A soft sided insulated cooler bag has a base and side panels. The base includes a rigid or semi-rigid reinforcement or batten that serve to provide a relatively hard or stiff edge about which the bag can be panel folded over on itself. The upper edge of the bag has a length that is as great as half the periphery of the bottom panel. The bag can be collapsed to a flat position and then panel folded to a storage position. Retainers are provided to keep the bag in the storage position.
