Based on the legendary Pro Altitude jacket—trusted by Norwegian State Rangers and National Park Rangers—this next-generation shell is built to perform in the most demanding environments.

Key Features

Award-Winning Waterproofing
Equipped with the ISPO Award-winning X-Pore™ membrane, made from recycled materials. Fully waterproof, windproof, and exceptionally breathable.

Extreme Durability
Built with Ravnø’s proprietary Microfighter™ fabric, developed for abrasion resistance and long-term performance in harsh terrain.

Smart Storage
Designed with multiple practical pockets, including:

• Two handwarmer chest pockets

  To pass through your antenna from the inside pocket and both layers (rather than just outside pocket) – you will need to make a second cut.

Nano-technology coating repels water, oil, and dirt to keep the jacket clean and dry under rugged conditions.

Eco-Conscious Manufacturing
Made in Europe using recyclable materials. Covered by the Ravnø 10-year warranty.
