This backpack measures 12.9 x 5.1 x 17.7 inches with a 17L capacity, making it ideal for daily outings, travel, and outdoor activities. The main compartment features a wide opening for easy access to your belongings, with internal dividers and a clear pocket for organizing documents, phones, wallets, and more. The front zipper pocket offers dual-direction zippers and includes a document divider, while the front slip pocket is perfect for coins, IDs, or a power bank. Side mesh pockets can hold items like water bottles or umbrellas. The thick padded straps combined with a breathable back pad reduce shoulder pressure and enhance wearing comfort. Reflective strips on the front and side pockets increase visibility at night. We recommend hand washing and air drying; do not bleach or iron at high temperatures.
