This is a nice little bag that I like to take when I go hiking. Since the bag is small, it makes the trip less strenuous.
I am able to fit either my 6D/24-105 or 6D/150-600 along with filters and cables. This pack fits just enough to allow packing light. It also has a small compartment on the side to fit a 1L camelpack water pouch. It also has a rain proof coat that folds out from the bottom of the pack. I used this not too long ago when it was pouring down rain. When I got back to the car, the backpack was completely dry and none of my equipment took water from soaking through. Great little pack!
