A CimAlp® Innovation, this 3-layer rip-stop fabric is thin but strong, and it is equipped with the latest ULTRASHELL® membrane.

This sets new standards:

Breathability > 80'000MVP
Waterproof > 20'000mm of water or 20'000 Schmerber.

This level of performance is achieved by a fabric structure with even finer pores, which allows for better airflow while being more resistant.
