I know some people who have forked out the money for really gucci medic bags, I've probably seen a half dozen different styles over the years, from stomps to the big PEP mountain rescue packs in OD and black.
I've tried several different commercial packs with different organizer systems, and I now carry a rebuilt CF jumpbag, fixed up by a mattech with an '82 pattern yolk and some internal modifications. I carry civi off the shelf organizer bags, one for a bvm, one for my suction, one for trauma, one for IV's and one for drugs. I've also got some nice civi stuff to put in it, too.
I bought some nice custom kits several years ago for my former unit, an all in one airway/trauma/drugs/oxygen pack, it was a heavy mother but it was basically everything in one bag, either on a shoulder strap or with two (poorly padded) backpack style straps.
I think we need to replace our issue jumpbag for mounted operations, and redesign a new bag to work with the body armour and tac vests and to support dismounted operations AND sustain the medic while packing his stores. With an increasing emphasis on light operations, we need to take advantage of emerging technologies, advanced and composite materials, for equipment. A BVM that takes up less space then a triangular bandage? They're out there. Traction splints you can fit in a pocket? Them too.
