With the carry-on sizes, you can add your own power pack to the charging point near the TSA lock. Each size has an expandable feature for extra packing space. 8 multidirectional wheels promise a smooth journey from home to your destination, and Securi tech double zippers (3x stronger than regular ones) keep your belongings safe. The interior is thoughtfully lined with a fully zippable side and compression straps on the other. Delsey's new range is a great choice for your next journey! This Delsey range features a clever top opening feature meaning the opening to the suitcase is like a softsided case, not the stadard middle opening that is standard on a hardsided case. Great for space saving while packing/Unpacking.
