Mammut Lithium 15

"The Lithium 15 from Mammut is the ideal companion for anyone who values lightness and compactness when hiking and fitnesstraining. This backpack, the smallest in the renowned Lithium series, is made from over 89% recycled materials and impresses with its PFC-free, permanently water-repellent finish. The particularly lightweight and highly breathable EVAshoulder padding ensures a high level of comfort, while the 3D EVA-foam-ribbed padding with air channels ensures optimum ventilation."
"Practical features make the Lithium 15 an indispensable accessory: An integrated, detachable rain cover provides reliable protection from unexpected showers. The padded harness, which is also detachable, has a fold-out pocket for your cell phone so that you always have it to hand. The backpack is also compatible with a hydration system, which makes it particularly attractive for longer tours"
"The well thought-out features of the Lithium 15 include a large front pocket with zipper, a zippered pocket with key holder and two mesh side pockets that are easily accessible while walking. The trekking pole holder and the forward-pull-hu00fcft strap adjustment round off the functional design and offer additional comfort on your adventures."
