This is a great bag. Only reason I didn't give 5 stars is for the few minor changes I would make. Overall the best feature is the removable interior trauma and airway bags. They swallow a HUGE amount of kit!!! I'm a tactical medic and have a lot of additional equipment that most EMS services would not carry and the bag easily stores it all.
The few changes I would make:
1. The outer pouch attached with cinch straps is useless. It adds a lot of bulk without much use. I cut it off.
2. The dividers inside the removable interior bags should be detachable. The interior of the removable bags should be Velcro giving the option to utilize different interior securing variations.
All in all, great bag. Especially for the price.
