The Comfort PLUS featuring 598 independent air sprung cells, is one of the most sensitive and comfortable sleeping pads available offering an R-Value of 5 which well exceeds the minimum standard of insulation required to be classed as a true 4 season mat.
The Comfort PLUS is formed using dual layer construction - two independent, offset high resolution layers. The higher resolution cell matrices allow greater sensitivity by distributing your body weight and shape over more small cells. The air sprung cells on the top and bottom layers are offset to give more uniform insulation, preventing cold spots.
The mat's firmness can be more finely tuned with dual layer construction - the bottom layer is inflated firm for height, then the top layer inflated to the desired comfort level.
If either layer is punctured, the other layer will provide redundancy, keeping you off the ground and sleeping uninterrupted.
