The Airzone Trek 45-55 trekking backpack from Lowe Alpine offers maximum comfort on trekking and hut tours. The seamless FormKnit back panel ensures excellent ventilation, preventing body heat from accumulating on the back. The shoulder straps and hip belt are also made from breathable, finely knitted material, allowing for pleasant air circulation. The outer material of the backpack is water-repellent and particularly abrasion-resistant. In heavy rain, a rain cover can be found in the lower compartment, which can be quickly pulled over the backpack. The carrying system can be adjusted in back length between 48 and 53 cm, ensuring an optimal fit and comfortable weight distribution. The expandable lid provides an additional 10 liters of volume. Numerous attachment loops, compression straps, and pockets ensure that trekking poles, an ice axe, keys, a rain jacket, and much more can be compactly stored directly on the backpack. The hip belt features two zippered pockets for securely storing a smartphone, camera, or some cash, keeping them easily accessible. Convenient for on-the-go access, the front zipper allows access to the contents without having to reach through the top. The backpack is also prepared for a hydration system, which can be integrated as an accessory if needed. With the Airzone Trek 45-55 backpack, hut tours and long hikes become a true pleasure.
