Exped's Downmat Lite 5 offers a high insulation value with a comfortable airmat construction that's 5cm thick offering a good compromise between warmth, comfort, durability, weight and price.

Exped says: Light in weight: the DownMat Lite offers great performance at an affordable price. Filled with down insulation, comfortable to lie on and compact to stow.    

Includes MiniPump for quick 2 minute inflation, avoiding wetness entering the mat by mouth inflation. Unlike traditional airmats, welded baffles between the down filled chambers eliminate cold spots and create a comfortably supportive and stable air cushion.

Exped's Downmat Lite 5 is a budget model downmat, but actually it's performance characteristics are still pretty good, making it a good choice if you want a comfortable mat that's still pretty warm.

| Oversized side tubes - The side tubes of a downmat are slightly oversize so that the user is cradled in the mat making it less likely that they will roll off.

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.
