Roncato Uno SL is the backbone of all Roncato products. This innovative concept was entirely designed and created in Italy. The pieces combine light and elastic Polycarbonate with secure Polypropylene locks. Roncato Uno SL is the first suitcase in Polycarbonate that has a closing system with a TSA combination lock which is required for travelling to the US. It is equipped with three service handles, four swivel wheels for easy movement and a retractable towing system with push button.
