EDC backpack from a company that makes backpacks for nomads (NOMATIC (US)/ GOMATIC(EU)). If you are not familiar with the brand, I recommend starting with video reviews. In the same line of nomad brands there are Aer, Peak Design and etc. Over the last 3–4 years I have traveled around Russia, Georgia and Turkey with it. There have been 10–15 day trips only with this backpack.

Condition: good; there are signs of use and minor scuffs, but no holes, tears, or any functional issues.

Protective laptop compartment for up to 16"
Compartment for packing cubes / travel items
Top pocket for glasses
Organizer for gadgets, documents and RFID pocket for passport/wallet
Side pockets for bottle or umbrella
Rigid back and very sturdy construction — keeps its shape and protects the contents

Price: $200

PM me. If $200 for Nomatic seems expensive, I recommend looking at mass-market options — the selection is noticeably closer to your price expectations, which you can definitely manage.
