The Comfort Light sleeping mats feature hybrid layer Air Sprung Cell™ technology - a double layer of high resolution cells in the torso for maximum comfort and insulation, and a single layer of medium resolution cells in the head and legs for reduced weight. We use Exkin® Platinum, a quiet non-woven fabric, to reflect radiant heat loss back to the user and Thermolite® insulation to prevent convective heat loss between your body and the ground.


  • The Comfort Light Insulated Large is designed with 396 Air Sprung Cells. These revolutionary Air Sprung Cells™ are formed by a matrix of dot welds and function like individual coils in a pocket-sprung mattress for unrivalled support and comfort
  • The dot welds are offset to provide the highest resolution of Air Sprung Cells
  • Dual layer design ensures a level of built-in redundancy; if a puncture occurs in one layer of the mattress, the other layer remains fully functional
  • Because the two layers can be pressurized independently, the top layer can be fine-tuned to your personal comfort, while maintaining a high-pressure base layer for protection from rough or uneven terrain
  • Patent-pending multi-function valve for really fast and easy inflation, deflation and fine tuning of air pressure
  • The Exkin Platinum® non-woven layer is virtually silent and reflects back radiant heat to the sleeper
  • Thermolite® insulation prevents air circulation and heat loss due to convection
  • 40D rip-stop nylon face fabric offers the right balance between Weight: and durability
  • Unique aeronautical manufacturing technology: liquid-extruded TPU bonds permanently to the shell fabric, virtually eliminating delamination
  • An anti-microbial treatment is added to the TPU to prevent issues caused by warm, moist air trapped inside the mat
  • All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches and a spare silicone one-way valve insert
  • Inflation with one of Sea to Summit’s optional pumps (Jetstream or Airstream) takes only 30 to 60 seconds; mouth inflation incredibly requires only 8-12 full breaths. Deflation takes moments
