Daybag & Carryall Sling Bundle von OAK25

The perfect college backpack

Egal ob Bücher, Tablet oder Stifte. Mit unserem Rucksack kannst du alles, was du für die Uni oder für dein Studium benötigst, komfortabel verstauen. Während deiner Uni Zeit solltest du nicht über deinen Rucksack nachdenken müssen. OAK25 macht deinen Uni Alltag smart. Aber auch außerhalb der Uni ist der Rucksack perfekt geeignet. Als stylischer Rucksack für Studenten gehört natürlich auch dazu, dass du im Daybag Drinks oder Sportklamotten transportieren kann.

Große Bauchtasche für die Stadt

Unsere Carryall Sling ist ein echtes Platzwunder! Die Bauchtasche ist so groß, dass du ohne Weiteres deine Essentials, Drinks und sogar deine Kamera dabei haben kannst. Ganz bewusst haben wir uns dazu entschlossen, eine große Bauchtasche zu entwickeln, sodass man auch bei längeren Ausflügen nicht zwingend einen Rucksack mitnehmen muss.
