DELSEY PARIS Rempart collection is the cross-section of function and fashion, with a sleek design and modular stacking capabilities. No matter their size, each suitcase can be stacked and secured on top of each other, thanks to the interlocking grooves of the luggage shells. The outer shell is made of an ultra-shock-resistant polycarbonate. Each piece is equipped with DELSEY patented SECURITECH® Zip that is 3 times more resistant than a standard zipper. An integrated TSA-accepted combination lock enables you to secure your luggage using your own 3-digit code and allows the Transport Safety Authority (TSA) to open your luggage using a special key, without damaging it. The interior is expandable for maximum flexibility and features two full packing compartments with webbing straps and a zipped pocket on one side, as well as a lined divider with two mesh pockets on the other side. Thanks to the removable and washable lining, you no longer need to worry about spills or dirt inside your suitcase: unzip the lining and wash it on a delicate cycle so the inside of your bag is perfectly clean for your next getaway! This carry-on features durable and quiet wheels for superior mobility, and three carry handles - on the top, on the side, and at the bottom - providing maximum convenience when lifting a fully packed case. It has been designed to fit in the overhead compartment of most domestic airlines. The size and weight restrictions for carry-on luggage vary by airline, please see our Airline Carry-On Guide or contact your airline for more information.
