The Sea to Summit Comfort Light SL 170x53cm sleeping mat impresses with the specially developed Delta Core technology in the Comfort Light SI is an innovative approach to reducing the weight and mass of the polyurethane foam core of the self-inflating sleeping mat.
The manufacturing process for punching out the Delta Cores reduces the original volume of the PU foam by 40% and makes it possible to minimize the weight and pack size of the sleeping mat as much as possible.
Another advantage of this technology is that the upper and lower connection between the outer material and the PU foam is glued completely seamlessly.
This ensures even thermal insulation along the entire length of the sleeping mat, avoiding cold bridges and reducing the risk of delamination.
