The Compact is a bike backpack for mountain bikers that sits comfortably and tight on the back. It impresses above all with its perfect features: It has an extra compartment for the drinking bottle, a separate compartment for the smartphone, a well-organized tool pocket, two zipper pockets on the hip fins and two elastic side pockets. There is also the possibility to expand the volume of the backpack. The half-shell helmet can easily be hung in the front in the fastening clips, while the side compression straps are suitable for fixing the full-face helmet
