Sea to Summit Comfort Light S.I. Matto Regular, green
The Comfort Light Self Inflating Mat is an excellent lightweight, backpacking option that offers suberb comfort with minimal weight and packed size. The Delta Core technology removes 40% of bulk and weight while leaving a 2 inch thickness to keep your nights comfortable. The multi-function valve is a low profile, high volume valve that allows fast deflation without fighting re-inflation as you go. The self inflating mats join the award winning Air Sprung Cell mats to comprehensively round out the sleeping mat range - everyone is covered.
Delta Core Technology 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.
