The perfect college backpack
The Daybag is your perfect companion for the city. Exclusively for students or all those who have never stopped learning...our Daybag masters every day situation. You can quickly access all your most important things and the reflective surface of the backpack protects you during the night.

A year ago we were desperately looking for a backpack with many functions, safety features, but also with a really good design. No results. We asked our friends. They too were at a loss. So we designed the perfect backpack ourselves. It was important for us to express our passion for technology, cycling and design.

The perfect size
- you can easily store your laptop or tablet in a lined compartment. The rest of the backpack has the perfect size to cope with every day situations without making the daybag too bulky.

Safe in traffic
- A large part of the backpack consists of a reflective surface. So you can get around the city safely with the Daybag, especially in the dark season.

Simple design
- The simple design of the backpack turns the daybag into a real eye-catcher. The minimalist look allows the backpack to be combined with any outfit.
