Thank you for viewing. This item is new and available for immediate purchase. 【3-Layer Multifunction & 7 Pockets】This 3-layer backpack is designed with multiple, separate pockets for organization and functionality. This men's backpack has a total of 7 pockets, allowing you to store A4-size files, a 15.6-inch PC, an iPad, textbooks, pens, umbrellas, clothing, drinks, lunch boxes, and more all at once. The main pocket of the backpack has an independent laptop pocket that can fully accommodate a 15.6-inch laptop. The two side pockets can store cups and folding umbrellas. 【Excellent Waterproof Fabric & Durability】The surface of this business backpack is made of high-quality polyester Oxford fabric. The backpack is also treated with a high-density waterproof coating, providing excellent water repellency. Water beads up and rolls off the surface, protecting your valuables from sudden rain and unexpected scratches. You can carry your valuables with peace of mind. (While designed to be water-resistant, it is not completely waterproof. Please understand.) 【Durable with Excellent Sewing Technology】Durable zippers are used, and reinforcement is important to prevent tearing and fraying. Especially at the base of the straps, where a large load is applied, it is sewn with three nylon threads to reinforce the seams, improving load capacity and durability. This casual backpack can be easily cleaned by simply wiping it with water, even if it gets dirty. It is wrinkle-resistant and stain-resistant, making it very easy to care for! 【3D Breathability! Comfortable to Wear】The shoulder straps and the entire back are designed with ergonomics in mind, using low-rebound and high-rebound cushions, and a mesh panel. The cushioning and breathability are outstanding! It provides a comfortable and pleasant wearing experience on the body, reducing the burden through the decompression effect. Even on hot days, the bag effectively releases unpleasant stuffiness and feels refreshing. The shoulder straps are the appropriate thickness, reducing the burden on both shoulders, and allowing you to carry it comfortably. 【Lightweight & Great for Various Occasions】The backpack itself weighs only 0.6kg and measures 45*31*14, making it an incredibly lightweight type. With its excellent functionality and lightweight design, this backpack is suitable for both men and women of all ages, with a simple design and great functionality.
