Whether it's riding across the alps or a multi-day tour on your mountain bike, the Bike Alpin W 24+4 is your ideal companion! The full-featured all-mountain backpack has plenty of character, both inside and out. Its excellently ventilated Aeroflex 3D suspension system will lighten your load on sweaty ascents. With a "shifting back length", the shoulder straps can be adjusted perfectly to any torso size. The generous main compartment with a hydration bladder garage can be divided horizontally for useful organization. The spacious bottom compartment can easily accommodate a sleeping bag or a change of shoes for the evening. At the top front, there's a valuables pocket with mesh organizer. The large front compartment divides into a well-designed tool compartment with a document or map pocket behind it. Large, stretch outer mesh pockets hold protectors or water bottles. A pocket for your phone at the side and a small pocket on the right hip wing provide 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 4 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.
