This is the perfect lunch bag. It holds a lot more than it looks like. Here is what I generally put in it every day:
Breakfast- coconut water, cereal, and some fruit (usually grapes).
Lunch- Lean cuisine (in the box), Just for One veggie package, bottle of Powerade Zero, and a desert bar.
The shell is soft and flexible, so it kind of molds to fit everything you need. It is also well insulated, which is good because the refrigerator where I work is disgusting, so I keep my lunch bag in my locker, and everything still stays nice and cold. When it gets dirty, you can just throw it in the washer and wash it. I have the white bag with the polka dots and although its pretty, I wish I would have bought a darker one. The white shows dirt to easily. Thank goodness it's machine washable.
