The HPRC case series is made from the highly durable TTX01 resin special plastic, making it capable of withstanding the toughest conditions and highest demands with ease. The cases provide secure and reliable protection against water, dust, light, and acids. The material is extremely robust, impact-resistant, and shatterproof, and the cases are waterproof.

Extreme weather conditions and temperature fluctuations from -40 to +80 degrees Celsius do not affect the cases. They are therefore also excellent for air and freight transport. All cases feature reinforced edges, an integrated address label, and a special valve for pressure equalization. The hinges of the smooth closures are steel-reinforced and are designed in such a way that they are nearly impossible to open by themselves or to pop open upon impact. A load capacity of around 30 kilograms provides ample reserves for heavy items.

The interior layout consists of a separate Cordura bag with Velcro dividers, which can be exchanged or replaced as needed. The carrying/soft grip module has been specifically designed with ergonomic and stability considerations in mind, making it very comfortable to carry.

By using TTX01 resin and other high-quality materials, such as aluminum for the trolley versions, a weight reduction of approximately 25% has been achieved while even increasing stability compared to common models from other manufacturers.
