About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

TA Trend Atelier
Children’s thermal bag/lunch bag

Manufacturer’s product description

The children’s thermal bag/lunch bag from Trend Atelier is a well-designed companion for school, excursions, or everyday family life. The manufacturer uses 100% recycled polyester and a PFC-free, water- and dirt-repellent impregnation —a plus in terms of sustainability and durability. Available in two sizes – Coolie (1.5 liters) and Colden (2.5 liters) – the lunch bag is designed to meet a variety of needs: from a small snack bag to a compact box for complete meals. With its comfortable carrying handle and practical inner compartment, it is also easy to handle and well organized.

Our test shows whether the practical claims of the product are equally convincing in practice.

  • Water- and dirt-repellent surface
  • Interior with mesh compartment
  • Lightweight and compact
  • Child-friendly
  • Pay attention to dimensions depending on your needs

As part of our practical test, we thoroughly examined the children’s thermal bag/lunch bag and documented the results using the specified test methods. Even when filling it, it is clear that the lunch bag is well suited to children’s everyday lives. Both versions – with a volume of 1.5 liters and 2.5 liters – offer enough space for lunch, fruit, and snacks. However, the smaller version only fits a small water bottle, making it more suitable for shorter trips or kindergarten. The small mesh compartment inside keeps things tidy and prevents smaller snacks from sliding around. In terms of water repellency, the lunch bag impresses with its impregnation. Water and dirt roll off the surface reliably – even after repeated use. This keeps the material dry and effectively protects the contents from moisture. The handle is comfortable to hold , the bag is very light and can be carried easily even by smaller children. Its compact shape also means it fits well into school bags or backpacks. The product can be easily cleaned with a damp cloth. The material remains dimensionally stable and odorless. Overall, the lunch bag is a well-designed and practical everyday companion for children – robust, functional, and manufactured in an environmentally friendly way.
