Safe: A backpack that brings you & your environment safer through the day. Thanks to the reflective material you will no longer be overseen.

Reliable: The backpack for your daily life. Due to the comfortable fit and a spacious main compartment system the Daybag won't let you down.

Waterproof: Don't give rain a chance. With the Daybag you no longer have to worry about your electronic devices getting wet.

Support a young startup: As a young startup we want to make the daily life safer & more comfortable. Become a part of this mission and bring yourself and others safer through the day!

A year ago we were desperately looking for a backpack with a lot of functions, safety features, but also with a really good design. No results. We asked our friends. They, as well, were at a loss. So without further ado, we designed the perfect backpack ourselves. It was important to 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 master all daily situations, without getting too bulky.

Safe on the Road -  A large part of the backpack consists of a reflective surface. So you can safely get through the city with the Daybag, especially in the dark months of the year. 

Simple Design - The simple design of the backpack makes the daybag a real eye-catcher. Due to the minimalist appearance, the backpack can be combined with any outfit.

Support a Young Startup - Are you interested in innovative products? You want to support a young start-up? Then you are absolutely right with us. We are 19 and 20 years old, come from Hamburg and founded our bag label about a year ago. Learn more

        Very cool backpack.And the reflection in the dark is great anyway. Like all products so far: clear 1* I absolutely recommend!




        The Daybag has a really great size for studying. A laptop, the most important accessories, a small pencil case and a few books fit easily inside.
