The Pfanner PROTOS-WB Protos Helmet is a versatile option suitable for construction, forestry, arborist work, and climbing operations. Its integrated chin strap, visor, neck protection shell, and ear protection offer both convenience and flexibility. With a secure neck protector, the helmet stays in place even when working at different angles or upside-down. The Pfanner Protos arborist helmet is the most advanced on the market, featuring exceptional energy absorption, lightweight design, and unparalleled breathability. Its side impact protection sets it apart from competitors and establishes it as one of the safest climbing helmets available. Please note that Protos helmets now come with a grey foam insert, rather than the green koroyd used in previous versions.
