The Fritzi52 is a large backpack in courier style with a beautiful, matt material look. If necessary, the generous storage space can be expanded upwards using the folding function. A snap button under the flap at the front ensures a secure feeling when worn. Inside the bag, a large zipped compartment and slots create good organization. Another small, hidden zippered pocket on the back between the straps provides additional secured storage. The shoulder straps are continuously and individually adjustable to the desired length.
