As is more common these days, the suitcase unzips on the top instead of in the middle (also known as a clam-shell design). To me, this is the only way to go. It allows for you to pack deeper and utilize packing cubes better. It also makes it so much easier to open the suitcase as there’s nothing to fall out.
A unique feature about the Travelpro Versapack is a removable zip-in compartment/divider that attaches to the interior’s top section. The zip-in compartment that comes with the suitcase is a garment organizer, which could store some nicer items that you don’t want wrinkled. By having them zipped into the top, there shouldn’t be any weight sitting on them, pressing wrinkles into the fabric – smart.
You can purchase additional zip-in organizers to use with the suitcase. There are several to choose from. One is designed more for a suit, others for dirty or wet laundry, and yet another for smaller items.
