Fully equipped, very large mountain bike backpack for alpine cross or multi-day tours with excellently ventilated Aeroflex 3D back system. The shifting back length allows you to adjust the shoulder strap attachment to perfection. The spacious main compartment with hydration bladder holder can also be divided horizontally for clear organization. The spacious bottom compartment has space for a sleeping bag and a change of shoes for the evening. At the top front there is a valuables compartment with a mesh organizer. The large front compartment is divided into a tool compartment and behind it a document or map compartment. Large, elastic mesh outer pockets for protectors or drinking bottles are also on board. Even while riding, access to a cell phone pocket on the side and a small pocket on the right hip wing is always guaranteed. A helmet holder, reflective blinky holder and rain cover complete the lavish equipment. If necessary, the packing volume of the MTB backpack can be increased by 5 liters using a zipper, with the compression straps ensuring that the backpack contents are firmly secured.
