All about this product



The Ultralight Insulated Sleeping Mat from Sea To Summit features a single layer construction throughout for maximum comfort and insulation with minimum weight.


The air sprung cells are the core technology of this mat and are the reason why you will sleep better when exploring the outdoors. Instead of the typical baffled construction, Sea to Summit sleeping mats are constructed using a dot-weld pattern to create a high surface-area matrix of interconnected chambers called Air Sprung Cells. These operate in the same way as a pocket spring mattress; as each cell deforms independently, the mattress conforms to your body shape which feels softer and more comfortable with more body contact area.


Exkin Platinum thermal technology reflects radiant heat loss back to you, while the Thermolite insulation lofts up inside the Air Sprung Cells to prevent convective heat loss from your warm body to the cold ground. The Exkin Platinum and Thermolite technologies are combined in this mat to ensure you stay as warm as possible while carrying the lightest weight.
