I have been traveling around the US and the world with this bag over the past year. I can say its a great investment. Currently, I am using it as my primary bag here in Afghanistan. I doubt that anyone will have this sort of issue but the straps are actually long enough to fit over Body Armor, which means it will definitely fit over any coat you can throw at it. My first trip over to Afghan, this bag was loaded with 48 POUNDS of gear and clothes and wasn't showing any signs of strain. While I have been here, I routinely carry between 30-38 pounds of clothes and gear and this bag takes it will ease. Great choice, great fit, and honestly, have not left home without it!
