The new Salewa Airstream+ support system offers maximum ventilation and at the same time a high level of comfort when carrying loads. Although the rucksack sits close to the back – this allows the wearer to control the load well, especially when carrying heavy baggage – numerous air vents ensure unhindered circulation of air. The back is noticeably better ventilated and remains drier. The Altitude is designed for optimal freedom of movement. The rucksack sits comfortably and jolt-free on the back especially on demanding trails or on easy high-altitude and climbing trips. This is an invaluable advantage.
