There is room for a few changes of clothes, toiletries and make up, plus a compartment for your iPad or laptop. But if you happen to have a child, this bag is designed with you in mind! A spacious enough diaper backpack (size: 12"x8"x16.5", 26L), and stroller straps. Tons of space - Baby bag includes 2 main compartments, 5 insulated pockets (Fit for All Major Baby Bottles), a wipe pocket. Pocket for tablets and laptops up to 15.6". Multiple pockets with easy-glide zippers makes this nappy changing backpack easily accessible with one hand. Durability & Comfort - Made of tear-resistant water resistant fabric, strong zippers and lining. Reinforced cushioned shoulder straps and padded back panel will distribute the load evenly on your shoulders and back for long time wearing. Convenient & Thoughtful - Cushioned shoulder straps, easy-grab top handle, and convenient stroller clips allow you to use this diaper bag as a travel essentials backpack, a handbag or attach to your stroller..
