Ladies, need help for a durable everyday backpack

I'm looking for a backpack to free my hands whenever I'm out and about (often with child). I'd love to find something not too bulky, versatile style wise, and durable ofc.

I'm open to all materials, colors and prints; I just need something that is ok for the city and that wouldn't clash with outfits that are more put together.

Any brand you feel like recommending? Or general suggestion?

Save a girl from buying yet another faux leather backpack that will disintegrate in a couple years at best...

Thank you <3
