It all started with a mom, her three kids, some mushy blueberries and one genius idea… soon after Packit was born! Packit is the first foldable, freezable bag to keep food and drinks cool for hours—no ice packs needed. PackIt bags have a patented technology that chills items just like a fridge all day. The secret is a freezable gel built into the walls of the bag. Simply collapse and store the entire bag in the freezer overnight. By morning, the walls of the bag will be completely frozen and will generate waves of cold air that chill your food and drinks from all sides.
