next-to-skin comfort and anti-slip GripSkin honeycomb-pattern coating. Laminate is air tight and impervious to hydrolysis.

Sleeping mats are about comfort and insulation, airbeds are easily the most comfortable of all the mat types and most have a degree of insulation built in, the lightest however don't have any insulation as this adds weight - Exped's AirMat UL Lite Sleeping Mat is among the lightest and despite having no added insulation it ticks the boxes in all other respects.

Weight and pack size are extremely good, the Airmat HL is 5cm thick so it will not match the comfort of most of the Exped range since comfort is a function of thickness for airbeds. Its a rectangular mat - the very lightest mats are usually mummy shaped to save weight but many people prefer rectangular mats because they are easier to stay on - which is why Exped have provided this option while making all the other lightweight cues.

A further weight saving over other mats in the Exped range is made by using a single valve for inflation and deflation (Exped pioneered the two valve system).

Because of the relatively low insulation value Exped rate this mat for use down to 5C, but that's quite cold and covers a wide range of conditions, if you do most of your backpacking in the summer this could be the best option. Even for occasional use in colder weather you could team it up with a closed cell foam mat to boost the insulation value.

Exped Mini Pump included.

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.
