TorrentStretch® membrane provides effective protection against rain and wind
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, while micropores block outside water and transport body moisture outward.


Active ventilation for heat and moisture efficient management
Breathability rated at 30,000 g/m²/24h and a low RET value of 7 offer very low resistance to vapor transfer. TorrentStretch membrane dissipates excess heat and moisture during strenuous activity. YKK AquaGuard waterproof zippers offer rain protection, supported by a two-way main zipper with a Prym snap.


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

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

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

Cuff and hem adjustment
Hook-and-loop adjustable cuffs and a drawcord at the hem allow adaptation to changing conditions.


Year-round outer layer
Protects from wind and precipitation in summer and functions as an outer shell over technical insulation layers in winter.
Chest pockets
Two chest pockets are positioned higher to remain accessible while wearing a backpack with a fastened hip belt.
Internal pocket
Provides additional protection for documents or a phone against adverse weather conditions.
