TorrentStretch membrane provides effective protection against rain and wind
This is our proprietary 3-layer (3L) laminate, developed for intense activity in demanding weather conditions. A waterproof rating of 30,000 mm provides reliable protection during heavy rain and strong winds. The integrated membrane with micropores blocks water from the outside while efficiently transporting moisture generated by the body outward.


Active ventilation for heat and moisture efficient management
Breathability rated at 30,000 g/m2/24h and a low RET value of 7 means very low resistance to vapor transfer, a key factor during high-intensity activity. The TorrentStretch membrane efficiently dissipates excess heat and moisture, preventing overheating.
YKK AquaGuard waterproof zippers
Provide additional rain protection without compromising zipper smoothness. The convenient two-way main zipper, finished with a Prym snap, maintains jacket tightness while allowing easy adjustment during movement.


The outer layer is protected by a water-repellent DWR coating
Durable water repellency increases resistance to dirt, reduces material absorption, and slows moisture penetration.

Adjustable hood
A 2-point adjustment allows precise fitting to the head, while the high collar additionally shields the face from wind.

Underarm ventilation
Zippered vents precisely increase airflow and stabilize the fabric during movement.

Cuff and hem adjustment
Hook-and-loop adjustable cuffs and a drawcord at the hem let you adapt the jacket to changing conditions.


We designed the Hardshell Squall as a year-round outer layer for work in variable conditions. In summer, it protects against wind and precipitation; in winter, it serves as a base for a layered clothing system.
Chest pockets
Two chest pockets are positioned higher, remaining accessible even when wearing a backpack with a fastened hip belt.
Internal pocket
Provides additional protection for documents or a phone against adverse weather conditions.
