I agree 100%. Proper clothing is your number 1 essential. All else is a matter of how comfy you want to be IMO.
The list is a good one. I would expand it to 12-15 essentials to include tarp, water purification method and cordage but as a start it's a good one.
well said, I will just add good foot wear/boots aswell, when your hiking or tramping etc looking after your feet and body is number 1 priority. If you cant walk and your not warm yous stuffed
