The two-chamber blue hiking backpack 45 liters is made of mechanically resistant ripstop recycled material. It has an upper and lower entrance to the main chamber. The sliding Vario back system with a dry zip can be adjusted to the length of the back, as well as the adjustable padded shoulder straps and a waist belt with a pocket. The back system and shoulder straps are also made of breathable and quick-drying durable mesh. At the top of the shoulders, the backpack can be tightened or loosened with a strap, thus regulating the load on the back according to the needs in the field. On the chest strap, which ensures the stability of the shoulder straps, you will find an emergency whistle. The lid has an inner and outer pocket for better division of small items on the road. There are also holders for an ice axe or trekking poles or other necessary material. Two spacious side pockets and a front mesh pocket can be used for quick storage of clothing or small items. The backpack can be easily tightened with side compression straps to a smaller volume. There is an integrated rain cover with reflective elements and a pocket for a water reservoir with an outlet. The backpack is made of recycled polyester (21 PET bottles with a volume of 0.5l were recycled for the production of one piece). The production of this product has therefore resulted in significant energy savings and a reduction in carbon footprint. sliding back system - Vario system upper and lower entrance to the main compartment reinforced back; padded shoulder straps Shaped waist belt with two pockets chest strap with whistle lid with inner and outer pockets side compression straps two ice axe or trekking pole holders blinker mount  two spacious side pockets front mesh pocket pocket with outlet for a water bag integrated rain cover with reflective elements
