TorrentStretch membrane protection
This proprietary 3-layer (3L) laminate is 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 microporous membrane blocks external water while transporting internal moisture outward.


Active ventilation and YKK AquaGuard zippers
A breathability rating of 30,000 g/m²/24h and low RET value of 7 deliver very low resistance to vapor transfer. The membrane dissipates excess heat during sustained activity. YKK AquaGuard zippers maintain water resistance, supported by a two-way main zipper finished with a Prym snap.


DWR outer coating
Durable water repellency enhances dirt resistance, reduces fabric absorption, and slows down moisture penetration.

Adjustable hood
A 2-point adjustment allows precise fitting, accompanied by a high collar that shields the face from wind.

Underarm ventilation
Zippered underarm vents increase airflow and heat dissipation during movement.

Cuff and hem adjustment
Hook-and-loop cuff adjusters and an elastic bottom drawcord allow adaptation to changing weather.


Year-round performance
Designed to serve as a rain and wind shell in warmer months, or as a protective exterior shell over technical thermal and insulating layers in cold weather.
Chest and internal pockets
Two chest pockets are positioned higher to remain fully functional while wearing a backpack with a hip belt. The inner pocket offers protected storage for phones or documents.
