While the rear window MOLLE looks rad, you may want to reconsider what you have mounted to it. Regardless of how securely you may have them mounted, the fire ext & hatchet can easily come lose & kill you or other occupants in the event of a crash. Can’t see exactly how you have the extinguisher mounted, but those flimsy Quick Fists holding the hatchet will immediately fail when force is exerted. Beware.
