In the pursuit to redefine the outdoor apparel industry, CimAlp’s ULTRASHELL® technology underwent rigorous testing, both in the laboratory and in real-world conditions. Traditionally, hydrostatic testing and moisture vapor transmission rate (MTVR) were used to assess a garment's waterproofness and breathability. However, with ULTRASHELL®, we also considered air permeability as a crucial factor.

We collaborated with our team of elite athletes, they played a crucial role in the prototyping, development, and testing of ULTRASHELL® products. Every aspect of the products was scrutinized by world-class athletes who challenged our design and engineering teams to reimagine the future of technical outerwear.

From the highest peaks to the most challenging descents, our breathable-waterproof ULTRASHELL® technology was extensively tested for over 400 continuous days by our elite athlete team in the toughest conditions on Earth.

The result is a revolutionary product that offers maximum protection from external elements while allowing your body to breathe and stay comfortable. This unique combination of features makes ULTRASHELL® a must-have choice for all outdoor enthusiasts seeking the pinnacle of comfort and protection.
