Top-quality hiking backpack with a volume of 50 liters in back size S/M (torso length 43-52 cm). The unique back system forms one compact unit that allows unrestricted movement with the backpack. The ventilation mesh with large meshes is stretched on the perimeter frame not only at the back, but is also extended to the shoulders and waist belt. It has a stretch construction, with a predefined shape and length-adjustable flaps. Thanks to this, the backpack offers maximum ventilation in all directions, stability and comfort when carrying heavy loads. We recommend it for demanding outdoor activities (expeditions, trekking, alpine tourism).
