MOLLE, pronounced like Molly, the feminine name, is an acronym for MOdular Lightweight Load-carrying Equipment. It is used to define the current generation of load-bearing equipment and rucksacks utilized by the United States military. The system's modularity is derived from the use of PALS webbing, rows of heavy-duty nylon stitched onto the vest as to allow for attachment of various MOLLE-compatible pouches and accessories. This method of attachment has become somewhat of a standard for all quality modular military gear, replacing the click and stick system used in the earliest modular vest systems.
