What is PALS/MOLLE?
MOLLE (pronounced /ˈmɒl.liː/, similar in pronunciation to the name Molly) is an acronym for Modular Lightweight Load-carrying Equipment. It is used to define the current generation of load-bearing equipment and backpacks used by a number of NATO armed forces, especially the British Army and the United States Army.
The system’s modularity is derived from the use of Pouch Attachment Ladder System (PALS) webbing equipment as rows of heavy-duty nylon stitched onto the vest to allow for the attachment of various compatible pouches and accessories. This method of attachment has become a de facto standard for modular tactical gear, replacing the All-purpose Lightweight Individual Carrying Equipment (ALICE) system used in the earliest modular vest systems (which is still in use with many police forces).
What kind of stuff can I mount?
Almost anything, if you are a hunter you can strap magazines or ammunition pouches to it, if you think you may need a first aid kit in a hurry, then you can get velcro backed pads that attach a first aid kit, you can stick water bottles with drinking straws, map pouches, equipment pouches, damn near anything can be mounted to the back of a PALS compatible system.
