...and I'll be the coolest guy in the office.

I've seen it online many times but I have yet to find it in a store so I can see the size. I take a lot of food with me to work and I worry that may not be able to fit my substantial caloric haul.

I picked it up today. It's a fairly good size. It could fit a thermos no problem. It looks like it should fit my lunch as long as I stop brining loaves of bread to work to make multiple sandwiches.
