The bag is fully washable and has two insulated drink holders, perfect for a cup or a bottle. In the main compartment, items like shoes, a sun hat, or your favorite snack can be stored. The small pouch in the front can hold valuables like keys, money, and a phone. When you move away from the stroller, you can detach the small pouch with a zipper and take it with you. The foldable design does not interfere with folding the stroller.
