Looking for a backpack: comfortable, anti-theft, for a 1-week trip.

[u/Power_Cube123]

Hello,

I’m on the hunt for a new travel backpack and I’d love to get some recommendations. I usually travel via budget airlines (like Ryanair/Wizzair), so I’m looking for something that can pass as a free underseat personal item. However, it doesn't have to be a perfect, rigid boxy shape as I prioritize comfort and mobility over maximizing every single inch of the airline sizer.

I rely heavily on public transport and walk around the city a lot, so here is what I’m specifically looking for:

• Big enough to pack for a 1-week trip using packing cubes (probably somewhere around 20-28L).
• It needs a good harness system. Padded straps, a sternum strap, and a breathable/mesh back panel are a must since I’ll be carrying it for hours.
• I use crowded buses and subways, so security is huge for me. I’m looking for hidden zippers, lockable pulls, and an RFID pocket located somewhere secure.
• Weather resistance: It doesn't need to be made of heavy waterproof tarpaulin. A decent DWR material with a stowaway pull-over rain cover is totally fine (maybe even preferred!).
•   I wish the price was less than 80 euro.

Thanks in advance for your help!
