The opinion of Aventure Nordique

Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground.

Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with our Air Sprung Cell™ dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall.


  • Includes an Airstream Pump that is integrated into the stuff sack for quick and easy inflation

  • Extra thick (XT) loop baffle Air Sprung Cells

  • Lightweight, quiet and grippy 30/40D Nylon fabric, field repairable with included self-adhesive patches

  • Ultra-Fresh anti-microbial treatment is added to the TPU formula to prevent internal mould growth

  • Air Sprung Cells for a more comfortable sleep

  • Multi-functional, high flow-rate valve

  • PillowLock attaches your Aeros pillow to your mat, holding it in place for a slip-free sleep
