TRUCO is designed to work like a regular CarryOn, that based on the overhead space scenario encountered during boarding, can be separated into smaller piece to remedy the situation and provide peace of mind. Main Piece, designed as a small size CarryOn, it can be use as such for small trips. When used as the main piece of TRUCO is recommended to pack all belongings that are less valuable and not needed during the flight in this piece. This way if you do not have space on the overhead compartment in your area, you can store it somewhere else or check it in if necessary. Front Piece, designed as a briefcase, it clicks to the front of the Main Piece to extend the size of the CarryOn serving as perfect space for your laptop or for additional garments. As part of the TRUCO concept, it can be detached from the Main Piece to be stored away under the seat, or in your overhead compartment separate from the Main Piece if there is not enough room for both to fit in the storage area. Top Piece, designed as a Valuable Tote, it clicks on the top of the Main Piece and Front piece to complete the full size Travel Utility CarryOn, providing the traveler a perfect bag to keep all the electronics, documents and valuable items that it will use and need throughout the flight. This piece can be separated from the other pieces and be stored under the seat for easy access, while the rest of the CarryOn goes on the overhead space or anywhere were space is available.
