Also in the protection of our technology, we have gone our own way. We have searched for a material that is lightweight and can withstand extreme loads. In the automotive industry, more specifically in the bumper production, we have found it. The material used,high-pressure polyethylene, is hot-drawn for our suitcases. Effect: Our cases hold temperatures of minus 40 degrees to 90 degrees plus and the most extreme impacts. The fact is: Since we use this material,there never has been a complained about a defective bag.
