Built for high-output adventures, this ultralight insulated vest combines the exceptional breathability of Polartec® Alpha® Direct with the air-permeable protection of Pertex® Quantum Air, delivering outstanding comfort across a wide range of conditions.

The Pertex® Quantum Air outer fabric is engineered to balance wind resistance with airflow, allowing excess heat and moisture to escape while providing protection from cool winds. The result is superior climate control during intense activity.

Inside, Polartec® Alpha® Direct active insulation provides warmth without bulk. Its lofted knit construction eliminates the need for a separate lining fabric, reducing weight while maximizing breathability, moisture management, and fast drying performance.

FIELD-TESTED BY ALPINE ATHLETES & MOUNTAIN GUIDES

Every product we create is developed with one goal: to perform in real mountain conditions. From the first prototype to the final version, each piece is tested where it matters most—not in a laboratory, but on rock, ice and snow.

This vest has been field-tested by alpine athletes and mountain guides during technical climbs, glacier approaches, long alpine routes and fast-moving ascents. Their feedback has shaped every detail, ensuring the right balance of protection, breathability and freedom of movement.

The result is equipment you can trust when conditions become unpredictable. Built for demanding mountain environments, refined through real-world experience, and ready for your next objective.
