Help me find a bag, please

[Silverbook]

Hi,
I've got 2 days and a night in London. Flying in then lots of walking and a theatre visit. Looking for a bag that can
a) be my carry on/under the seat bag
b) a toiletry bag, trainers and spare clothes
c) not be bulky as I'l have it with me through the day.
Desirable criteria- a zipped/separate pocket for easy access to phone, bank cards etc

Not fussy about anything else. Would love your ideas! Thank you

Look at Mia TUI bags.

I’ll go for Kipling bag for this - the space is organized, lots of separate pockets, nice colour choice and light .
