Mountain Runner 20 is a backpack designed for trail running, in elastic fabric, with a large capacity to face even long-lasting races. Ideal and comfortable solution for storing what you need while running. Belt and shoulder straps are adjustable in order to adapt to the body in an optimal way and minimize oscillations. The volume (both on the back and on the shoulder straps) is organized in several independent pockets, to better manage the load. The lateral elastic bands allow to compact the load. The back and shoulder straps are breathable and soft.
