A bag-in-bag is convenient for organizing the contents of your bag. The double zipper opens in an L-shape, making it easy to take things in and out. The A5 size has a main storage pocket that can hold a tablet PC of about 10 inches. It also has a brushed inner pocket that is gentle on the tablet PC screen, and can hold a tablet PC of about 8 inches. Reinforced side plates provide structure and prevent bending inside the bag. The main fabric is water-repellent, making it resistant to water and dirt. *The water-repellent treatment is only on the outer fabric. It is not completely waterproof. The pockets for storing small items on the front are placed as high as possible. This allows you to quickly and stress-free retrieve what you need from your bag. The pockets made of stretch fabric fit the contents without a flap, so you can store various small items such as notebooks and books.
