• Avon Protection HMK150 Riot Helmet Gas Mask Header

One Mask, Two Modes, Seamless Protection

The HMK150 is a revolutionary Helmet Mask Kombination System specifically designed for CBRN and Riot Control.

Avon has teamed with Schuberth to provide flawless integration of their HM50 to the Schuberth P100N Helmet.

Based on the widely deployed 50 Series mask platform, the HM system brings the pedigree of a mask proven for use in the harshest environments and is CE marked for CBRN Protection.

By a simple exchange of the harness for the helmet connecting straps, the mask converts to be compatible with a world leading Police helmet for use in non-CBRN environments which is approved to the most advanced German Police specification.  The full face respirator is connected to the helmet in seconds, as there is no need for the helmet to be removed. Respiratory protection is seamless.
