The Comfort Plus SI series combines the comfort of a 3-inch air mattress with the support and self-inflating performance of a foam core - without the expected weight penalties. This is made possible by our patent pending Delta Core™ technology, which removes the optimal amount of foam without sacrificing support or durability.
A luxurious 30D stretch knit fabric is used on top for a soft next-to-skin feeling.
Lightweight 30D polyester with extrusion laminated TPU is used on the base.
The Comfort Plus SI Mat by Sea to Summit is WINNER of ISPO AWARD 2017 in the outdoor segment.
Utilizes Delta Core™ technology, This removes 40% of the foam horizontally which significantly reduces weight, increases comfort, and reduces the packed size.
Multi-function, patent-pending valve twists over to allow the mat to be rolled tightly without fighting re-inflation as you go.
At 3 inches thick and an equivalent R-Value of 4.1 Click here to learn about R-Values, the Comfort Plus Mat is ideal for comfort-oriented three-season campers.
Luxurious 30D knitted polyester fabric is soft and warm to the touch.
Air Sprung Cells – Small point-weld divided air chambers which individually absorb pressure and conform to the contours and movement of your body without affecting adjacent cells. The result is a mattress that supports you better than one with ‘tubes’ or ‘baffles’.
Liquid-Extruded TPU Lamination Process – An advanced lamination process which ensures an even and durable bond of the TPU (material which makes up the air bladder) to the face fabric. This process is superior to typical ‘roll-to-roll’ lamination and virtually eliminates the risk of delamination.
Multi-Function Valves – Patent-pending, low-profile multi-function valve allows for easy, fast inflation and deflation and enables the user to precisely fine tune the firmness of the mat-tress.
