I did not expect to see a grocery store for at least a week and a half when I took the photo, and at that point had not seen one for six days, so this segment of this trip might be the heaviest I ever packed:
Frontloaders, 25 liters.
Backloaders, 40 liters.
Rack Pack, 31 liters.
Handlebar bag, roughly 8 to 10, I will call it 9 as a guess.
Drybag between Rack Pack and seatpost, probably about 8 liters at the time of photo.
Raingear strapped on top of front rollers, probably about 3 liters (great spot for that, available at a moments notice without even openning a pannier).
Small triangular bag on top of top tube and strapped to seatpost with two tubes and patch kit, less than a half so rounding off to nearest whole number at zero liters.
Nobody else appears to be including water in volume, so I won't, but that is three bottles, one liter each.
That adds up to 116 liters excluding water. I do not want to know what it weighed. But about 40 liters of that was food, so volume got smaller over time.
No backpack.
