Full-featured, very large mountain bike backpack for trans-alp or multi-day tours with the Aeroflex 3D suspension system for excellent ventilation. The "shifting back length" allows you to perfectly adjust the shoulder straps. The generous main compartment with a hydration bladder garage can be divided horizontally for clear organization. The spacious bottom compartment has space for your sleeping bag and a change of shoes for the evening. At the top front, there's a valuables pocket with mesh organizer. The large front compartment is divided into a tool compartment with a document or map pocket behind it. Large, stretch outer mesh pockets offer space for protectors or water bottles. A pocket at the side for your phone and a small pocket on the right hip wing provide easy-access, even while riding. A helmet holder, reflective safety light attachment and rain cover round out its many features. If necessary, the pack volume can be unzipped and expanded by 5 liters, while the compression straps ensure your gear doesn't jostle around. The VAUDE Green Shape label stands for environmentally-friendly, functional products made from sustainable and bluesign certified materials.
