Backpacks
The adidas backpack selection here runs from the Defender Sports 33L to the Primetime School 41L. Those capacities help distinguish a sports load from a full school day, but the middle of the range needs attention too: Excel is listed at 34L, Prime at 37L and Foundation at 38L. Stadium Soccer 36L is a separately named sports model. Lay out books, clothing and any computer before choosing a volume; the same liter count can be divided among pockets in different ways.
