A lightweight, portable bag is provided with one primary compartment and at least one secondary compartment. An internal liner material is provided in each of the primary and secondary compartments. Each of the internal liner materials is flexible and collapsible. Therefore, when an item such as a breast pump is inserted into one of the secondary compartments, the secondary compartment would extend into the primary compartment, thereby reducing the volume of the primary compartment and simultaneously increasing the volume of the secondary compartment. |
