Timbuk2 San Francisco: Timbuk2's Delores Chiller filled a void in my life. It's neither too large nor too small, and it fits inside a Timbuk2 classic-size messenger bag. I carry my lunch in it to work. When I go to the river or the park, I pack it full of beer. When I take a car trip with my family, it carries our snacks, sandwiches, and beverages. It's not too heavy. It's not too bulky. It easily and comfortably carries everything I need.
