Thank you for viewing. This item is new and available for immediate purchase. Color: Black 【Excellent Waterproof Fabric】The surface of the backpack is made of high-quality polyester oxford fabric. The men's backpack is also coated with a high-density waterproof coating, providing excellent water repellency. Water beads up and rolls off the surface, preventing water from seeping inside, reliably protecting your important items from sudden rain and unexpected scratches. You can carry your valuables with peace of mind. (Although designed to be water-resistant, it is not completely waterproof. Please understand.) 【Durable & Long-lasting】The backpack is highly abrasion-resistant, tear-resistant, and long-lasting. Even if it gets dirty, you can easily remove the dirt by simply spraying water or wiping it lightly. It is wrinkle-resistant and stain-resistant, making it very easy to care for! The back of the large-capacity backpack has thick cushioning material built-in, making it comfortable to wear for long periods. 【Waterproof Zipper Design】The casual backpack uses waterproof zippers and is carefully sewn, resulting in a product with a focus on quality. The fabric of the men's backpack is sewn tightly between the zippers, preventing rainwater from entering through the zippers. The parts that receive pressure are reinforced to prevent damage during use. This is a simple yet high-quality backpack. The zippers open and close smoothly, mesh well, and are not easily damaged. 【Large Capacity Storage】The main pocket of the backpack has an independent laptop pocket that can fully accommodate a 15.6-inch laptop. The PC backpack can store A4-size files, a 15.6-inch PC, iPad, textbooks, pens, umbrellas, clothes, drinks, lunch boxes, and more all at once. The two front outer pockets of the backpack can easily store small items that you want to take out at any time. The two side pockets can store cups and folding umbrellas. 【Lightweight & Versatile】The backpack body weighs only 0.55kg, making it an incredibly lightweight type that you won't even notice. With its excellent functionality and lightweight design, this backpack has a simple design and functionality that can be used by men and women of all ages. This men's backpack is perfect for everyday use, such as commuting, going to school, traveling, school trips, excursions, mountain climbing, cycling, going out, outdoor activities, as a gift, for disaster preparedness, and daily life.
