Sea to Summit says
Featuring a women's specific shape that is wider at the hip and narrower at the shoulder, Exkin Platinum® and a thicker THERMOLITE® insulative layer are combined with a hybrid dual-layer of medium resolution Air Sprung Cells™ in the torso for increased comfort, and a single layer in the head and leg area for a small packed size.
The Comfort Light sleeping mats feature hybrid layer Air Sprung Cell™ technology - a double layer of high resolution cells in the torso for maximum comfort and insulation, and single layer of medium resolution cells in the head and legs for reduced weight. We use Exkin® Platinum, a quiet non-woven fabric, to reflect radiant heat loss back to the user and Thermolite® insulation to prevent convective heat loss between your body and the ground.
Our Verdict
Sea to Summit's Comfort Light Insulated Sleeping Mats are some of the most technilogically advanced sleeping mats that we stock. Air sprung cells that mimic your mattress at home provide extreme comfort. This feels all the better when you realise that you're only carrying something that weighs 600 grams.
The integrated insulation means you are going to be able to use this mat across the year in the UK, you might need to beef it up in the dead of winter but other than that you'll be ready for anything the UK can throw at you.
The free pumpsack is always a blessing and you will inflate your mat in no time at all once you master the art of pumpsacking.

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.
