The casino I work for recently bought 3 of these med packs about 3 months ago. We kept everything in them and added a BP cuff, Pulse Ox, Blood Glucose kit, and a little clipboard with a patient refusal attached. All of that fit into the pack as well. Some of the EMT's do put their stethoscope in the pack also. All of our EMT's carry them while on shift so that our patient contact time is shorter. Then the next incoming EMT will grab the larger bags. So far they have been a great success and have held up wonderfully. The only thing I would improve is adding an extender belt to the kit if you want to where it like a back pack. All in all, A great buy for the price.
