Built is a company that make lunch boxes, computer and camera cases, plus many other colorful and cheery stuff! They are Eco conscious (no need for those brown paper lunch bags any more!) and are made of durable neoprene. Neoprene is the fabric commonly used in scuba diver suits because it keeps things insulated and warm, but for lunches, cold!
I have this one!
