The Airzone Trek 45-55 trekking backpack from Lowe Alpine offers maximum comfort during 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 air to circulate pleasantly. 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 the backpack fits optimally to the body and distributes the load comfortably. The expandable lid adds 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 that securely hold a smartphone, camera, or some cash, keeping them easily accessible. Convenient for on-the-go access, the front zipper allows entry to the main compartment without having to reach from the top. The backpack is prepared for a hydration system that can be integrated as an accessory if needed. With the Airzone Trek 45-55 backpack, hut tours and long hikes become a true pleasure.
