The chin strap fits the shell of the PROTOS® Integral helmet. The chin strap can be attached to the prefabricated loops of PROTOS® helmets by using the insertion buttons. Thanks to the strip guide on the neck shell, the chin strap will always fit smoothly. Moreover, it cannot slip under the Hearing Protection Support. The Chin Strap includes a magnetic closing system, which can be released even under pressure easily.
In case of daily use, Protos recommend replacing the chin strap every 1–2 years.
