Deuter Futura Vario 45+10 SL I used it a little for walks, but I haven't used it in the mountains, so there's almost no damage or dirt. It has two compartments and is easy to use, and its slim design is good for crossing paths on narrow mountain trails. The top lid goes up, so it can hold quite a lot. Also, the hip belt is strong, so it has excellent hold. Thank you for looking.
