☺ Please check the profile ☺ I purchased this about 4 years ago and used it for a 10-day trek in Nepal. I washed it once with Emal at that time to remove dirt. Overall, it's clean, but there are some faint stains that I couldn't completely remove. Please be aware of this. The main features of this alpine pack are: Salewa's unique comfortable "Split Shoulder Straps" construction. 3D back panel construction that allows for airflow. This construction might be a concern for snow accumulation and clogging in winter, but there are drains at the bottom and sides to address this. The rope holder is a very quick one-action system. It supports double ice axes and hydration. A helmet can also fit in the front pocket. Capacity: 32L Weight: 950g (minimum 680g)
