The Rupal 45+ backpack by Vaude is a versatile mountaineer backpack for all seasons. A pair of skis can be attached to it just as easily as a pick or rope. There are also compartments for a hydration system and safety equipment in the winter. Its volume of 45 liters is sufficient even for more demanding hut tours in winter. If extra gear is required than the main compartment can handle, the lid is adjustable in height and allows a volume expansion. The Rupal 45+ backpack is engineered and manufactured to GreenShape's strict criteria for a lower environmental footprint. It combines great technical knowledge with a clear conscience.
