Sea to Summit Comfort Light Self Inflating Mat is using our Delta Core™ technology and it is for those of us who are looking for the perfect compromise between comfort and weight in a traditional self-inflating foam mat.
At 5 cm thick, you can be sure of a great nights sleep while an R-value of 2.7 will give you plenty of insulation for 3-season comfort and still leave you with plenty of room in your pack for everything else.
All of our S.I. mats use the first ever, multi-function single valve designed specifically for self-inflating mats. No more fighting re-inflation as you try to roll up your mat!

What is Delta Core Technology?
Sea To Summit Delta Core technique is a truly innovative approach to reducing the weight and bulk of the polyerthane (PU) foam core of our Self-Inflating mattresses. Our patent pending coring process removes up to 40% of the initial volume of the PU foam, retaining enough for optimal support and comfort, while minimising the packed weight and size of the final mattress. 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 mattress, avoiding the vertical holes or frame-like gaps that have traditionally allowed warmth to leach downwards. The full foam surface also provides significantly improved bonding of the foam to the shell fabrics of the mattress, thereby greatly reducing the chance of delamination. The shape and size of the Delta Cores are adjusted across the different thicknesses of our mattresses to ensure strength and durability, while still giving the user excellent support and self-inflating performance. The horizontal Delta Coring technique is used in our Comfort Light SI, Comfort Plus SI and Comfort Deluxe SI models.
What is 30D Polyester TPU?
The 30D polyester is a lightweight woven fabric with an extrusion TPU lamination and is used in our Self Inflating mats. The TPU lamination makes the fabric airtight and allows the PU foam inside our self inflating mats to be bonded to it.
