Comfortable ventilated helmet for work at height and rescue. With its strong chin strap, the VERTEX VENT helmet sets the standard in head protection for workers at height. Ventilation holes with adjustable sliding shutters allow air to circulate in the helmet when needed. Its sixpoint mesh headband ensures comfort, and its CenterFit adjustment system adjusts the headband and keeps it centered on the head. The VERTEX VENT is designed to optimally accept hearing protection, the specific VIZIR visor, or a PIXA headlamp.
