UltraLight SI Mat

Light and packable for minimalist fast hikes, the Ultralight Self-Inflating mats come in at 1 inch thick with the regular size weighing just over 1 pound. We keep the weight down by using a 30-D polyester and our Delta Core-V vertical coring which keeps body contact areas warmer while still offering great support and packability.

Technology

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.
