UltraLight Insul Mat


Product Sizes


The Ultralight sleeping mat range has a single layer of medium resolution Air Sprung Cells™ to give you the lightest and smallest packed-volume mat without compromising comfort. To add warmth, we use Exkin® Platinum, a quiet non-woven fabric that reflects radiant heat loss back to the user and Thermolite® insulation to prevent convective heat loss between your body and the ground. All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.

  • Exkin Platinum® fabric and Thermolite® insulation are combined to prevent radiant and convective heat loss 
  • Multi-function valve for easy inflation, deflation and fine tuning of air pressure 
  • 40D rip-stop nylon face fabric offers the right balance between weight and durability 
  • Our TPU lamination process - one used in the medical and aeronautical industries but unique to the outdoor industry - is vastly superior to the roll-to-roll lamination process that is commonly used in outdoor products at present. The TPU bonds better and more consistently, virtually eliminating delamination issues.
