Deuter FUTURA 23 has been developed for athletic hikers looking for a comfortable daypack with maximum ventilation. The backpack provides increased performance thanks to the Deuter innovative Aircomfort carry system. At the heart of the Aircomfort system is its flexible spring steel frame. It is extremely durable, provides stable tension for the airy back mesh and creates the ventilation space between pack and the wearer´s back for the moist, warm air to dissipate - thus, providing maximum ventilation. In addition, the Aircomfort system provides pivoting shoulder straps, ergonomic hip fins, stabiliser straps, and chest straps to increase its comfort and to secure the fit. In order to comply with the highest technical requirements, Futura 23 features front stash pocket, two stretch side pockets, front pocket with organiser section, special compartment in the inside of the backpack to keep valuables safe and elasticated inner compartment for storing wet/sweaty clothing etc. What´s more, there is detachable rain cover, trekking pole attachment and loops for helmet holder. It is compatible with 3.0 litre drinking system.
