Nice, thank you. NCD though? Non cummunicable disease? Non convergent discourse?

No idea what this is supposed to be but lol, good work

Couldn’t find a specific model/brand other than this relatively expensive german brand, but the concept is easy and cheap so i guess you could find better.

I generally recommend this type of backpack since its 100% waterproof, basically dirtproof, has no zippers or any other parts that can brake. More ore less wear and tear proof. They contain huge volumes, but have little organization features.I got one thats in use for over 20years.

Tldr: max. Funktionality but you also look functional (german tourist syndrome)
