Self Inflating, Compact, and Super Lightweight.

The SIM UL is the ultra light version of Exped's SIM mats. Lighter in weight and smaller in packed size. An all-round self-inflating mat. Warm, compact, super lightweight and affordable. A fantastic first sleeping mat for anyone. It will be years before you yearn for more out of your mat. 

Key Features Include:

  • Safe: Foam-core mats still provide comfort and insulation even if the mat is punctured.
  • Excellent next-to-skin-comfort and an effective honeycomb slip-resistant pattern embossed onto the face fabric.
  • Separate flat valves for inflation and deflation simplify handling. These are also more durable and protected from damage as they are flat in design and non protruding.
  • Zoning of mat for maximal weight reduction: torso area is lightened with horizontal channels where head and leg areas are additionally vertically hollowed.
  • Warranty of 5 years on materials and workmanship.
