NEW TILAMI Rolling Backpack, the perfect companion for school, business, and travel commuters. This waterproof backpack with wheels is designed to make your life easier and more convenient. With a spacious 55L extra-large capacity and reasonable partition, this rolling backpack offers ample storage space for all your essentials. Whether it's your laptop, books, folders, pencils, lunch boxes, or water bottles, everything can be neatly organized and easily accessible. Featuring 18cm (7-inch) large wheels, this backpack is specifically designed for climbing stairs. With the two adjustable ABS material handles, children of all ages can effortlessly navigate any terrain, making it ideal for any occasion. Safety is our top priority. That's why we've incorporated a double-sided night light reflective design. A long reflective strip is hand-embedded on the front, complemented by reflective detailing on the shoulder straps. This enhances visibility for vehicles at night and ensures that your kids are noticed in the dark, providing greater peace of mind for parents. Comfort is key when it comes to a rolling backpack, and we've taken that into consideration. This backpack is ergonomically designed with an adjustable handle, a padded back panel, and shoulder straps. Not only does it promote proper posture, but it also facilitates effortless transport, even with heavy loads. We understand that durability is essential, so we've reinforced the shoulder straps and handles to be firm and reliable. The soft sponge cushion adds extra comfort, and the backpack is water-resistant, protecting your electronics and papers from unexpected spills or rain.
