Sea To Summit Ultralight Self Inflating Mat

Light and packable for minimalist fast hikes


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.

Key Features:

  • Multi-functional, high flow-rate valve
  • Anti-slip print on base of mat helps hold your mat in place when camping on sloping ground
  • Made from lightweight 30D oikyester 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.
