Super backpack. Both classroom and practical to use. I like because it combines the convenience of sportswear to a sober design and class that passes easily across when doing business trips. The many pockets are thoughtful and useful. This is my 2nd SwissGear bag (Wenger) and strength is always by appointment. Just one negative point: the volume of the main pocket is not very consistent and it is difficult to put something over 20 cm wide.
