I work Private Security and I am always looking for a bigger better bag. I don't use my medic bag for medical I use it to transport my duty belt and all accessories. This bag is huge. A fully loaded duty belt and holster along with a small pelican case in the main compartment with enough room to hold a change of street clothes and toiletry bag in the upper compartment. This bag has pockets galore to stow small gear. I have the organizers but haven't found much use for them yet. very sturdy and comfortable to wear with oversized straps and thick padding.
