My son needed for physical education a gym bag in the 1 pair of sneakers (Gr. 38), sports pants and shirt fit, and also fit into the school bag so he would not have to carry around 2 parts on the bus. This sports bag has a good size, everything fits in and it weighs almost nothing. Anyone who has ever weighed the school backpack with contents, knows why that's important. As color I took yellow, because it is a signal color and my son very much moved his things and then not reflected. Now that we've "lost" 2 x dark blue sports bag in the depths of the locker room, I hope now with the yellow sports bag on prolonged use.
