The opinion of Aventure Nordique

Lightweight all-season comfort and performance. Thicker, lighter self inflating mattress with Delta Cores. Delta Core Technology: maximise the comfort and thickness of the mattress while minimising weight and bulk.


  • Large horizontal triangular cores reduce the weight and bulk without sacrifing support and comfort.

  • PU foam is ticker on top of each Delta Core for better insulation directly under you. Continuous foam layer on top and bottom of Delta Cores ensuring consistent warmth along entire lenght of the mat, and better bonding with shell fabrics.

  • Diagonal supporting foam walls help inflate the mattress and creates a more compact rolled mat.

  • Anti-slip print on base of mat, helps hold your mat in place when camping on sloping ground is unavoidable.

  • Multi-fonctional, high flow-rate valve. Allows easy inflation, one-way deflation (prevents unwanted reinflation while rolling up mat) and fine tuning for comfort.
