Katie, I use a Lowepro backpack bag for my Bronica gear, 4 lenses, filters and assorted 'stuff', not sure which model it is but all up weighs 7.5 kg. The bag is very rugged,
padded with moveable velcro strips to suit any given set-up..the thing is, its really well designed with adjustable straps and belts so when this very small female is trudging along for miles in the middle of nowhere, the weight is so well distributed that I hardly notice how heavy it is.....as for looking chic and stylish...there's usually nobody around to impress anyway.
