Frequently asked questions

All the questions that may arise when it comes to buying a schoolbag.

What attracts the kids the most?

The lovingly and exquisitely crafted designs – there is one for everyone.

Is the quality right?

DerDieDas schoolbags and backpacks for school have been awarded for their performance characteristics. And they are equipped with lovingly crafted details.
Our designers involve school kids when it comes to product development.

Does a Leitz ring binder fit in? And what about the drinks bottle?

Of course.
A DIN-A4 (German standard format) ring binder fits easily into all our DerDieDas models. And all the side bags are designed for all the established drinks bottles.

What about stability?

DerDieDas backpacks are designed to be lightweight but to offer good stability at the same time. They should not, however, be used as seating accommodation.

Are the DerDieDas schoolbags and backpacks anatomically designed?

Absolutely. All DerDieDas backpacks have a height-adjustable chest strap that optimizes the seat. In addition, all backpacks contain a hip belt, which relieves shoulders and back by shifting the weight to the hips.

What about the weight?

The ErgoFlex MAX has an empty weight of only approximately 950 g, the ErgoFlex approx. 800 g – and the ErgoFlex Superlight, as the name reveals, only approx. 650 g!
The DerDieDas models are counted among the most lightweight schoolbags.

And what about safety?

The special retroreflective material reflects incident light, e.g. from the headlights of a car – for ideal protectiont at dawn and in the dark.

And what about the capacity?

With approx. 28 x 38 x 25 cm and a capacity of approx. 22 l (incl. front and side bags), the DerDieDas ErgoFlex and the DerDieDas Superlight are particularly flexible and offer a perfect fit thanks to their ergonomic design.

With approx. 29 x 39 x 25 cm and a capacity of approx. 22 l (incl. front and side pockets), the DerDieDas ErgoFlex MAX takes its name very well: optimal ergonomics and flexibility when packaged with expandable main compartment.

Why is the ErgoFlex called ErgoFlex?

…because it’s ergonomic – and flexible.

All DerDieDas schoolbags dispose of a back-friendly, breathable back padding with mesh lining. The shoulder straps are easily adjustable, a vertically adjustable chest belt optimises the fit. In addition, all schoolbags dispose of a hip belt that shifts the weight to the hips and thus relieves shoulders and back.

The models ErgoFlex and ErgoFlex MAX are additionally equipped with an adjustable back strap system that can be adjusted to the child’s back length. Thus, the schoolbag grows with the child throughout the whole primary school time.

One more point for the flexibility of ErgoFlex: it was not only designed for school but can also be used for leisure time.

How do I clean my DerDieDas?

DerDieDas schoolbags and accessories can easily be cleaned:
We recommend a soft brush and/or a cloth with a gentle detergent. Afterwards, wipe it with pure water.
