Mobility by bicycle has become a part of modern urban lifestyle. The bag combines elegant appearance with sophisticated functionality and a design that is based on flexible use in the office, family and everyday life. The robust nylon material with a textile look and texture ensures long life and high functionality. The bag attaches to all standard bicycle racks and converts using integrated straps to a practical backpack. The comfortable handle and padded notebook compartment provide variable application possibilities. The Rucksak Bag bridges the gap between chic lifestyle and environmentally conscious urban mobility.
