BrightLine Bags makes a modular Utility Bag system for Field Professionals called the FLEX System.
FLEX was created as an extension of the original BrightLine Bag in response to two years of accumulated feedback and requests from thousands of customers all over the globe.
And while FLEX was originally created for recreational and professional pilots, it was clear that lots of other field professionals (Law Enforcement, Emergency Medical, Military, Transportation, Marine, Service Technicians, Musicians, etc.) have the same need to be organized and be able to effectively make use of their gear.
The collection of interchangable modules and pockets allows these field professionals to configure different bags according to the gear-carrying needs of the different "missions" that they face from day to day.
