In over 41 years in EMS, I have used jump kits from many manf. like Plano, Bashaw, Reeves, EMP, Ferno, Thomas, Iron Duck, Pacific Packs, and just purchased an LA gear backpack as a "Bug Out" bag.
Iron Duck has a good basic jump kit and was very durable. Blackhawk has a nice tactical medic bag and accessories. I am not familiar with the Statgear. But Pacific Packs and LA Gear seem to have bags that lend themselves to better interior ALS organization, and bigger teeth on the pack zippers are nicely constructed. (IMHO the finer the zipper, the more likely it is to mess up.)
Many services also have a Medical emergency kit, a Trauma Kit and a separate Pediatric jump bag. The Ferno I have is really "big", set up for medical situations. Then I have a Conterra O2 pack, and Pacific Pack for Trauma.
So, you may find you need different interior layouts and that one manufacturer doesn't supply bags for all your needs. Some kits for pediatric patients may require smaller color-coded bags - are those available?
Some vendors will ship you bags for consideration, and you might see if you can get something you like shipped for crews to do a group evaluation. Until you try and put items into the pack, you cannot properly check it out.
Other considerations:
Are jump kits personally organized by each crew, or is there a standard assembly used by the service? Are additional dividers or pads available? Do you prefer a different color bag for a specific use? Where will you store and secure the bag? Will it fit within the space in the response vehicle or ambulance?
Good luck, and let us know what works for you!
