Sorry Tia, I was on vacation.
Jon is correct, only the bottom has Nylon, the sides are canvas. You could machine wash it. If it fits it would be a tight fit. On the F-2 Backpack we made it so that the flap between the camera section and the storage area could open to accomodate bigger cameras. We didn't add this feature to the F-3 Backpack.
Also, we are working now on interior shots loaded with equipment.
