Sea to Summit Comfort Deluxe Self Inflating Mat Double blue

The height of camping luxury has been realized with this plush 4-inch thick sleeping mat that truly epitomizes camping comfort. The internal foam "walls" add comfort at low pressures and temperatures, and the multi-function valve makes deflation as easy as can be when you're ready to pack up and go. A luxurious, soft knit face fabric affords sleepers the luxury of comfortably slumbering directly on the mat.

Delta Core
Delta Core process uses large horizontal triangular cores to remove 40% of the mat’s PU foam weight and bulk. This patent-pending technique is a truly innovative approach to producing a minimal packed size and weight mat while maximizing comfort and thickness. Importantly, this coring technique has the additional benefit of keeping the top and bottom surface of the PU foam completely intact. This ensures consistent warmth along the full length of the mat, avoiding the vertical holes or frame-like gaps that have traditionally allowed warmth to leach downwards and away from the body. The intact foam surface also provides significantly improved bonding of the foam to the mat shell fabrics, which greatly reduces the chance of delamination. The shape and size of the Delta Cores are adjusted across the different thicknesses of our mats to ensure strength and durability, while still giving you support and self-inflating performance. The horizontal Delta Core technique is used in our Comfort Light SI, Comfort Plus SI and Comfort Deluxe SI models.

Multifunctional, high flow-rate valve
For easy inflation, one-way deflation (ensures that the mat cannot refill itself while being rolled up) and fine tuning for comfort.
