2.5L membrane protection from rain and wind
Water resistance of 20,000 mm effectively protects during heavy rain and strong winds. The integrated microporous membrane blocks external water and efficiently wicks body moisture away.


Active ventilation removes heat and moisture
Water vapor permeability of 20,000 g/m²/24h prevents overheating during physical activity. Taped seams, a two-way YKK zipper, and a Prym snap maintain watertight protection.


Water-repellent DWR coating
Durable PFC-free water repellency enhances resistance to dirt and slows moisture penetration into the fabric.

Adjustable hood
A 2-point adjustment allows precise fitting, 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 cuffs and a bottom drawcord allow the jacket to adapt to shifting outdoor conditions.

Front pockets
Zippered pockets covered with protective strips limit water ingress, ideal for hands or small items.

Shoulder pockets
Upper sleeve zippered pockets keep phone or documents safe from wet weather.
