The outside of the Pro Light Air-55 is made of highly durable, water-repellent rip-stop nylon fabric, which is additionally reinforced at the corners and the bottom. A protective rain cover is also included for protection against extreme weather conditions. The trolley gets its stable structure from an internal EVA moulded shell. Inside, customizable dividers, padded with Manfrotto's Camera Protection System, protect the equipment from shocks while effectively reducing vibrations. In addition, the trolley is equipped with high-quality, robust and smooth-running zippers that allow quick access to the contents of the case. Two smooth-running and durable wheels in combination with two stable floor feet, reinforced corners and special protective strips ensure safe transport.
