Our Verdict

Exped’s Dura 8R Sleeping Mats are intended for use in extreme cold environments, being part of the Dura series they are constructed using considerably more durable face fabrics than ultralight models. The top surface is 75denier and the underside is a whopping 170denier, making these mats extremely resistant to puncture and general abrasion, contrast the fabrics with the 20denier top and bottom of the Exped Ultra range.

Comparing the Dura 8R LW with the similarly spec’d Ultra 7R LW, all the specs are the same except for the fabric weight, the Ultra 7R M weighs 865grams and the Dura 8R M weighs 1249grams – it’s nearly 50% heavier.

What we really like about Exped mats are the easy to use non return valves and the superb Schnozzel Pumpsack which makes inflation of the mat simple – its the best inflation sack we’ve used by far and its big enough to act as a rucksack liner or a drybag. In the case of a down filled mat it is essential to use an inflation device as using your mouth forces moisture into the mat which will eventually compromise the down.

The Dura 8R mats are 9cm thick, which is 2cm thicker than a standard mat and delivers an enhanced level of comfort. Unlike the Ultra mats the Duras don’t have the oversized side rails to help you stay on board.

We also need to commend Exped for their environmental approach to the new range – Production is Carbon Neutral (by offsetting), the Face Fabrics are recycled and their factories are Bluesign approved. There is very little packaging and what there is is simply constructed from recycled card.

If you are looking for durability over weight and an ‘Extreme Cold’ mat in a Longer & Wider rectangular format then this mat could be your mat.

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.
