Comfort Light SI Mat

The Comfort Light SI series aims to hit that sweet spot of minimal weight and packed size but also offers great comfort. At 2 inches, this mattress is going to protect you from just about any less-than-perfectly flat terrain.

Our Delta Core technology makes sure that the additional thickness doesn't equate to an increase in weight and provides even insulation across the length of the mattress. The Comfort Light series is made from lightweight 30D polyester with extrusion laminated TPU.

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.
