It was much bigger than I expected so isn't really suitable as a work lunch bag. However would be perfect for a stylish picnic cooler or shopping cooler bag. Doesn't really work as a handbag as when it's full of other stuff, your food isn't really kept cool.
Some separate pockets or sections with zips would be great so stuff isn't lost in the large bag and you could put your lunch in a separate section with an ice brick.
Took it gocery shopping and it fit my entire cold foods in it. Meat, dairy and frozen. Pretty impressed. Plus it looked great.
