The revival of a classic. It was even present when Deuter revolutionized the backpack market in 1984 by introducing the first fully ventilated back for hiking backpacks - featuring the widely imitated Aircomfort system. Its classic look harks back to the good old days while offering modern features. Maximum ventilation is our guiding principle when it comes to backpacks with small to medium volume for use in lighter terrain. The robust core of the Aircomfort systems is the permanently elastic spring steel frame. This ensures that the special airy mesh remains taut and stable even under heavy loads, creating a ventilation space between the backpack and the back, allowing moisture-laden air to evaporate freely.
