Don't say it's over - UPCYCLING BAGS According to this motto, we build unique bags from old tractor, motorbike, bicycle and fire hoses, sails, truck tarpaulins and air mattresses. Leonca bags are mainly made from materials that would otherwise have been thrown away. All of our products are therefore truly unique pieces with a story all of their own. This kind of sustainable consumption sends a visible signal against the throwaway society.
