INCLUDING CHINSTRAP MACLIP AND CRASH ABRORBER The perfect fit and optimal seal of the Protos integral Arborist make it perfect for working at heights, where head and face protection are essential. The ear and face protection are integrated into the structure of the head protection, thus preventing the possibility of getting stuck on branches and protruding parts. The special design of the Protos Integral allows fresh air to flow from all sides and out of the ventilation opening, this ensures the head does not collapse even during the most strenuous activities. The KlimaAIR set can be changed and washed at 30C to maintain hygiene. The chin strap guide is developed so that it does not slip under the ear protection which could compromise noise reduction or comfort. Obviously Protos Integral Arborist is certified in accordance with EN 397, EN 12492, EN 1077 and EN 1078. Version available as ANSI Z89.1. For safety reasons, the exterior of the Protos should be replaced every 5 years (starting from the date of manufacture), this is available separately. For hygienic reasons we recommend washing the internal parts regularly and replacing them every 2-3 years in case of daily use
