A handy and convenient improvement on the insulated lunch bag

PackIt is a freezable, foldable lunch bag that the manufacturer says will keep food fresh for up to 10 hours. The personal cooler bag gets the job done without resorting to melting ice or bulky, toxic ice packs. PackIts come in a variety of styles and sizes — for mini, individual and social lunches; accommodating single and double bottles; for bringing frozen and refrigerated food home from market — priced between $15 and $27. Store it folded in the freezer until you’re ready to pack it. Available online and many retailers.
