Ultralight and compact, this exceptionally comfortable mat is ideal when light and fast is your aim and getting a great night's sleep is essential for the next day's adventure.

Sea to Summit says:

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.

The air sprung cells are the core technology of this mat, allowing you to have a comfortable nights sleep. Instead of the typical baffled construction, these sleeping mats are constructed using a matrix of air cells that move independently to conform to your body’s shape without affecting adjacent cells. Translated to backpacker-speak, that means you don’t flatten out spots under, say, your hipbones or shoulders.

The Exkin Platinum thermal technology reflects radiant heat loss back to you, while the Thermolite insulation lofts up inside the Air Sprung Cells to prevent convective heat loss from your warm body to the cold ground. The Exkin Platinum and Thermolite technologies are combined in this mat to ensure you stay as warm as possible while carrying the lightest weight.

The Ultralight range is not as warm as the comfort Light ranger however it is lighter and has a much smaller pack size.

  • 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.
