Modular packing systems are becoming more popular because of increased airport security and generally more hectic travel. For example, individuals can pack dress shirts in a garment folder, shoes in a shoe bag, and undergarments in a mesh sack, then pack the modules in a suitcase. Put simply, every thing finally has its own bag, and each bag has its own place in the suitcase. This makes it (1) easier to find what you're looking for, (2) easier for security screeners to identify luggage contents, (3) easier to re-pack luggage and add/remove items without disrupting the other contents of the bag. Eagle Creek Pack-It products are the epitome of module packing: a large choice of bags, folders and cubes ranging from tiny to large and in many common colors.
