This luggage set arrived earlier than estimated. I travel extensively and have come to view luggage as disposable items unfortunately. Most simply are not built for continuous use. With that said, this set was an absolute surprise straight out of the box. I am impressed with the dual wheel per caster design, the very sturdy trolly handle and most especially the lock design. The inner compartment of the suitcase is segregated to allow for clean and dirty clothes separation via a zipper section and a compression strap on the other side. The backpack has excellent storage and sorting compartments and capabilities; an area for your laptop and or electronics away and protected from the rest of your pack. Front and side storage as well as padded shoulder straps and a trolley strap to allow for easy transportation. The small bag is designed to be water resistant inside for worry free storage of wet items such as shampoo, nail polish or the likes. All has very good stitching and quality construction. For the price and quality, this is an absolute no brainer. I'm about to order another set.
