MOLLE vests are what the military uses to carry around their gear. You start with a vest of your choice. Each has a different layout of MOLLE connections. Then you can add MOLLE components to your vest until it's full. This gives you a completely customizable vest. Need more room for paint? Then get pod holders. Need a map holder for a big scenario game? You can do it. Because MOLLE connections are standardized, you can also use different brands of MOLLE components on any MOLLE vest.
