Our Large Organizer pockets are big enough to fit bulky items like trauma dressings, but many responders use them for assessment tools etc. The pocket is 400d pack cloth on the bottom and sides, with a clear vinyl front, and opens with a large hook and loop top flap. It is sized to work with any of our modular equipment organizers and can fit anywhere the modulars can. The Large organizer is also designed to rip and stick into any of our MOS compatible kits. A great choice for hemorrhage control supplies. Medical supplies not included.
