Our older son had a Dakine backpack in a smaller version. After this now after 7 years (!!!) gave up the ghost in daily use at school, he now wanted for Oberstufengymnasium a larger version. We are very pleased with the comfort and the space available. It fit in even large DIN A4 folder and sometimes things turn (shoe size 44). The two mesh pockets on the side are ideal for 0.5-liter bottles.
