I'm selling this because I no longer use it. There are signs of wear on the zipper hardware and the bottom. Other important notes are listed in my profile. Please take a look. The fabric is highly durable and is a standard material used by Cote&Ciel, also used in other products. It's a versatile material that goes well with any outfit or season, suitable for both casual and smart looks. The design fits snugly against the back, making the weight feel lighter and reducing fatigue even when worn for extended periods. This is a high-end brand of accessories for iPhone/iPad/MacBook, designed by Paper Rain, the producer of "Damir Doma," a popular brand at Paris Fashion Week. Paper Rain has clients including industry-leading companies and organizations such as Apple, BMW, and FIFA, and is also focusing on research and development of recycled fibers. They are also involved in the development and production of world-class products. #CoteCiel #Cote&Ciel #Backpack #Backpack
