Pfanner Protos Arborist Helmet System
The Pfanner Protos Arborist Helmet System is a professional head, face, and hearing protection solution designed for arborists, tree climbers, and professionals working at height. Its integrated, low-profile design combines impact protection, hearing protection, and a retractable face shield into a streamlined helmet system that minimizes protruding components that could catch on branches or surrounding equipment.
Engineered for demanding work environments, the Protos features side and rear impact protection, adjustable ventilation, and an ergonomic fit system designed for comfort during extended use. The helmet's swept-back profile provides an unobstructed field of vision, while the adjustable neck support and balanced weight distribution help maintain a secure fit.
Integrated hearing protectors feature adjustable contact pressure and can be moved into their stored position when not required. The retractable mesh face shield provides additional protection from flying debris while maintaining visibility. Large, replaceable Klima-AIR moisture-wicking pads help manage perspiration during strenuous work.
The helmet includes an adjustable chinstrap for work at height. You can open or close the ventilation system to accommodate changing weather and working conditions.
