This PVC itself is widely used as a waterproof material, so the business backpack does not let water through the fabric and can maintain its waterproof performance for a long time. This material is also known for its ease of care. In addition, all zippers on the exterior part are waterproof zippers, effectively preventing rainwater from entering. (*Not completely waterproof.) ✅ [Excellent usability] There are many pockets, small and large, so it is easy to sort and take out. 15.6-inch PCs and tablets go in the PC pocket, small items such as notebooks, pens, and wallets go in the sub-pockets, documents, A4 files, clothes, etc. go in the main pocket, and foldable umbrellas and water bottles go in the side pockets. You can easily carry all the items you need for daily life together. The main pocket opens wide at about 75 degrees, so you can easily put things in and take them out, and it is a stylish backpack that can hold a lot. ✅ [Comfortable to carry] The backpack itself weighs only 0.8 kg, making it an ultra-lightweight type that you won't even notice. In addition, the ergonomic belt and the entire back are made of thick cushioning and highly breathable mesh material, which reduces the burden through a decompression effect. Even on hot days, it effectively releases unpleasant stuffiness and feels refreshing. The structure efficiently transfers the load to the waist, so it fits well and is comfortable to carry for long periods of time without getting tired. ✅ [High safety & multi-functional] Reflective material that strongly reflects car headlights is installed on the shoulder of the backpack, and nighttime visibility is up to 100m, so you can keep safe when riding a bicycle or motorcycle at night. It also has the necessary functions for a backpack. 1. Holder for keys etc. on the front pocket (saves you the trouble of looking for keys) 2. Zipper pocket on the shoulder for storing transportation cards (you can pass through ticket gates without stopping) 3. Comes with a dedicated belt that can be attached to a suitcase (carrier supporter releases shoulders) ✅ [Reliable 6-Month Warranty] This product comes with a 6-month quality warranty from the date of purchase.
