Work bag recommendations

[morechocolateneededtoday]

Looking for recommendations for a work bag that can comfortably accommodate a laptop, accessories and lunch. Depending on my client site, I use train or car to travel so I am thinking rucksack is going to be most practical but open to suggestions and something that does not look massive when on my back.

(My work clothes are casual - jeans with a jumper so I am not looking for anything formal)

Does not need to be branded but decent quality

Any recommendations please?

Knomo looks good.

I'd consider convertible backpacks - there seems to be more choice these days.

My Mia Tui rucksack looks smart and is holding up well. Knomo look lovely but were out of my budget.

Thank you both.
@TheFeistyFeminist which Mia Tui rucksack do you have? Does it fit a laptop in as the one I saw claims to fit iPad but no mention of laptop. Love the style though

I have a leather fossil backpack, it was called a men's weekender which annoyed me but perfect size, lasted 4 years so far and I love it. Used to have a satchel but it gave me back ache.
