Munchkin Baby-on-the-Go Bag is travel bag that's expandable and holds a ton of baby stuff. The bag's insulation makes it ideal for carrying food since it preserves the temperature of the contents for hours. The bag zips around and thus fits easily inside a diaper bag. The special mesh pocket of the bag holds the cold or warm packs. The stroller attachment loop and shoulder strap keep the bag handy enough to move around easily. The fabric is long lasting and easy to clean.
