Strap fitting on the bottom now allow a tent or something to be attached there.
The top had two fittings, seen here; I added two so I can strap something to the top too.
I always like to keep my camera ready; I had in the past tied it to the chest strap, but then it falls off as soon as you undo that strap. One strategic karabiner solves that!
In case of room scarcity I often keep my mug and bowl dangling from the outside. I fixed a split ring to allow that, and I drilled holes into my cutlery, so that can dangle along! I have too many memories of hearing the call "dinner ready!" and then spending too much frustrating time looking for my spoon.
I'll bring big gloves; too big to reasonably fit inside my jacket pockets. So I attached a mesh stuff bag to the waist strap. I can put them in there if I don't need them!
