I've been looking for one of these AnyBags. But none is so great, flexible and practical as this one. I put it into my Deuter Trans Alpine backpack where he fits in. Before that, I've also taken the backpack and taken lenses like cameras in wraps, used quiver made of neoprene or other. Downside is when everything is unpacked and a lens change is to be made has not pursue the time the lenses back in cloth. At the end shambles is in the backpack, the lenses are at risk of damaging each other. A camera bag I have also considered buying, but again a bag or backpack more? No place, no desire. This bag has no prescribed format by the flexible outer wall and feels in oval, rectangular as well environment. The separator can be adjusted to the required equipment. The bag can be closed up around with draw cords. The outer fabric forms a hood and protects when one carries more items in the backpack. Although I've accrued in the Transalpine detachable wet clothing as camera bag with the rest of the main compartment. One can this camera bag also PrimaSolo carry around to the draw cords. Not for long, but when the backpack does not need to be dragged through the whole set, which is quite convenient.
Anyway, I can carry lenses with lids removed already at hand, they are well padded, and everything is really easily in a pocket, adapts to all types of pockets and also solo is very convenient.
