Abstract: The invention relates to a rucksack (1) with a horizontally and vertically rear-ventilated air conditioning zone (6). It is composed of a shoulder strap carrying system (2), a rear wall (3) with a stiffening frame (4), and a mesh (5) stretched across the rear wall and/or across the stiffening frame for creating the rear-ventilated air conditioning zone (6) between the rear wall (3) and the back of a rucksack wearer. By virtue of the stretched mesh (5), the rear wall (3) is kept away from the back of the wearer both in the hip region and in the shoulder region and allows both a horizontal and a vertical exchange of air. In a variable embodiment of the rucksack (1), the rucksack (1) can optionally be adapted to the body of the wearer by attaching the shoulder straps (2) in the shoulder-side region in a horizontally and vertically adjustable manner to a baseplate (15) attached to the mesh (5).
