Built for cold, wet, and relentlessly demanding conditions

The Extreme Jacket is built for cold, wet, and relentlessly demanding conditions. Trusted by professionals and mountain users for decades, it delivers uncompromising protection when weather and terrain leave no room for failure.

The combination of a tough, windproof PERTEX® QUANTUM outer and high-loft pile lining creates a system that’s warm, breathable, and highly weather resistant; even when working hard in cold, damp environments. The directional fabric design moves moisture away from the body, keeping you warm and comfortable during prolonged use.
