KLATTERMUSEN KLATTERMUSEN Backpack Mimer22 Purchased over 10 years ago and used for about two years for commuting (20 minutes each way). It has been stored at home, but I haven't used it since then. I have severe shoulder stiffness, and backpacks generally don't suit me, but this KLATTERMUSEN backpack significantly alleviated my shoulder stiffness, and I remember that it reduced the stiffness even while wearing it. 【Size】 Width: Approximately 30cm Height: Approximately 50cm Depth: Approximately 11cm 【Description, Functionality, Storage Capacity】 From KLATTERMUSEN, the 'Mimer22' is the smallest backpack in the series with a capacity of 22 liters. It's the perfect size for daily use, cycling, and day trekking. KLATTERMUSEN backpacks mainly use recycled nylon 'MIPAN Regen' produced from old fishing nets and carpets. In addition to the advantage of being produced with less energy and chemical consumption, it is also very light, durable, and has excellent waterproof properties, boasting high functionality that you wouldn't expect from recycled fabric. The top zipper opens to about half the body, making it easy to check and take out the contents, using a unique system. On the front, there is an outer pocket made of stretch nylon with excellent elasticity and durability. On one side, there is a flat side pocket made of the same stretch nylon, which can be used as a bottle holder or as a tool pocket for storing mobile phones, etc. Inside, there is an organizer pocket, and it is also equipped with a whistle and reflector, which are standard equipment for KLATTERMUSEN products, providing ample functionality. It is the smallest size in the KLATTERMUSEN backpack series and can be used casually like a daypack, and it is a unisex and easy-to-use style. Please be sure to check the photos posted and refrain from purchasing if you are a perfectionist.
