As mentioned above, excellent presentation. Only comments:
1. The knife and walking stick CANNOT be transported in the aircraft cabin. Either check the rucksack, or obtain a knife and walking sticks on arrival. I use a nylon laundry bag to check my rucksack, works well. The sack can then become my rucksack liner after arrival, to help keep the contents dry.
2. The diagram does not include the multiples of certain items needed. For example extra socks, underwear and t-shirts. These take up space / volume.
3. I concur with 1.5 liters of water, but recommend using multiple .5 liter, easily replaceable and very lightweight bottles. They can be distributed to different places to balance weight.
4. In addition to what is shown in the diagram, each person will have more toiletry and medical items as befits their individual circumstances. For example,m the diagram does not show a toothbrush and toothpaste. I have to carry nearly 1 kg per week of special nutritional items. Then, there are the multiple medicines that some people must take daily.
But as a simple starting place to visualize everything, this was excellent. Thank you.
