What is DerDieDas?

DerDieDas is a brand of backpacks and school bags. It is a brand of a German manufacturer whose website sits alongside the Undercover Germany corporate pages.

Products and positioning

The core range is the ErgoFlex school bag, which comes in four models of different size and weight.

  • ErgoFlex Tiny
  • ErgoFlex Easy
  • ErgoFlex Light
  • ErgoFlex Superlight

Some models are offered as an exclusive collection with reflective surfaces or LED lights, which supports visibility on the school run.

Accessories

Around the bags the brand sells a small ecosystem of add-ons. These include swap-on buttons for personalising a bag, water bottles, sports bags, blinkies and rain capes.

The four models give parents a choice by size and weight, and the swap-on buttons let children personalise their bag.

Why it matters

DerDieDas is typical of the school bag category, where ergonomics, safety features and personalisation drive the product rather than seasonal fashion.
