Diaper bags are an indispensable method of transporting everything needed to take a baby or infant anywhere, whether it is a short trip to the store or an extended vacation. The most important feature is functionality. Multiple interior and exterior compartments are necessary to hold essentials like diapers, powder, baby wipes, bottles, formula, pacifiers and toys. Many totes have valuable features including insulated bottle holders, protective feet on the base, adjustable shoulder straps, hand grips and stroller straps. Some bags even open flat to reveal a removable changing mat. Diaper bags equipped with matching zippered pouches come in handy to temporarily store dirty diapers and used toiletries until they can be disposed of properly. Durable fabrics like leather, nylon, canvas and polyester stand up to heavy abuse, while fashionable colors and prints keep users in style. Popular shapes are the messenger, hobo, tote, purse and backpack. Smaller bags are ideal for daily use, while overnight excursions mandate a larger bag.
