So I am a paramedic for a private ambulance company where I am in a ambulance for several hours. My old 5.11 bag was starting to show it age and was bulky for the small area that is given. I decided to downsize and wanted to switch to a Oakley bag. I can fit a extra pair of boots, extra clothing, and just the truly essential items I need for a 12 shift. I am very happy with this bag and what it can hold.
