Fontana II Backpack M can contain up to 11" slim laptop, a middle class DSLR camera with standard lens, an additional DSLR camera, two lenses and other extra accessories. Also, the inner mesh pocket is particularly convenient to store and carry small size accessories.
The zip on the left side of this backpack allows fast access to your camera with its lens on, without taking the backpack off. It is particularly convenient as it makes possible to have your camera at hand every time a good chance for shooting shows up. You can also have quick access to your other lens from the zip on the top.
The extractable anti-rain cover adds an extra plus of protection to your equipment during rainy days.
