With a large 30L capacity, it offers excellent storage. A4-sized notebooks fit perfectly. It also has a cushioned pocket convenient for storing laptops and tablets. There's a mesh side pocket on the side that can hold a 500ml PET bottle. The back is made of mesh and cushioning for comfortable carrying. The material uses durable CORDURA fabric from Invista, an American company. It has about 7 times the strength of nylon. While not waterproof, it has excellent water repellency. The zippers are woven zippers developed by YKK specifically for bags. They have superior abrasion resistance compared to conventional zippers, making them tough and durable. Thank you for viewing.
