Thule Alltrail X 35L

"The Alltrail X 35L from Thule is the perfect companion for longer trekking tours and versatile outdooradventures. Made from 50% recycled waxed polyestercanvas, this backpack impresses with its exceptional robustness and water repellency, which is far superior to traditional waxed cotton canvas. With a 10 cm adjustable back length, the backpack guarantees an optimal fit that can be individually adjusted."
"Particularly practical is the versatile hydration bladder compartment made from Air-mesh, which not only provides hydration but can also be used as a laptop compartment for a MacBooku00u00ae up to 15 inches. The clever u201eShove-itu201c pocket on the front allows quick access to frequently used equipment, while two hip belt pockets are ideal for cell phones or snacks."
"A breathable back panel ensures that there is no heat build-up, even during intensive activities. Additional zippered pockets on the front and on the lid offer space for smaller items. With side compression straps and attachment points, additional equipment can be attached to the outside of the backpack. Hiking poles or ice axes can be easily attached to the fastening loops. The detachable, color-contrasting rain cover keeps your luggage dry even in stormy weather and ensures that you are prepared for any weather conditions"
