[Large Capacity 30L Backpack] Dimensions: (45+13cm x 32cm x 20cm), Weight: Approximately 1kg, Capacity: 30L. This men's backpack features a popular square design, wide gusset, SBS zippers, and 17 pockets for excellent storage, making it ideal for any occasion. Its large capacity and smart compartments allow for ample storage for essential items like a 17-inch laptop, A4-sized documents, and a few days' worth of clothes. Measurements may vary slightly due to manual measurement.
[Two-Layer Design] AISFA's unique two-layer design allows for separate storage space. The lower pocket is waterproof, allowing you to store shoes, lunch boxes, wet umbrellas, clothes, and more separately in the lower compartment. This is especially effective during the rainy season. When you don't need the expansion function, you can close the SBS zipper to create a hidden pocket.
[Water-Repellent] This waterproof backpack is made with high-quality PU-coated 1600D nylon for abrasion resistance, durability, and sturdiness. The PU coating enhances water resistance and gives the backpack a subtle sheen. The bag is also scratch- and stain-resistant, and if it does get dirty, you can wipe it clean with a quick wipe. *Please note that this bag is not completely waterproof.
[Safety Design] The reflective tape significantly improves visibility to cars and pedestrians at night, in the dark, or in rainy weather. This significantly increases safety and supports nighttime safety. The anti-theft design includes a hidden pocket on the back that is invisible to others when the backpack is on your back, so you can store your wallet for everyday use, or your passport or airline ticket when traveling, to prevent loss or theft.
[Ergonomic Design] The ergonomic design of the belt and back is achieved by using thick cushioning and highly breathable mesh material, which reduces strain through a decompression effect. The business backpack is designed to efficiently transfer the load to the waist, providing a comfortable fit and reducing fatigue even when worn for long periods of time.
[Useful in a variety of situations] This backpack is perfect for everyday commutes, camping, mountain climbing, business trips, travel, fishing, and more, thanks to its carry-on functionality. It's perfect for everyday use, as well as an emergency backpack. It also makes a great gift for yourself, Merry Christmas, Father's Day, birthdays, and more!
Separate PC Storage: The thick padding in a business backpack protects your laptop, tablet, and other items from shocks and vibrations. It also protects important documents and presentation materials from rain. A durable and waterproof backpack is essential for commuting.
[External USB Charging Port] The backpack has a USB charging port on the side, allowing you to connect a portable power source inside the backpack. By connecting it to the power source inside the backpack, you can charge your smartphone while listening to music or keeping your device charged while traveling. (USB cable included.)
