The gym bag is now no more space saver, but a normal sports bag. My son takes him to school sport, because he still can stow in your backpack the filled bag and have to take any additional sports bag. In the bag fit sport footwear (Gr. 39), as well as a sports pants and a T-shirt. More is already scarce. For school sport or as a pure Schuhbeutel okay, but if more (change of clothes, rain jacket or towel) is required, the bag is too small. Advantage: + Weight: The bag weighs next to nothing, therefore also ideal for school backpack, which is hard enough even without sports stuff. + Quality + Wide range of colors + Price
Disadvantage: except for the limited capacity, no :-).
