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.
